    AI/ML Overview

    This document describes the Equivital™ Vital Signs Physiological Monitor EQ02, but it does not contain a detailed study demonstrating its performance against specific acceptance criteria for each measured parameter.

    Instead, the submission focuses on demonstrating substantial equivalence to a previously cleared predicate device (Equivital EQ01) and compliance with relevant safety and electromagnetic compatibility standards.

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


    1. Table of Acceptance Criteria and Reported Device Performance

    This table cannot be fully populated as specific performance acceptance criteria (e.g., accuracy ranges for heart rate, respiration rate, temperature) and the numerical results of studies proving these criteria were met are not explicitly provided in the given text.

    The document states that "Performance measurement and review to the applicable sections of the following standards has been undertaken and successfully demonstrated as recommended by available guidance from the agency." This implies that performance was verified against the requirements of these standards, but the specific numerical acceptance criteria and the device's measured performance against them are not detailed.

    ParameterAcceptance Criteria (from Standards, e.g., ANSI/AAMI EC13)Reported Device Performance (numerical results of testing)
    ECG Heart RateNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency" against ANSI/AAMI EC13
    Respiration RateNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency"
    Skin TemperatureNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency" against ASTM E1965 98 (2009)
    Activity LevelNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency"
    Body OrientationNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency"
    Physiological AlertsNot explicitly stated in document"successfully demonstrated as recommended by available guidance from the agency" against ANSI/AAMI EC13
    SafetyEN60601-1"successfully demonstrated"
    EMCIEC60601-1-2"successfully demonstrated"
    BiocompatibilityISO 10993-1"successfully demonstrated"
    SoftwareEN60601-1-4"meets the requirements"
    EnvironmentalIP67"successfully demonstrated"

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

    This information is not provided in the document. The submission references "Performance measurement and review" and "testing undertaken" but does not detail the methodology, sample sizes, or data provenance for these tests.


    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 provided in the document. The document describes a medical device for physiological monitoring, not a diagnostic imaging or AI device requiring expert ground truth for image interpretation. The "ground truth" for vital signs monitoring would typically come from comparison to a highly accurate reference device or direct physiological measurements, not expert consensus in the same way an AI diagnostic model would.


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

    This information is not provided in the document. Adjudication methods like 2+1 or 3+1 are typically used in studies where human readers are making subjective interpretations (e.g., radiology studies). For a vital signs monitor, the comparison would be against a reference standard or objective measurements, not subjective human interpretations 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, a multi-reader multi-case (MRMC) comparative effectiveness study was not conducted or reported for this device. This is a vital signs monitor, not an AI-powered diagnostic tool, so such a study would not be applicable in this context. The device's function is to collect and transmit physiological data, not to assist human readers in interpreting complex cases.


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

    The device itself is a "standalone" physiological monitor in the sense that it collects and processes data to derive heart rate, respiration rate, and other parameters directly from sensor inputs. The performance claimed (e.g., accurate heart rate calculation) is inherent to its algorithms. However, the document does not report a specific "standalone" performance study in the context of an AI algorithm being evaluated against human performance or ground truth. It refers to performance measurement against standards, which implies the device's accuracy in measuring various parameters.


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

    The document does not explicitly state the specific "ground truth" methods used for the performance evaluations. However, based on the nature of medical device testing for vital signs monitors, the ground truth would typically be established by:

    • Comparison to a gold-standard reference device: For parameters like heart rate, respiration rate, and temperature, laboratories use highly accurate and calibrated reference instruments to provide the "true" value against which the device under test is compared.
    • Direct physiological measurements: In some cases, direct measurements (e.g., manual respiration counts, core body temperature probes) might be used as a reference.

    It would not typically involve expert consensus, pathology, or outcomes data for the primary performance assessment of vital sign accuracy.


    8. The sample size for the training set

    This information is not applicable and not provided. The Equivital™ Vital Signs Physiological Monitor EQ02 is described as a telemetry device and monitor, not an AI/machine learning model that undergoes "training" in the conventional sense with a distinct training set. Its functionality is based on established signal processing and sensor technologies, not adaptive learning from a large dataset.


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

    This information is not applicable and not provided. As stated above, the device does not use a "training set" in the context of machine learning. Its algorithms are likely based on fixed rules and signal processing techniques designed and validated through engineering principles.

    AI/ML Overview

    The provided text describes the Equivital™ Vital Signs Physiological Monitor and its 510(k) summary. However, it does not contain specific acceptance criteria, detailed study designs, or performance results in the format requested. The document lists the standards against which the device was evaluated but does not present the actual results or how those results met specific criteria.

    Therefore, I cannot populate the table or provide detailed answers to many of the questions based solely on the provided text. I will indicate what information is available and what is missing.

    Study that Proves the Device Meets the Acceptance Criteria:

    The document states that "Performance measurement and review to the applicable sections of the following standards has been undertaken and successfully demonstrated as recommended by available guidance from the agency." This implies a series of verification and validation tests were conducted to ensure compliance with the listed standards (EN60601-1, IEC60601-1-2, ISO 10993-1, ANSI/AAMI EC13, ASTM E 112-00, and EN60601-1-4 for software). Additionally, "Additional voluntary testing has been undertaken to the following: General functional test, Environmental Performance Test."

    However, none of the specific study results or methodologies for these tests are described in the provided text. The document acts as a summary for a 510(k) submission, confirming that such testing occurred and was successful, rather than detailing the studies themselves.


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

    • Sample Size: Not specified for any test set.
    • Data Provenance: Not specified. The manufacturer is based in the United Kingdom, but the origin of any test data is not mentioned within the summary.
    • Retrospective or Prospective: Not specified.

    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 specified. The document does not describe the use of human experts for ground truth establishment for performance testing. Performance is noted to be measured against standards, implying instrument-based or standardized reference methods rather than expert consensus on a test set.

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

    • Not applicable/Not specified. The document does not describe a scenario requiring expert adjudication or consensus for ground truth on a test set.

    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, a multi-reader multi-case (MRMC) comparative effectiveness study is not mentioned. The device is a "Vital Signs Physiological Monitor" and does not involve AI assistance for human readers/clinicians, but rather directly measures physiological parameters.

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

    • The device itself is a standalone monitor, meaning its core function is to collect, digitize, and transmit physiological information. The performance measured would inherently be the algorithm/device only for parameters like heart rate, breathing rate, and temperature. The document states "Performance measurement and review to the applicable sections of the following standards has been undertaken and successfully demonstrated," suggesting performance evaluations of the device's output against established standards.

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

    • The implicit ground truth is likely reference measurements from established, validated medical devices or standardized calibration methods as per the requirements of the listed performance standards (e.g., ANSI/AAMI EC13 for cardiac monitors, ASTM E 112-00 for temperature). The document does not mention expert consensus, pathology, or outcomes data as ground truth.

    8. The sample size for the training set

    • Not applicable/Not specified. The document does not provide information about a "training set" as it describes a hardware physiological monitor, not typically a machine learning or AI-driven diagnostic device that undergoes explicit training on a dataset in the way a software algorithm might.

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

    • Not applicable/Not specified, as no training set is mentioned for this device.
