The Nihon Kohden TG-980P/TG-980P1 CO2 Sensor Kit is intended for medical purposes to measure the concentration of carbon dioxide in a gas mixture to aid in determining the patient's ventilatory status.

Along with other methods indicated by the physician for medical diagnosis, this device is intended as an indicator of patient carbon dioxide concentration during expiration. The device is intended for use by qualified medical personnel within a hospital, ambulatory care, transport, or any other clinical environment.

The TG-980P and TG-980P1, collectively referred to as TG-980P/TG-980P1, are CO2 Sensor Kits used to measure the concentration of carbon dioxide (CO2 or CO2) during patient expiration. The TG-980P/TG-980P1 is intended for use by qualified medical personnel as an aid for determining patient ventilatory status within a hospital, ambulatory care, transport, or any other clinical environment.

The TG-980P/TG-980P1 CO2 Sensor Kit comprises three main components: a CO2 sensor, an interface connector, and a sensor cable. It utilizes the mainstream measurement method to sample gas directly from the patient's airway and non-dispersive infrared (NDIR) absorption technology to measure CO2 concentration during patient expiration. CO2 gas absorbs infrared light at specific wavelengths, and the amount absorbed is directly related to CO2 concentration. The CO2 sensor is equipped with a light source that generates infrared light. The light passes through an attached Nihon Kohden accessory (except the Thermal Airflow Sensor) through which the expired air flows and is converted by photodetectors to voltage, which is used to calculate CO2 concentration. The calculated digital data is then transmitted and displayed on a connected patient monitor or other device.

The TG-980P/TG-980P1 CO2 Sensor Kit can be connected via the interface connector and used with Nihon Kohden devices for which the operator's manual specifies compatibility with the TG-980P/TG-980P1.

This FDA 510(k) clearance letter pertains to a hardware device (CO2 Sensor Kit) and not an AI/ML software. Therefore, many of the requested criteria regarding AI-specific studies (e.g., sample size for training set, number of experts for ground truth, MRMC study) are not applicable.

However, I can extract the relevant acceptance criteria and details of the non-clinical performance studies conducted for the device.

Central Station is a network device, intended to display, record and print monitored physiological data from Nihon Kohden bedside monitors, telemetry receiver and/or transmitters.

Central Station does not perform any data processing on the data received from the Nihon Kohden compatible devices. When Central Station is connected with the Nihon Kohden bedside monitors and telemetry receivers/transmitters the Central Station can:
• Admit and discharge patients on the Nihon Kohden network.
• Display and manage compatible devices' real-time patient clinical data, vital signs, alarms and waveforms.
• Review and trend data calculated by connected Nihon Kohden devices.
• Store and transfer historical clinical data for the connected systems.
• Print patient data.

Central Station is intended for use in professional medical facilities by trained medical personnel.

Central Station is software only product that is installed on a Commercial Off the Shelf (COTS) Computer.

Central Station displays waveforms data and numerical data from a connected bedside monitor, vital sign telemeter, or multiple patient receiver unit on the screen.

Central Station is a network device, intended to provide remote patient monitoring to medical personnel. Central Station displays a list of measured values and a trend graph. Numerical data and various waveforms are color-coded for each parameter. Central Station also has the function of displaying an alarm.

Alarm indication in Central Station is displayed as a result of a judgment by the bedside monitor, vital sign telemeter, or multiple patient receiver units connected to the Central Station. Central Station itself does not have the function to perform alarm indication judgment.

The provided document is a 510(k) clearance letter for the "Central Station" device. This type of document primarily focuses on establishing substantial equivalence to a legally marketed predicate device rather than detailing specific performance acceptance criteria and study results in the same way as a full clinical trial report or a detailed design validation report would.

The document states:

• "Central Station does not perform any data processing on the data received from the Nihon Kohden compatible devices."
• "Alarm indication in Central Station is displayed as a result of a judgment by the bedside monitor, vital sign telemeter, or multiple patient receiver units connected to the Central Station. Central Station itself does not have the function to perform alarm indication judgment."
• "The results of the substantial equivalence assessment, taken together with non-clinical bench testing, software verification, and validation demonstrate that the Central station does not raise concerns regarding its safety and effectiveness compared to its predicate device and operates in accordance with claimed indications for use."

Given these statements, the "Central Station" device is essentially a display, recording, and communication hub. It does not perform diagnostic algorithms or make independent judgments that would typically necessitate the kinds of detailed performance metrics (like sensitivity, specificity, or reader agreement) that are usually established through extensive multi-reader, multi-case (MRMC) studies with expert ground truth. Its primary function is to accurately display and relay data processed by other Nihon Kohden devices.

Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" for this specific device (Central Station) would primarily revolve around:

• Software Verification and Validation (V&V): Ensuring the software correctly displays, records, and transmits data as designed, and that all features (admit/discharge, trend display, printing, network communication) function as intended without errors.
• Non-Clinical Bench Testing: Confirming interoperability with compatible devices, accuracy of data display, alarm relay, and network functionality.
• Cybersecurity Compliance: Meeting regulatory requirements for cybersecurity.

The document explicitly states that "The software documentation was prepared following the FDA's 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices' (released June 14, 2023), specifically for an Enhanced Documentation Level." and "Verification testing was conducted at the system integration level to confirm that the device software fulfills its requirements and that safety and security risk mitigations, where applicable, were effective. Additionally, system-level testing was carried out to show that the software addresses user needs. All unit, integration, and system-level tests successfully met the test protocols."

Based on the provided text, it is not possible to extract the specific quantitative performance metrics (like sensitivity, specificity, or effect sizes for human readers) that would be relevant for a device performing complex data processing or diagnostic functions. The document emphasizes substantial equivalence and basic functional verification, not advanced AI/diagnostic performance validation.

However, I can infer the spirit of typical acceptance criteria and how a device like this would be proven to meet them, guided by the information provided.

Inferred Acceptance Criteria and Device Performance for "Central Station"

Given the device's stated function (display, record, print, and relay data without processing it for diagnosis or alarm judgment), the acceptance criteria would focus on functional correctness, data integrity, interoperability, and system reliability, rather than diagnostic accuracy metrics.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size and Data Provenance

• Test Set Sample Size: Not explicitly stated as a "sample size" in the context of patient data for diagnostic algorithms, because the device doesn't perform diagnostic processing. The "test set" for this device would be a collection of test cases covering all functional requirements, interoperability scenarios with different compatible devices, alarm conditions (relayed), data storage limits, network loads, and user interaction flows. The document mentions "system integration level" and "system-level testing" and that "all unit, integration, and system-level tests successfully met the test protocols." This implies a comprehensive set of non-clinical, bench-level tests.
• Data Provenance: Not applicable in the sense of clinical patient data (e.g., from specific countries, retrospective/prospective studies), as the device does not process primary patient data for diagnosis. The data used for testing would be simulated, generated, or derived from compatible Nihon Kohden monitor outputs in a lab setting to verify the Central Station's display and communication functions.

3. Number of Experts and Qualifications for Ground Truth

• Not Applicable in the traditional sense for diagnostic AI. The ground truth for this device's performance would be the expected output based on its functional specifications and the known inputs from the connected Nihon Kohden devices. For example, if a connected monitor transmits an HR of 70 bpm, the ground truth is that the Central Station must display 70 bpm. These "ground truths" are established by engineering design specifications, not human expert consensus on clinical findings.
• Experts Involved: Software engineers, quality assurance engineers, subject matter experts on the physiological monitoring systems, and potentially clinical users for usability and workflow testing. Their qualifications would be in device design, software development, testing, and clinical application.

4. Adjudication Method for the Test Set

• Not Applicable in the context of clinical interpretation adjudication (e.g., 2+1 radiologist consensus). Adjudication in this context would be internal to the software development and testing process:
  • Test Pass/Fail Criteria: Predetermined pass/fail criteria for each test case.
  • Bug/Defect Resolution: Issues found during testing are logged as bugs, investigated by engineers, and resolved, followed by retesting.
  • Verification Sign-off: Test leads or design engineers review test results and formally sign off on the successful completion of verification.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No, not performed for this device. An MRMC study is relevant for AI systems that assist human readers in making diagnostic decisions (e.g., radiologists reading X-rays with AI assistance). The Central Station device does not perform any such diagnostic assistance; it merely displays data from other (likely already cleared) devices. Its function is analogous to a monitor or a remote display unit, not a diagnostic AI.

6. Standalone (Algorithm Only) Performance

• Not Applicable. This device does not have a "standalone algorithm" that performs diagnostic or data processing functions independently. Its function is entirely dependent on receiving data from other compatible Nihon Kohden devices.

7. Type of Ground Truth Used

• Functional Specifications and Truth from Connected Devices: The ground truth for this device is based on its functional design specifications (e.g., "display received data," "store data for X hours," "print Y parameters") and the verified output from the connected Nihon Kohden bedside monitors and telemetry systems. It's about data integrity and display accuracy, not clinical outcomes or pathology.

8. Sample Size for the Training Set

• Not Applicable. This device is described as "software only product" that "does not perform any data processing on the data received," and "Central Station itself does not have the function to perform alarm indication judgment." This strongly implies it is a rule-based or deterministic system, not a machine learning/AI system that requires a "training set" in the common sense (i.e., for learning patterns from data for prediction or classification). Therefore, there is no training set.

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

• Not Applicable. As there is no training set for an AI algorithm, there is no corresponding ground truth establishment process for a training set.

The Nihon Kohden NKV-550 Series Ventilator System is intended to provide continuous ventilation for adult, pediatric and neonatal patients who require invasive or noninvasive respiratory support. The NKV-550 offers mandatory and spontaneous ventilation modes as well as respiratory monitoring. The NKV-550 is intended for use in hospitals and hospital-type facilities, as well as, for in-hospital transportation.

The Nihon Kohden NKV-550 Series Ventilator System consists of a graphic user interface (GUI) and a breath delivery unit (BDU). The GUI allows clinicians to set ventilator control parameters such as tidal volume and inspiratory pressure, to set alarm limits such as high inspiratory pressure alarm, to view monitored numeric values, to view waveform and loops, and to operate various features through the apps. The BDU contains a microprocessor that receives inputs from the electronic system and controls the pneumatic system for breath delivery to the patient. It also provides various alarms, a safety valve, and other design features to maximize patient safety.

I am unable to extract specific acceptance criteria for the Nihon Kohden NKV-550 Series Ventilator System or details of a study proving it meets them. The provided text from the FDA 510(k) Summary primarily focuses on establishing substantial equivalence to predicate devices, rather than detailing a specific performance study with acceptance criteria.

The document states:

• "Performance of the Nihon Kohden NKV-550 Series Ventilator System was demonstrated by the following testing performed in compliance with Design Controls: Software Verification, Device Functionality Testing, Human Factors/Usability Testing, Bench Test Comparison with Reference Device, Risk Management."
• "Summary of Clinical Performance Data: Not Applicable – Clinical performance data was not required to demonstrate substantial equivalence."
• "Performance: Met ISO 80601-2-12 requirements on essential performance of critical care ventilator"

This indicates that the device's performance was evaluated against the general requirements of the ISO 80601-2-12 standard for critical care ventilators and through internal design control processes like software verification and functionality testing, but a standalone study with explicit acceptance criteria and performance metrics for the device itself (beyond meeting the ISO standard) is not detailed in this summary.

Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor details about sample sizes, ground truth establishment, expert involvement, adjudication methods, or MRMC studies, as this information is not present in the provided text.

The CNS-2101 central monitor is a networked multi-patient monitoring system, that is intended to display, record and print monitored physiological data from Nihon Kohden bedside monitors, telemetry receiver and/or transmitters. The CNS-2101 does not perform any data processing on the Nihon Kohden compatible devices. When the CNS-2101 is to connect with the Nihon Kohden bedside monitors and telemetry receivers/transmitters the CNS-2101 can:

• · Admit and discharge patients on the Nihon Kohden network.
• · Display and manage compatible devices' real-time patient clinical data.
• Mimic the alarms of connected devices when a measured parameter falls outside a preset limits or when an arrhythmia is detected.
• · Review and trend data calculated by connected Nihon Kohden devices.
• · Store and transfer historical clinical data for the connected systems.
• · Print patient data.

The CNS-2101 is intended for use in professional medical facilities by trained medical personnel.

The CNS-2101 central monitor is a central monitoring device designed to support medical personnel to provide medical care to multiple patients at the same time. It acquires vital sign data from multiple monitoring devices such as bedside monitors and displays the acquired data such as ECG and pulse rate on the screen as well as informing alarms.

The CNS-2101 can communicate with other devices through a network connection. The CNS-2101 can acquire vital sign data directly from multiple monitoring devices (e.g., bedside monitors) connected to Nihon Kohen Monitoring device network or using multiple patient receivers and transmitters, or by a combination of both methods. The parameters to monitor on the central monitor can be changed as necessary by selecting a monitoring device such as a bedside monitor or transmitter and changing the parameter settings for that device.

The CNS-2101 is designed to be installed in a location outside the patient environment such as a nurse's station for central monitoring.

The provided text is a 510(k) summary for the Nihon Kohden CNS-2101 Central Monitor.

The Nihon Kohden NKV-440 Ventilator System is intended to provide continuous ventilation for adult, pediatric and neonatal patients who require invasive or noninvasive respiratory support. The NKV-440 offers mandatory and spontaneous ventilation modes as well as respiratory monitoring. The NKV-440 is intended for use in hospitals and hospital-type facilities, as well as, for in-hospital transportation.

The NKV-440 is a servo-controlled ventilator that is designed to meet the gas delivery and performance requirements for neonate through adult patients. The NKV-440 design is comprised of two major components, a Breath Delivery Unit (BDU) and a Graphic User Interface (GUI). The GUI allows clinicians to set ventilator control parameters such as PEEP and inspiratory pressure, to set alarm limits such as high inspiratory pressure alarm, to view monitored numeric values, and to view waveforms. The BDU assembly contains a blower and the electronics required to perform breath delivery. Ambient air is taken into the blower and mixed with oxygen which is flow rate controlled by a proportional valve. The mixed gas is provided to the patient. The microprocessor controls the blower and the proportional valve to deliver the pressure and oxygen concentration which are set by the user. It also provides various alarms and other design features to maximize patient safety.

The device is intended for use in near real-time monitoring of routing patient status and alarm events. Next Generation NetKonnect supplements the primary patient monitoring system by providing a forwarding for annunciating and displaying patient alarm events and event related information including vital signs values and waveforms. The system is intended for use on any patients as determined by qualified medical personnel within a hospital or clinical environment.

NGNK is a software product that runs on Microsoft Windows architecture. NGNK will communicate with Nihon Kohden devices by a network connection and through the Gateway. The NGNK is intended to interface the Nihon Kohden monitoring network to annunciate and display patient monitoring information to healthcare providers. The device is intended for use in near real-time monitoring of patient status and alarm events. NGNK supplements the primary patient monitoring system by providing remote monitoring capability, including vital signs, alarms and waveforms.

The provided document describes the FDA 510(k) clearance for the Next Generation NetKonnect device. This device is a software product designed to interface with the Nihon Kohden monitoring network to annunciate and display patient monitoring information to healthcare providers. It is an update to a previously cleared device, NetKonnect Remote Network Extension (K112637).

The document focuses on demonstrating substantial equivalence to the predicate device, rather than proving performance against specific quantitative acceptance criteria for a novel device. The primary changes are updates to the User Interface and support for current 64-bit Windows architectures.

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

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

The document does not specify quantitative acceptance criteria in terms of performance metrics (e.g., sensitivity, specificity, accuracy) for physiological measurements or alarm detection. This is because the device primarily functions as a display and annunciation system for data already processed by the primary patient monitoring system, which itself has established performance.

Instead, the "acceptance criteria" appear to be implicit in demonstrating that the modified device performs its intended functions (displaying vital signs, waveforms, and alarm events) reliably and safely, consistent with its predicate. The "reported device performance" is summarized in a qualitative manner through the non-clinical testing.

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

The document states: "No clinical testing was required or performed since substantial equivalence of the device was supported by the non-clinical testing."

Therefore, there is no clinical test set, sample size, or specific data provenance (country, retrospective/prospective) to report for the performance of the device on patient data. The evaluation was primarily internal engineering and software testing.

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)

Given that no clinical testing was performed and the evaluation relied on non-clinical (software) testing, there were no external experts or "ground truth" derived from patient data for an independent performance evaluation. The "ground truth" for software testing usually refers to specified design requirements and expected outputs, which are internally verified by the manufacturer's engineering team.

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

There was no adjudication method used for a clinical test set, as no clinical testing was performed.

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 MRMC study was performed. The device is not an AI-assisted diagnostic tool that would typically involve human readers and their performance improvement. It is a display and annunciation system.

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

The device itself is software that operates "standalone" in the sense that it processes and displays data from patient monitors. However, its purpose is to complement human monitoring in a clinical environment. The software testing mentioned is effectively a standalone performance evaluation against its design requirements and functional specifications. The specific results of this software testing (e.g., bug reports, pass/fail rates for specific test cases) are not detailed in this summary.

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

For the non-clinical (software) testing, the "ground truth" would be the design specifications and functional requirements of the software. This involves verifying that the software correctly receives, processes, and displays the data as intended, and that the user interface functions as designed, without introducing errors or safety concerns. This type of ground truth is established by the manufacturer during the design and development process.

8. The sample size for the training set

The document does not mention any training set. This is not an AI/machine learning device that typically requires training data. It is a communication and display software.

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

As there is no training set, this question is not applicable.

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

Important Note: The provided document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a predicate device, not necessarily a detailed clinical study report proving performance against novel acceptance criteria. In this specific case, the submission emphasizes that there are no new acceptance criteria because the device (Life Scope PT BSM-1700 Series Bedside Monitor) is being updated to include a "standalone mode," but its underlying technology and performance characteristics are unchanged from its previously cleared version (K213316). Therefore, the "study that proves the device meets the acceptance criteria" largely relies on the prior clearance and non-clinical testing for the updated mode.

1. Table of Acceptance Criteria and Reported Device Performance

Since the document explicitly states there are no new technological changes or safety/performance claims, the acceptance criteria are effectively the performance specifications of the predicate device (K213316). The reported device performance is stated to be "the same" as the predicate.

Study Proving Device Meets Acceptance Criteria

The document states:

• "The device performance and software have not changed from the original submission K213316." (Sections 2.4, 3.4, 4.4, 5.4)
• "For this submission the BSM-1700 Bedside Monitor has been updated to include the standalone mode. There are no specification changes, technological changes or safety and Performance claims. The indications for use and labeling have been updated to include the standalone mode." (Section 6)
• "The Life Scope BSM-1700 Series Bedside Monitor was subjected to tests to electromagnetic, environmental, safety, and performance testing procedures. These tests verified the operation of the device. The software validation tested the operation of the software function of the device, the results confirmed that the device performed within specifications." (Section 6.3 Safety & Performance Tests)

Given this, the "study" is primarily an affirmation that the previously cleared performance for K213316 remains valid, coupled with non-clinical verification and validation testing of the additional "standalone mode" functionality to ensure it operates within the established specifications without altering the core performance characteristics.

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

   • The document does not specify a sample size for a clinical test set in this 510(k) summary. This type of submission relies heavily on non-clinical (bench) testing to confirm performance when significant changes are not made.
   • The data provenance is implied to be from Nihon Kohden's internal testing. The submission is focused on demonstrating substantial equivalence rather than presenting a de novo clinical study with patient data. As such, the data would be laboratory-generated from testing the device.

2. 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 provided because no clinical study requiring expert ground truth establishment for a test set is detailed. The "ground truth" for non-clinical performance would be derived from established engineering and metrological standards and test procedures.

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

   • This is not applicable since the submission focuses on non-clinical performance and engineering validation rather than human reader studies.

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:

   • No, an MRMC comparative effectiveness study was not done. This device is a physiological monitor, not an AI-powered diagnostic tool, and the submission does not mention AI assistance.

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

   • The term "standalone" in the provided document refers to a mode of operation for the BSM-1700 device, where it functions independently without being connected to a core unit. It does not refer to a standalone performance study of an algorithm.
   • However, the performance tests described in Section 6.3 were likely conducted in a "standalone" fashion for the device's functional parameters, meaning the device itself was tested to ensure its outputs (e.g., heart rate, SpO2 accuracy) met specifications. The submission highlights that "The device performance and software have not changed from the original submission K213316," implying that the standalone performance requirements were met by the previous device and confirmed for this update.

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

   • For the non-clinical testing, the ground truth would be based on calibrated reference standards and established measurement methodologies for physiological parameters (e.g., known electrical signals for ECG, certified NIBP simulators, calibrated temperature baths, etc.).
   • No clinical ground truth (like pathology or outcomes data) is described in this submission, as it's not a clinical study.

7. The sample size for the training set:

   • This information is not provided. Medical devices like this (physiological monitors) typically undergo engineering development, verification, and validation testing rather than a "training set" in the machine learning sense. Any underlying algorithms (e.g., for signal processing, arrhythmia detection) would have been developed and validated during earlier stages or for previous clearances.

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

   • Not applicable for this type of device and submission. If any algorithms involved "training," the ground truth would have been established using rigorously collected physiological data and expert annotation/labeling, but this detail is not present in the 510(k) summary.

It describes software modifications to enable compatibility with the Smart Cable NMT Module and Accessories, and updates to the stated Indications for Use.

The document does not contain information about an AI/algorithm-only study, a multi-reader multi-case (MRMC) comparative effectiveness study, or details on ground truth establishment for a training set. The device in question is a physiological monitor, and the software modifications are specifically related to integrating with a neuromuscular transmission (NMT) module and updating intended use statements, not for an AI/CADe (Computer-Aided Diagnosis/Detection) algorithm that would typically require such studies.

Therefore, many of the requested criteria related to AI/algorithm performance and clinical validation studies are not applicable to the information provided in this document.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

The document states that the software modifications do not change the safety, performance of the predicate devices. It refers to integration testing, not a de novo performance study with specific quantifiable acceptance criteria for a new AI algorithm.

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

• Sample Size: Not specified in terms of patient data. The testing mentioned is "software unit testing, integration level testing, and system-level testing" and a "system test... based on the software requirements specification." This suggests internal product testing rather than a separate clinical test set of patient data.
• Data Provenance: Not applicable, as no external clinical data test set is described. The focus is on the integration and functional testing of the software within the device system.

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

• Not applicable. The ground truth, in this context, would be the proper functioning and integration of the software and hardware, verified through engineering and system testing, not through expert reading of medical images or data.

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

• Not applicable. This is typically used in clinical studies for establishing ground truth for AI algorithms, which is not the subject of this 510(k).

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. The document explicitly states: "No clinical tests have been submitted, referenced or relied on in this premarket notification submission for a determination of substantial equivalence." This device is not an AI-assisted diagnostic or therapeutic tool; it's a physiological monitor with updated software for compatibility.

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

• No. This is not an AI algorithm requiring standalone performance evaluation. The "software modification" refers to updates enabling the NMT module to work with the monitoring system.

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

• For the software and system functionality: The ground truth is the predefined technical specifications and expected behavior of the device and its integrated components. This is verified through "software unit testing, integration level testing, and system-level testing."

8. The sample size for the training set:

• Not applicable. There's no machine learning model or AI algorithm described that would require a "training set."

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