The Aisys CS2 Anesthesia System is intended to provide general inhalation anesthesia and ventilatory support to a wide ride range of patients (neonatal, pediatric, adult). The device is intended for volume or pressure control ventilation.

The GE Datex-Ohmeda Aisys CS2 is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients (neonatal, pediatric, adult). It represents one of the systems in a long line of products based on the Datex-Ohmeda Excel, Aestiva, Aespire, and Avance Anesthesia Systems. It is to be used only by trained and qualified medical professionals.

The Aisys CS2 supplies set flows of medical gases to the breathing system using electronic gas mixing. Interfaces to control the system include the touch screen, keypad and rotary controller on the main display unit. Selected gas flows are displayed as electronic flow indicators on the system display unit. The Aisys CS2 is equipped with a pneumatic back-up O2 delivery system and traditional flow tube, as well. A large selection of frames, gases, and vaporizer cassettes are available to give the user control of the system configuration. The Aisys CS4 systems are also available in pendant models. The system shall support a maximum of two-cylinder supply connections mounted inboard on the machine and supported by cylinder yokes. All models have O2. The Aisys CS2 comes with up to two optional gases (air, N20). Safety features and devices within the Aisys CS2 are designed to decrease the risk of hypoxic mixtures, agent mixtures and complete power or sudden gas supply failures. The Aisys CS2 system is available with optional integrated respiratory gas monitoring. When supplied as an option, the integrated respiratory gas monitoring is provided via the CARESCAPE Modules cleared via K123195 (E-sCAiO, EsCAiOV) and K150245 (E-sCAiOVX). The Aisys CS2 is also compatible with legacy M-Gas and E-Gas modules which are in the installed base but are no longer in forward production (M-CAiO and M-CAiOV cleared via K001814, and E-CAiOVX cleared via K051092).

The above modules can be physically integrated into the Anesthesia device, receive electronic power from the said device and communicate measured values to the said device for display on the system display unit.

The anesthetic agent delivery for the Aisys CS2 is controlled via an anesthesia computer through user input from the central display. The vaporization technology is based upon the electronic vaporizer cleared as part of the Datex-Ohmeda Anesthesia Delivery Unit (ADU) cleared via K973985. An Aladin 2 is inserted into the active cassette bay. The cassette holds the agent to be delivered - Isoflurane, Desflurane or Sevoflurane. Agent is delivered as a percent volume/volume. The Aisys CS2 is designed to allow only one active cassette at a time. Per the user input into the main display, valves within the active cassette bay will open and allow agent to be delivered. The agent is mixed with gas from the FGC unit. After mixing, the combination of gases and agent is delivered to the breathing system and then onto the patient.

The Datex-Ohmeda 7900 Anesthesia Ventilator is used in the Aisys CS2. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber, bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple and secure setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is regulated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices.

Ventilator modes for the device include Volume Control (VCV) Mode, Pressure Control (PCV) Mode (Optional), Synchronized Intermittent Mandatory Ventilation with Pressure Control Ventilation -Volume Guaranteed (SIMV/PCV-VG) Mode, Synchronized Intermittent Mandatory Ventilation with Pressure Support Ventilation (SIMV/PSV) Mode, Pressure Support with Apnea Backup (PSVPro) Mode (Optional), Synchronized Intermittent Mandatory Ventilation with Pressure Control (SIMV-PC) Mode (Optional), Pressure Control Ventilation- Volume Guaranteed (PCV-VG) mode (Optional), and Continuous Positive Airway Pressure/ Pressure Support Ventilation (CPAP-PSV).

Ventilator parameters and measurements are displayed on the system display unit.

The system display unit is mounted to an arm on the top shelf of the Aisys CS2. The arm is counter balanced and capable of moving vertically and/or horizontally, and tilting the display, enabling the user to position the display to the most advantageous viewing position. The arm length is limited such that the display position is always within the footprint of the Aisys CS2 frame. The arm also supports the mounting of additional display units for a variety of patient monitors.

Several frame configurations are available, including one that allows for the physical integration of the GE Monitors (cleared Carescape B850 via K092027 and B650 cleared on K102239). This configuration also provides cable management solutions such that the necessary connections from the monitor display unit to the monitor are hidden within the Aisys CS2 frame. An additional option allows the monitor to be linked to the power supply of the Aisys CS2 such that when the Aisys CS2 is turned on, the monitor is also turned on. Additional configurations allow for the mounting of various patient monitors on the top shelf of the Aisys CS2.

This document is a 510(k) premarket notification for the Aisys CS2 anesthesia system (version 11). It primarily focuses on demonstrating substantial equivalence to a predicate device (Aisys CS2 version 10) through non-clinical testing. Therefore, it does not contain the detailed information about acceptance criteria and a study that proves the device meets those criteria in the way typically found for a diagnostic or AI-driven device.

Based on the provided text, here's a breakdown of what is and is not available:

1. A table of acceptance criteria and the reported device performance

No explicit table of acceptance criteria and reported device performance in terms of diagnostic metrics (e.g., sensitivity, specificity, AUC) is provided. This is because the submission is for an anesthesia system, and the "performance" is related to its functional capabilities and compliance with safety standards, rather than a diagnostic accuracy.

The document lists various verification tests and what they verify. For example:

• Privacy and Security: Verifies functionality including an option to disable viewing patient identifiable information.
• Duplicate Interface Detection: Verifies functionality including that the system continues communication with its clients even if a duplicate IP condition is detected.
• Ethernet Interface: Verifies functionality including that the system supports 100Mbps speed and full duplex settings.
• Network Hazard Mitigation: Verifies that the system has no open ports except for specific clients.
• Network Requirements: Verifies that the system supports clock synchronization with a network device.
• Sapphire and HL7: Verifies communication protocols.
• Address Resolution Protocol Requirements: Verifies correct system subnet mask functionality.
• Respiratory Gas Monitors: Verifies all requirements related to Respiratory Gas Monitors, including functionality of the Sample Gas Return option.
• Monitoring Only Mode: Verifies functionality including O2 being administered through the auxiliary O2 port when the mode is enabled.
• System Hazard Mitigations: Verifies functionality including that the system performs as intended during a recovery state.
• Materials Testing: Includes Volatile Organic Compounds, Particulate Matter Testing, Bacterial Filter Efficiency Testing, Viral Filter Efficiency Testing.
• Reprocessing Instructions Validation Testing
• Verification testing for electrical safety and electromagnetic compatibility: Compliance to AAMI / ANSI ES60601-1:2005/(R)2012, IEC 60601-1-2: 2014, and ISO 80601-2-13: 2011.

For each of these, the implicit "acceptance criterion" is that the system successfully performs or complies with the stated function or standard. The "reported device performance" is the conclusion that these tests were passed and the system is safe and effective.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not applicable / not provided for this type of submission. This device is an anesthesia machine, not typically tested with "test sets" of patient data in the same way an AI diagnostic device would be. The testing described is functional and safety verification.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not applicable / not provided. There is no "ground truth" establishment in the context of diagnostic accuracy for this device. Ground truth is usually relevant for AI/ML models being validated against expert-labeled data.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable / not provided. Adjudication methods are used to resolve discrepancies in expert labeling for ground truth, which is not relevant here.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This information is not applicable / not provided. This is an anesthesia machine, not an AI-assisted diagnostic tool for human "readers" (e.g., radiologists interpreting images). An MRMC study would not be relevant for its evaluation.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable / not provided. This is an anesthesia machine. While it contains software, it is not a standalone AI algorithm in the diagnostic sense. It is a system intended for use by trained medical professionals. The software updates mentioned are for standards compliance and usability enhancements, not for independent diagnostic decisions.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

This information is not applicable / not provided. As explained, there is no "ground truth" akin to diagnostic accuracy for this device. The "ground truth" for its performance is its ability to meet engineering specifications, safety standards, and functional requirements.

8. The sample size for the training set

This information is not applicable / not provided. This device is not an AI/ML model that would have a "training set" of data in the typical sense. The software updates are developed and verified through standard software engineering practices.

9. How the ground truth for the training set was established

This information is not applicable / not provided. As there is no training set for an AI/ML model, the concept of establishing ground truth for it does not apply.

In summary, the provided document is a 510(k) summary for an anesthesia system. The "study" proving it meets acceptance criteria consists of a comprehensive set of non-clinical verification and validation tests covering:

• Software validation (including enhancements like EcoFlow improvements, Monitory Only mode, Network Connectivity, Privacy and Security, etc.)
• Compliance with electrical safety, EMC, and specific medical device standards (e.g., IEC 60601-1, ISO 80601-2-13).
• Materials testing.
• Risk analysis and design reviews.

The acceptance criteria are implicitly that the system functions as intended, meets its specifications, and complies with all relevant safety and performance standards. The "study" is the extensive report of these non-clinical tests, and the conclusion is that the modified device is substantially equivalent to its predicate. Clinical testing was not deemed necessary for the changes introduced in version 11.

Here's an analysis of the provided text regarding the acceptance criteria and study for the GE Datex-Ohmeda Engström Carestation and Engström Pro ventilators.

This 510(k) submission (K140575) is primarily for the addition of an alternate integrated air compressor (EVair) to the existing GE Datex-Ohmeda Engström Carestation and Engström Pro ventilators, which were previously cleared under K111116. The submission states "There have been no changes to the intended use or fundamental scientific technology." and "The addition of the alternate compressor, EVair, does not affect the safe or effective use of the ventilator as the compressor interfaces with the ventilator in the same manner, and performs in an equivalent manner. There is no change to the Engstrom performance as a result of this change." Consequently, the acceptance criteria and studies focus specifically on the new compressor and its functional equivalence, rather than a broad re-evaluation of the entire ventilator system.

1. Table of Acceptance Criteria and Reported Device Performance

Given the nature of this 510(k) (adding an alternate component), the acceptance criteria are framed around functional equivalence and safety of the new EVair compressor compared to the predicate EVair03.

2. Sample Size Used for the Test Set and Data Provenance

The provided document describes nonclinical testing only.

• Sample Size: The document does not specify a quantitative "sample size" in terms of units tested for the compressor, nor does it refer to patient data. Testing appears to be on developmental units of the EVair compressor integrated with the Engström ventilators.
• Data Provenance: The testing was "nonclinical," meaning it did not involve human patients. It was conducted by the manufacturer, Datex-Ohmeda, Inc. (GE Healthcare). There is no mention of country of origin for specific test data, but the company is based in Madison, WI, USA. The testing is prospective in the sense that it evaluates a newly designed component (EVair compressor) before its market release.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

• The concept of "ground truth established by experts" is not directly applicable here as this is a nonclinical engineering and functional equivalence study for a medical device component.
• The ground truth for this type of evaluation is typically defined by engineering specifications, regulatory standards (e.g., ISO, IEC for medical electrical equipment), and the performance characteristics of the legally marketed predicate device.
• The "experts" involved would be the manufacturer's engineers, quality assurance personnel, and regulatory specialists who designed, tested, and evaluated the device against these objective criteria. Their qualifications would stem from their professional expertise in medical device development, testing, and regulatory requirements.

4. Adjudication Method for the Test Set

• Adjudication methods like "2+1" or "3+1" are typically used in clinical studies involving human observers (e.g., radiologists interpreting images) where consensus or a tie-breaking mechanism is needed to establish a "true" label.
• This submission describes nonclinical engineering testing. Therefore, such adjudication methods are not applicable. The results of the tests (e.g., pressure measurements, acoustic levels, vibration, thermal performance, software function) are objective, quantitative data compared against predefined specifications and predicate performance.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

• No, an MRMC comparative effectiveness study was not done.
• MRMC studies are clinical studies designed to evaluate the diagnostic performance of human readers, often comparing performance with and without an AI-assisted device.
• This 510(k) submission is for an alternate component (air compressor) of a ventilator, not a diagnostic AI device. The submission explicitly states: "The modifications made to the Engström ventilator did not require clinical testing."

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

• This question is framed for AI/algorithm-based devices. The Engström Carestation and Engström Pro are physical medical devices (ventilators) with microprocessor control, not standalone AI algorithms.
• The "standalone performance" of the EVair compressor itself was evaluated during its design and verification to meet engineering specifications (acoustics, vibration, thermal dissipation) and then its integrated performance with the ventilator system was verified. This can be considered the equivalent of a "standalone" functional test for the component.

7. The Type of Ground Truth Used

• For this nonclinical submission, the ground truth is based on:
  • Engineering Specifications: Detailed technical requirements for component performance (e.g., pressure ranges, flow rates, alarm thresholds, acoustic limits, vibration levels, thermal profiles).
  • Regulatory Standards: Compliance with relevant national and international standards for medical devices, particularly continuous ventilators (e.g., 21 CFR 868.5895, ISO, IEC standards).
  • Predicate Device Performance: The demonstrated safe and effective performance of the previously cleared predicate device (Engstrom Ventilator K111116 and its EVair03 compressor). The new EVair compressor was evaluated against the functional performance of the EVair03.

8. The Sample Size for the Training Set

• This question is relevant for machine learning or AI models.
• Not applicable. This submission is for a physical medical device and its component, not an AI model requiring a training set.

9. How the Ground Truth for the Training Set was Established

• Not applicable, as there is no training set for an AI model in this submission.

The Datex-Ohmeda 7900 Anesthesia Ventilator is used in the Avance Anesthesia Systems. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber. bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is regulated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices. Ventilator modes for the device include Volume Control Ventilation (VCV), Pressure Control Ventilation (PCV) (optional), Synchronized Intermittent Mandatory Ventilation/Pressure Support (SIMV/PSV) (optional), Pressure Support Ventilation (PSVPro) (optional), Synchronized Intermittent Mandatory Ventilation-Pressure Control (SIMV-PC) (optional), Pressure Control Ventilation-Volume Guaranteed (PCV-VG) (optional), Constant Positive Airway Pressure/Pressure Support Ventilation (CPAP/PSV), Pressure Control Ventilation-Volume Guaranteed with Pressure Support Ventilation (SIMV PCV-VG) (optional), and Volume Control Ventilation Mode for Cardiac Bypass Mode (optional). Ventilator parameters and measurements are displayed on the system display unit.

Several frame configurations are available, including one that allows for the physical integration of the GE Monitor Series (cleared Carescape B850 via K092027 and B650 cleared on K102239). These configurations also provide cable management solutions such that the necessary connections from the monitor display unit to the monitor are hidden within the Avance frame. Additional configurations allow for the mounting of various patient monitors on the top shelf of the Avance.

The provided text is a 510(k) summary for the GE Datex-Ohmeda Avance CS2 Anesthesia System. It details the device's description, intended use, and a comparison to a predicate device. However, it explicitly states that no clinical testing was required or conducted for the modifications made to this version of the device.

Therefore, the document does not contain the information requested in your prompt regarding acceptance criteria and the study that proves the device meets them, as these are typically derived from clinical or comprehensive performance studies which were not performed in this case.

Specifically, the document states:

• "The modifications made to the GE Datex-Ohmeda Avance CS2 did not require clinical testing. The functionality of the modified features was completely evaluated by performing nonclinical tests of design verification and validation testing."

Without a clinical study or a study specifically designed to establish performance against acceptance criteria, I cannot fill out the requested table or provide details on sample sizes, expert involvement, ground truth establishment, or comparative effectiveness.

The only "testing" mentioned is nonclinical verification and validation testing, which includes:

• Risk Analysis
• Requirements Reviews
• Design Reviews
• Testing on unit level (Module verification)
• Integration testing (System verification)
• Performance testing (Verification)
• Safety testing (Verification)
• Simulated use testing (Validation)

This nonclinical testing served to confirm that the changes made (primarily updated labeling to include the use of an optional CARESCAPE respiratory module) did not alter the fundamental scientific technology or indications for use, and that the device remained substantially equivalent to its predicate.

Here's an analysis of the provided text regarding acceptance criteria and supporting studies for the GE Datex-Ohmeda Avance CS2 Anesthesia System:

Based on the provided document, the application is for a 510(k) premarket notification, which focuses on demonstrating substantial equivalence to a predicate device rather than undergoing new clinical trials for efficacy. Therefore, much of the information typically requested for acceptance criteria and a deep dive into study design for novel devices is not present or not applicable in this context.

The document explicitly states: "The modifications made to the GE Datex-Ohmeda Avance to create the GE Datex-Ohmeda Avance CS2 did not require clinical testing. The functionality of the modified features was completely evaluated by performing nonclinical tests of design verification and validation testing."

This immediately tells us that there was no standalone clinical study with human patients to prove device performance against specific acceptance criteria in the way one might expect for a new, high-risk device.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and the Reported Device Performance

Given the nature of a 510(k) for an updated device, the "acceptance criteria" are primarily related to meeting specifications, voluntary standards, and demonstrating that the new features do not negatively impact safety and effectiveness compared to the predicate device. There isn't a table of specific clinical performance metrics (e.g., accuracy of a diagnostic feature, rates of successful treatment) with corresponding target values and achieved results reported in this summary.

Acceptance Criteria (Implied from 510(k) process and text):

2. Sample Size Used for the Test Set and the Data Provenance

• Test Set Sample Size: Not applicable in the context of human clinical data for this specific device. The testing involved "nonclinical tests of design verification and validation testing," including unit-level testing, integration testing, performance testing, safety testing, and simulated use testing. These are not typically quantified with "sample sizes" in the same way as human subject studies; rather, they involve testing various components, configurations, and scenarios.
• Data Provenance: Not applicable as no clinical data from patients was used. The data provenance would be from internal engineering and quality testing (e.g., lab test data, simulated environment data).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

• Not applicable. Since no clinical testing was performed and no ground truth was established from patient data, there's no mention of experts establishing a ground truth for a test set in a diagnostic or outcome-based scenario. The "ground truth" for nonclinical testing would be engineering specifications and functional requirements.

4. Adjudication Method for the Test Set

• Not applicable. There was no clinical test set requiring adjudication in the context of human data. Adjudication methods (like 2+1, 3+1) are typically used for resolving disagreements among human readers/experts in interpreting clinical data.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not applicable. This device is an anesthesia system, not an AI-powered diagnostic or assistive tool for human readers. Therefore, an MRMC comparative effectiveness study involving human readers and AI assistance would not be relevant and was not performed.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done

• Not applicable. This is an anesthesia machine, not an algorithm-only device. Its performance is inherent in its hardware, software, and integrated components, designed to operate with a medical professional as the "human in the loop" administering anesthesia.

7. The Type of Ground Truth Used

• For Nonclinical Testing: The ground truth would be based on engineering specifications, design requirements, and established performance benchmarks derived from the predicate device and relevant industry standards.
• For Substantial Equivalence: The ultimate "ground truth" for the 510(k) process is the safety and effectiveness profile of the predicate device (GE Datex-Ohmeda Avance, K112722). The new device must demonstrate it meets this same standard.

8. The Sample Size for the Training Set

• Not applicable. Given the device type and the absence of clinical studies, there is no mention of a "training set" in the context of machine learning. The testing performed (verification and validation) is based on engineering principles and quality assurance, not statistical training sets.

9. How the Ground Truth for the Training Set Was Established

• Not applicable, as there was no machine learning training set mentioned.

The provided text is a 510(k) Premarket Notification summary for the GE Datex-Ohmeda Avance Anesthesia System. This document focuses on demonstrating substantial equivalence to previously cleared predicate devices, rather than establishing de novo acceptance criteria and performing a study to prove they are met.

Therefore, the requested information categories concerning acceptance criteria and study design are not directly applicable or present in this type of regulatory submission. The document explicitly states: "The modifications made to the GE Datex-Ohmeda Avance did not require clinical testing."

However, I can extract information related to the non-clinical testing that was performed to support the substantial equivalence claim, which serves as a form of acceptance in the context of a 510(k) submission.

Here's a breakdown of the available information, addressing as many of your points as possible:

Acceptance Criteria and Reported Device Performance

Since this is a 510(k) submission for an updated device, the "acceptance criteria" are implicitly tied to demonstrating that the updated device performs equivalently or better than the predicate devices and meets its own verified specifications. The document does not provide a table for specific performance metrics and their acceptance ranges. Instead, it describes a robust non-clinical testing approach.

Study Details (Non-Clinical)

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not specified as a number of "samples" in the clinical sense. The testing involved various modules, integrated systems, and simulated use of the device.
   • Data Provenance: Not explicitly stated (e.g., country of origin, retrospective/prospective). However, the testing was conducted internally by the manufacturer (Datex-Ohmeda Inc.) as part of their development process. It is by nature "prospective" in the sense that the tests were designed and executed to evaluate the new device's modifications.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

   • Number of Experts: Not specified. This type of non-clinical engineering validation typically involves internal engineers, quality assurance personnel, and potentially subject matter experts who understand anesthesia systems.
   • Qualifications of Experts: Not specified, but implied to be qualified technical and engineering personnel involved in the device's design, development, and testing at Datex-Ohmeda.

3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

   • Adjudication Method: Not applicable. This concept pertains to clinical studies where independent reviewers agree on ground truth. In non-clinical engineering testing, "adjudication" is managed through formal test protocols, defect tracking, and review processes by the development and quality teams.

4. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • MRMC Study: No. This is not an AI-assisted diagnostic device, but an anesthesia system. Therefore, MRMC studies are not relevant. This document explicitly states: "The modifications made to the GE Datex-Ohmeda Avance did not require clinical testing."

5. If a standalone (i.e., algorithm only without human-in-the loop performance) was done:

   • Standalone Performance: The non-clinical testing evaluates the device's inherent performance characteristics, including its software logic and hardware functionality, in a standalone manner (i.e., its ability to perform its functions as designed without direct human intervention in the moment of testing, though human users operate the system during its intended use). The testing verifies that the "algorithm only" (software) performs as specified.

6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

   • Ground Truth: For non-clinical engineering validation, the "ground truth" is defined by the device's design specifications, industry standards, and regulatory requirements. The device is tested against these predefined criteria to ensure it performs as intended and safely.

7. The sample size for the training set:

   • Training Set Sample Size: Not applicable. This is not an AI/machine learning device that requires a training set.

8. How the ground truth for the training set was established:

   • Ground Truth for Training Set: Not applicable, as there is no training set for an AI/ML model.

In summary: The GE Datex-Ohmeda Avance Anesthesia System underwent a non-clinical verification and validation process. The "acceptance criteria" were met through demonstrating compliance with design specifications, software validation, risk analysis, and adherence to voluntary standards. No clinical studies were deemed necessary due to the nature of the modifications and the substantial equivalence claim.

The provided text describes a 510(k) premarket notification for the GE Datex-Ohmeda Engström Ventilator family (Engström Carestation and Engström Pro). This submission is for an updated version of an existing device, primarily involving software changes.

Here's an analysis of the acceptance criteria and study information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The submission does not explicitly provide a table of acceptance criteria with specific performance metrics (e.g., accuracy, sensitivity, specificity) for the device's functions. Instead, it focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing and verification.

However, the general acceptance criteria for this type of submission are implied through the testing methods described:

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size for Test Set: Not explicitly stated. The text mentions "Testing on unit level," "Integration testing," "Performance Testing (Verification)," and "Safety Testing (Verification)" but does not specify the number of devices or scenarios used for these tests.
• Data Provenance: The testing appears to be conducted in-house by GE Healthcare/Datex-Ohmeda Inc. as part of their development and verification process. The data is retrospective in the sense that it's based on internal testing conducted on the device prior to submission, rather than prospective clinical trials. There is no mention of data origin by country.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. This submission is for a ventilator, and the testing described is primarily engineering verification and validation against technical specifications and predicate device performance. It does not involve interpretation of medical images or diagnostic outputs that would require clinical expert "ground truth" establishment in the way a diagnostic AI device would. "Simulated Use/User Requirements Testing (Validation)" was performed, implying user involvement, but the number and qualifications of these users/experts are not specified, nor is their role in establishing a "ground truth" defined in the typical diagnostic context.

4. Adjudication Method for the Test Set

Not applicable. As noted above, the testing is against technical specifications and predicate device performance, not against expert-adjudicated ground truth.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

No MRMC comparative effectiveness study was done. The text explicitly states: "The modifications made to the Engstrom ventilator did not require clinical testing."

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

The device itself is a standalone medical device (a ventilator), not an algorithm intended for diagnostic interpretation. The software updates were evaluated for their standalone functionality as part of the ventilator system. The non-clinical tests verified and validated the "safety and functionality" of the ventilator with the software changes.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is its adherence to:

• Technical Specifications: The device's design specifications for ventilation parameters, safety features, alarm conditions, etc.
• Predicate Device Performance: The established safety and effectiveness of the previously cleared Engstrom Ventilator (K093886) and Hamilton G5 Ventilator (K070513).
• Applicable Standards: Compliance with relevant medical device standards (e.g., electrical safety, electromagnetic compatibility).

8. The Sample Size for the Training Set

Not applicable. This document describes a medical device (ventilator) with software updates, not an AI/ML algorithm that requires a "training set" in the machine learning sense. The software updates were based on "customer feedback" and "minor changes to bring the product in line with current specifications," but this is not equivalent to a supervised learning training process.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there was no AI/ML training set in the context described by the question.

Ask a specific question about this device

The GE Datex-Ohmeda Aisys Anesthesia System is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients (neonatal, pediatric, adult). The device is intended for volume or pressure control ventilation. The Aisys is not suitable for use in a MRI environment.

The GE Datex-Ohmeda Aisys is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients (neonatal, pediatric, adult). It represents one of the systems in a long line of products based on the Datex-Ohmeda Excel. Aestiva, Aespire, and Avance Anesthesia Systems. It is to be used only by trained and qualified medical professionals.

The GE Datex-Ohmeda Aisys Carestation supplies set flows of medical gases to the breathing system using electronic gas mixing. Gas flows are selected by the user using the keypad and rotary controller on the main display unit and then displayed as electronic flow indicators on the svstem display unit. The Aisvs is equipped with a pneumatic back-up O2 delivery system and traditional flow tube, as well. A large selection of frames, gases, and vaporizers are available to give the user control of the system configuration. The Aisys is also available in a pendant model. It is available with two or three gases, and up to three cylinder connections. All models have 02. The Aisys comes with up to two optional gases (air, N2O). Safety features and devices within the Aisys are designed to decrease the risk of hypoxic mixtures and complete power or sudden gas supply failures. The Aisys system is available with optional integrated respiratory gas monitoring. When supplied as an option, the integrated respiratory gas monitoring is provided via the Datex-Ohmeda M-Gas Module (M-CAiO and M-CAiOV software revision 3.2 and above cleared via K001814) and E-Gas Module (E-CAiOVX software revision 4.5 and above cleared via K051092) which can be physically integrated into the Aisys, receive electronic power from the Aisys and communicate measured values to the Aisys for display on the system display unit.

The anesthetic agent delivery for the Aisys is controlled via an anesthesia computer through user input from the central display. The vaporization technology is based upon the electronic vaporizer cleared as part of the Datex-Ohmeda Anesthesia Delivery Unit (ADU) cleared via K973985. An Aladin cassette (also cleared as part of K973895) or Aladin 2 is inserted into the active cassette bay. The cassette holds the agent to be delivered - Halothane, Enflurane, Isoflurane, Desflurane or Sevoflurane. Agent is delivered as a percent volume/volume. The Aisvs is designed to allow only one active cassette at a time. Per the user input into the main display, valves within the active cassette bay will open and allow agent to be delivered. The agent is mixed with gas from the FGC unit. After mixing, the combination of gases and agent is delivered to the breathing system and then on to the patient.

The Datex-Ohmeda 7900 Anesthesia Ventilator is used in the Aisys Anesthesia System. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber, bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple and secure setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is requlated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices. Ventilator modes for the device include Volume Control Ventilation (VCV), Pressure Control Ventilation (PCV) (optional), Synchronized Intermittent Mandatory Ventilation/Pressure Support (SIMV/PSV) (optional), Pressure Support Ventilation (PSVPro) (optional), Synchronized Intermittent Mandatory Ventilation-Pressure Control (SIMV-PC) (optional), Pressure Control Ventilation-Volume Guaranteed (PCV-VG) (optional) and Constant Positive Airway Pressure/Pressure Support Ventilation (CPAP/PSV). Ventilator parameters and measurements are displayed on the system display unit.

The provided text describes a premarket notification (510(k)) for the GE Datex-Ohmeda Aisys Anesthesia System. This document focuses on demonstrating substantial equivalence to a predicate device, rather than providing detailed acceptance criteria and a study report as would be found for a novel device.

The submission states that the modifications made did not require clinical testing, and the functionality was evaluated through nonclinical tests of design verification and validation testing. Therefore, the information requested regarding acceptance criteria and a study proving the device meets those criteria for a new clinical claim is not present in this document.

However, I can extract information about the type of testing performed and the conclusion regarding substantial equivalence.

Here's a breakdown of the available information based on your request, with an emphasis on what is not present:

1. A table of acceptance criteria and the reported device performance

• Not explicitly provided in the document. The document states "The GE Datex-Ohmeda Aisys has been thoroughly tested through verification of specifications and validation, including software validation," but it does not list specific, quantitative acceptance criteria or corresponding reported performance metrics for clinical efficacy or diagnostic accuracy.
• The overall "acceptance criteria" for this 510(k) submission is demonstrating substantial equivalence to predicate devices. The conclusion states: "The performance data demonstrates the device is substantially equivalent to the predicates."

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Not applicable/Not provided. No clinical test set or patient data is mentioned as the basis for the 510(k) in this document. The testing was non-clinical.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Not applicable/Not provided. No clinical ground truth was established as no clinical testing was performed for this 510(k). Non-clinical testing would involve engineering and quality assurance experts.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable/Not provided. No clinical test set or adjudication method is mentioned.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not applicable. This device is an anesthesia system, not an AI-assisted diagnostic tool. No MRMC study was performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• Not applicable. This device is an anesthesia system. The software updates relate to user interface, control of gas delivery, and ventilator modes, not standalone algorithmic performance in a diagnostic context. "Standalone" performance testing would be more relevant to the device's functional operation (e.g., accuracy of gas delivery, ventilator parameters) which was covered by non-clinical verification and validation.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• Not applicable/Not provided in a clinical sense. For the non-clinical testing, the "ground truth" would be the device's technical specifications and established engineering standards, against which its performance was verified and validated.

8. The sample size for the training set

• Not applicable/Not provided. This document is not describing a machine learning or AI model that requires a training set in the conventional sense. The "software updates" are likely improvements to existing control algorithms and user interface logic.

9. How the ground truth for the training set was established

• Not applicable/Not provided. As above, no training set for a machine learning model is mentioned.

Summary of what is present regarding testing:

The document states:

• Reason for 510(k): Updates to the software for the GE Datex-Ohmeda Aisys Anesthesia System, introducing several new features (e.g., pediatric improvements, new ventilation mode CPAP/PSV with backup breaths, lung mechanics procedure options, UI enhancements).
• Basis for Substantial Equivalence: Comparison to legally marketed predicate devices (GE Datex-Ohmeda Aisys (K090233) and GE Datex-Ohmeda Engstrom ventilator (K093886)). No changes to intended use or fundamental scientific technology.
• Testing Performed:
  • Nonclinical Testing: "thoroughly tested through verification of specifications and validation, including software validation."
  • Quality Assurance Measures applied:
    • Risk Analysis
    • Requirements Reviews
    • Design Reviews
    • Testing on unit level (Module verification)
    • Integration testing (System verification)
    • Performance testing (Verification)
    • Safety testing (Verification)
    • Simulated use testing (Validation)
  • Clinical Testing: "The modifications made to the GE Datex-Ohmeda Aisys did not require clinical testing. The functionality of the modified software features were completely evaluated by performing nonclinical tests of design verification and validation testing."
• Conclusion: The performance data (nonclinical) demonstrates the device is substantially equivalent to the predicates, with no new questions of safety and effectiveness.

In essence, this 510(k) leverages the predicate devices' established safety and effectiveness, and for the software updates, relies on rigorous non-clinical engineering verification and validation testing rather than new clinical trials or performance studies against specific acceptance criteria for a novel claim.

The GE Datex-Ohmeda Aisys Anesthesia System is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. The device is intended for volume or pressure control ventilation. The Aisys is not suitable for use in a MRI environment.

The GE Datex-Ohmeda Aisys is intended to provide general inhalation anesthesia and ventilatory support to a wide range of patients. It represents one of the systems in a long line of products based on the Datex-Ohmeda Excel, Aestiva, Aespire, and Avance Anesthesia Systems. It is to be used only by trained and qualified medical professionals.

The GE Datex-Ohmeda Aisys Carestation supplies set flows of medical gases to the breathing system using electronic gas mixing. Gas flows are selected by the user using the keypad and rotary controller on the main display unit and then displayed as electronic flow indicators on the system display unit. The Aisys is equipped with a pneumatic back-up O2 delivery system and traditional flow tube, as well. A large selection of frames, gases, and vaporizers are available to give the user control of the system configuration. The Aisys is also available in a pendant model. It is available with two or three gases, and up to three cylinder connections. All models have O2. The Aisys comes with up to two optional gases (air, N2O). Safety features and devices within the Aisys are designed to decrease the risk of hypoxic mixtures and complete power or sudden gas supply failures. The Aisys system is available with optional integrated respiratory gas monitoring. When supplied as an option, the integrated respiratory gas monitoring is provided via the Datex-Ohmeda M-Gas Module (M-CAiO and M-CAiOV software revision 3.2 and above K# 001814) and E-Gas Module (E-CAiOVX cleared via K051092) which can be physically intecrated into the Aisys, receive electronic power from the Aisys and communicate measured values to the Aisys for display on the system display unit.

The anesthetic agent delivery for the Aisys is controlled via an anesthesia computer through user input from the central display. The vaporization technology is based upon the electronic vaporizer cleared as part of the Datex-Ohmeda Anesthesia Delivery Unit (ADU) cleared via K973985. An Aladin cassette (also cleared as part of K973895) or Aladin 2 is inserted into the active cassette bay. The cassette holds the agent to be delivered - Halothane, Enflurane, Isoflurane. Desflurane or Sevoflurane. Agent is delivered as a percent volume/volume. The Aisys is designed to allow only one active cassette at a time. Per the user input into the main display, valves within the active cassette bay will open and allow agent to be delivered. The agent is mixed with gas from the FGC unit. After mixing, the combination of gases and agent is delivered to the breathing system and then onto the patient.

The Datex-Ohmeda 7900 Anesthesia Ventilator is used in the Aisys Anesthesia System. It is a microprocessor based, electronically controlled, pneumatically driven ventilator that provides patient ventilation during surgical procedures. The 7900 ventilator is equipped with a built-in monitoring system for inspired oxygen, airway pressure and exhaled volume. Sensors in the breathing circuit are used to control and monitor patient ventilation as well as measure inspired oxygen concentration. This allows for the compensation of compression losses, fresh gas contribution and small leakage in the breathing absorber, bellows and system. User setting and microprocessor calculations control breathing patterns. The user interface keeps settings in memory. The user may change settings with a simple and secure setting sequence. A bellows contains breathing gasses to be delivered to the patient. Positive End Expiratory Pressure (PEEP) is requlated electronically. Positive pressure is maintained in the breathing system so that any leakage that occurs is outward. An RS-232 serial digital communications port connects to and communicates with external devices. Ventilator modes for the device include Volume Mode, Pressure Control Mode, Pressure Support with Apnea Backup Mode (Optional) and Synchronized Intermittent Mandatory Ventilation (SIMV) Mode (Optional). Ventilator parameters and measurements are displayed on the system display unit.

The system display unit is mounted to an arm on the top shelf of the Aisys. The arm is counter balanced and capable of moving vertically and/or horizontally, and also tilting the display, enabling the user to position the display to the most advantageous viewing position. The arm length is limited such that the display position is always within the footprint of the Aisys frame. The arm also supports the mounting of additional display units for a variety of patient monitors.

Several frame configurations are available, including one that allows for the physical integration of the Datex-Ohmeda S/5 Anesthesia Monitor (most recently cleared via K030812). This configuration also provides cable management solutions such that the necessary connections from the monitor display unit to the monitor are hidden within the Aisys frame. An additional ootion allows the S/5 AM to be linked to the power supply of the Aisys such that when the Aisys is turned on, the S/5 AM is also turned on. Additional configurations allow for the mounting of various patient monitors on the top shelf of the Aisys.
