The GE Datex-Ohmeda Engström Carestation and Engström Pro are microprocessor based, electronically controlled, pneumatically driven ventilators that include integrated FiO2, airway pressure, spirometry and volume monitoring and an Aerogen Aeroneb Pro nebulizer control board.

The ventilator consists of two main components: a display and a ventilator unit. The display allows the user to interface with the system and control settings through use of soft keys on the display, a com wheel, and a resistive touch screen. The Engström Carestation also includes a module bay that allows the integration of various Datex-Ohmeda patient monitoring modules with the ventilator.

The user interface for control of nebulization is provided via the ventilator display unit. The standard nebulizer board is provided with both the Engström Carestation and Engström Pro variants. Users have the option to configure the system to use an external pneumatic nebulizer in place of the standard nebulizer.

The optional medical air compressor is intended for use as an accessory to provide a dry, filtered, breathable compressed air supply. The compressor is installed in the base of the ventilator cart. The compressor is powered from AC mains only. A source of compressed oxygen is required to be connected to Engström Carestation/Engström Pro equipped with the optional compressor. The use of an integrated air compressor was first cleared in K050597.

Optional accessories common to both Engström Carestation and Engström Pro include a trolley/cart, integrated air compressor, support arm, humidifier and water trap mounting brackets, and a data capture accessory. Additional optional accessories specific to the Engström Carestation include airway modules, intratracheal pressure sensor, auxiliary electrical outlets, and module bay. Optional functionality specific to the Engström Carestation includes integrated respiratory gas monitoring, capabilities to measure SpiroDynamics via a GE supplied intratracheal pressure sensor in patients using sized 6.5 tracheal tubes and larger, and calculation of functional residual capacity of mechanically ventilated patients using Nitrogen Wash In/Wash Out method. The integrated respiratory gas monitoring is provided via the Datex-Ohmeda Gas Modules, M-C. M-COV. M-COVX, M-CaiO, M-CAiOV, M-CAiOVX, rev 3.2 software and higher (K001814), E-CO, E-COV, E-COVX, E-CAiO, E-CAiOV, E-CAiOVX (K051092), or M-Mini-CO2 Module (K023454) or E-MiniC module (K052582) which are physically integrated into the Engström Carestation, receive electronic power from the Engström Carestation and communicate measured values to the Engström Carestation for display on the system display unit.

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 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.

   • Data Provenance: Not applicable for clinical data. The testing was non-clinical, likely performed internally by the manufacturer during design verification and validation.

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. Ground truth, in a clinical sense, was not established as there was no clinical testing. For non-clinical specification verification, the "ground truth" would be the engineering design specifications and the requirements of the standards themselves, verified by engineers and quality personnel.

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

   • Not applicable. There was no clinical test set requiring adjudication.

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:

   • No. This is a ventilator device, not an AI diagnostic or assistance tool for human "readers." The modifications were to ventilation modes and hardware variants for an established device type.

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

   • Not applicable as this is a medical device (ventilator), not an algorithm or AI system in the typical sense. Its performance is inherent to its mechanical and software operation.

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

   • For the non-clinical testing, the "ground truth" was compliance with established engineering specifications and international safety and performance standards for medical electrical equipment and critical care ventilators.

8. The sample size for the training set:

   • Not applicable. As no clinical testing was done, there was no clinical training set. For software development and verification, there would have been internal testing and validation processes, but these don't typically involve "training sets" in the machine learning sense.

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

   • Not applicable.

In summary, the 510(k) submission for the Engström Ventilator relies on non-clinical verification and validation against established engineering specifications and international standards to demonstrate substantial equivalence to predicate devices. It explicitly states that clinical testing was not required for the modifications made.

This document is a 510(k) summary for the GE Datex-Ohmeda Engstrom Carestation, a continuous ventilator. The provided text does not contain information about acceptance criteria or a study proving the device meets acceptance criteria in the way medical device effectiveness studies for AI/software devices typically do.

Instead, this document focuses on demonstrating substantial equivalence to predicate devices and compliance with voluntary standards for medical electrical equipment.

Therefore, many of the requested sections (e.g., sample size for test set, number of experts, adjudication method, MRMC study, ground truth type and training set details) are not applicable or not provided in this type of regulatory submission for a physical medical device like a ventilator.

Here's a breakdown based on the information provided in the document:

1. Table of Acceptance Criteria and Reported Device Performance

This document does not present acceptance criteria in terms of specific performance metrics (like sensitivity, specificity, accuracy) or a comparative performance study against a defined benchmark. Instead, the "acceptance criteria" for a traditional device like this ventilator are implicitly met by:

• Substantial Equivalence: The primary "acceptance" is that the device is substantially equivalent to legally marketed predicate devices.
• Compliance with Voluntary Standards: The device's design and testing demonstrate compliance with recognized industry standards.

• GE Datex-Ohmeda Engstrom Carestation (K051895, K060862)

Study Proving Device Meets Acceptance Criteria:

The document states: "The GE Datex-Ohmeda Engström Carestation has been validated through rigorous testing that, in part, supports the compliance of GE Datex-Ohmeda Engström Carestation to the standards listed above."

This "rigorous testing" would likely include:

• Bench testing: To verify technical specifications and performance against design requirements and standards (e.g., airflow accuracy, pressure control, alarm functionality).
• Electrical safety and EMC testing: To comply with UL 2601, EN/IEC 60601-1, and EN/IEC 60601-1-2.
• Software verification and validation: To ensure the microprocessor-based control system functions as intended.
• Materials compatibility testing: For components in contact with gases or patients.

However, the specific details regarding the methodology, results, or quantitative metrics of these internal validation tests are not disclosed in this 510(k) summary. These details would be contained within the full 510(k) submission, which is not publicly available.

Due to the nature of this submission (a 510(k) for a physical ventilator, not an AI/software device), the following items are largely not applicable or not provided in this public summary:

2. Sample size used for the test set and the data provenance: Not applicable in the context of device performance claims made via standards compliance and substantial equivalence to predicate devices. Testing would involve engineering validation and verification, not a clinical "test set" in the sense of patient data for an algorithm.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for a ventilator's physical performance is primarily against engineering specifications and industry standards, not expert clinical interpretation of data.

4. Adjudication method for the test set: Not applicable.

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 is for a physical ventilator, not an AI-assisted diagnostic or therapeutic tool for human readers.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This is for a physical ventilator.

7. The type of ground truth used: For a physical device, the "ground truth" would be established by:
* Engineering specifications and design requirements: Ventilator output (pressure, volume, flow) measured against intended values.
* Reference standards and calibrated equipment: For measuring performance parameters.
* Physiological models: For testing performance under simulated patient conditions.
* Clinical consensus on safety parameters: Ensuring the device operates within safe physiological ranges.

8. The sample size for the training set: Not applicable. This is not an AI/ML device that requires a training set.

9. How the ground truth for the training set was established: Not applicable.

Here's an analysis of the provided text regarding the GE Datex-Ohmeda Engstrom Carestation:

Important Note: The provided document is a 510(k) summary and FDA clearance letter. It mainly focuses on establishing substantial equivalence to a previously cleared device, not on presenting novel clinical study results with acceptance criteria in the way you might expect for a new, non-substantially equivalent device or a software as a medical device (SaMD). Therefore, many of your requested items, particularly those related to detailed study methodologies, sample sizes for training/test sets, expert ground truth, and comparative effectiveness, are not explicitly present or applicable in this type of submission.

The "study that proves the device meets the acceptance criteria" in this context refers to the rigorous testing mentioned to support compliance with voluntary standards, which is a key part of demonstrating substantial equivalence for hardware devices like ventilators. It's not a clinical trial comparing performance against a clinical endpoint for a diagnostic device.

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

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size: Not specified in the provided document. The 510(k) summary states "rigorous testing," which would typically involve engineering and performance testing on the device itself, but specific sample sizes of devices or test conditions are not detailed. This is a hardware device, not a diagnostic algorithm; thus, "test set" in the common AI/ML sense doesn't apply directly.
• Data Provenance: Not applicable in the traditional sense for a hardware ventilator. The testing would be conducted in a laboratory or simulated environment, not on a "data set" originating from patients in a specific country. This is a device performance summary, not a data-driven algorithm performance summary.

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

• Not applicable/Not specified. For a hardware ventilator, "ground truth" is typically established by physical measurements, engineering specifications, and established medical standards for ventilator performance, rather than expert consensus on a dataset. Clinical experts would define the requirements but not typically establish "ground truth" for the device's technical performance in a test set.

4. Adjudication Method for the Test Set

• Not applicable/Not specified. Adjudication methods like 2+1 or 3+1 are typically used for establishing ground truth in human-AI studies or for complex diagnostic assessments. For a ventilator's performance testing, the "adjudication" is generally based on objective measurements meeting predetermined engineering specifications and regulatory standards.

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

• No. An MRMC study is relevant for diagnostic imaging or other human-in-the-loop AI/ML applications where human readers' performance is being evaluated with and without AI assistance. This document describes a mechanical ventilator (hardware), not a diagnostic AI system, so such a study would not apply.
• Effect Size of Human Readers Improve with AI vs without AI: Not applicable for this device.

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

• Not applicable in the typical AI/ML sense. While the ventilator itself operates "standalone" in its mechanical functions, the concept of a "standalone algorithm" performance study refers to the isolated performance of a diagnostic or predictive algorithm. The ventilator's performance is intrinsically linked to its hardware and software working together to deliver ventilation. The document states it's a "microprocessor based, electronically controlled, pneumatically driven ventilator," implying algorithms control its function, but their "standalone performance" isn't evaluated separately from the device as a whole.

7. The Type of Ground Truth Used

• Engineering Specifications and Voluntary Standards: The primary "ground truth" for a device like this would be established by objective, measurable engineering specifications (e.g., accuracy of delivered tidal volume, pressure control, alarm threshold accuracy) and compliance with the listed voluntary standards (UL, ASTM, EN/IEC). These standards define acceptable performance ranges and safety requirements.

8. The Sample Size for the Training Set

• Not applicable/Not specified. This is a hardware device being cleared via substantial equivalence, not an AI/ML algorithm requiring a training set in the conventional sense. The "training" of the device refers to its design, development, and testing against pre-defined specifications and standards.

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

• Not applicable/Not specified. As above, the concept of a "training set" ground truth doesn't directly apply here. The "ground truth" for the device's inherent design and functionality would be based on established principles of respiratory physiology, mechanical engineering, electrical engineering, and medical device safety standards.

Here's a breakdown of the acceptance criteria and study information based on the provided document:

Note: The document provided is a 510(k) summary for a medical device (ventilator). These summaries often focus on demonstrating substantial equivalence to a predicate device rather than presenting detailed performance studies with acceptance criteria in the manner one might find for a novel diagnostic algorithm. Therefore, many of the requested data points (like sample size for test sets, number of experts for ground truth, MRMC studies, etc.) are not typically found or disclosed in this type of regulatory filing for this class of device. The "studies" for this device often refer to engineering tests and compliance with recognized standards.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance

• Sample Size for Test Set: Not specified. For this type of device, "testing" primarily refers to engineering verification and validation against performance specifications and recognized standards, not necessarily a "test set" of patient data in the way one would analyze an AI algorithm.
• Data Provenance: Not applicable in the context of clinical patient data. The "study" refers to engineering and quality assurance testing.

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

• Not specified or applicable. The ground truth for a ventilator's performance is typically established by metrological standards, engineering specifications, and functional testing, not by expert clinician consensus on a dataset.

4. Adjudication method for the test set

• Not specified or applicable. Adjudication methods are typically used for subjective clinical interpretations, which is not the primary assessment method for a ventilator's functional performance in this context.

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

• No, an MRMC comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic aids that assist human readers (e.g., radiologists, pathologists). The GE Datex-Ohmeda Engstrom Carestation is a standalone mechanical ventilator; it does not involve human "readers" interpreting output with or without AI assistance in this manner.

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

• Yes, in essence. The "performance" of the ventilator is "standalone" in that its operation (controlling gases, delivering breaths, monitoring) is independent of human interpretation in the way an AI algorithm might be. The device's integrated measurement capabilities (FiO2, airway pressure, spirometry, volume monitoring) perform their functions autonomously. However, this is not a standalone "algorithm" in the context of an AI-driven diagnostic. It is the core function of the device itself.

7. The type of ground truth used

• The "ground truth" for this device's performance is established by:
  • Engineering specifications and design requirements: Ensuring the device can deliver specified volumes, pressures, and modes of ventilation accurately.
  • Compliance with recognized voluntary standards: (e.g., UL 2601, ASTM F1100, EN/IEC 60601 series). These standards define acceptable performance characteristics and safety criteria.
  • Functional tests and calibration: Verifying that components and the overall system operate within specified tolerances.

8. The sample size for the training set

• Not applicable. This device is not an AI algorithm trained on a dataset. Its design and validation rely on engineering principles, component testing, and system-level functional verification.

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

• Not applicable, as there is no "training set" in the context of an AI algorithm.
