The Equivital™ Vital Signs Physiological Monitor is an ambulatory multiparameter vital signs telemetry device intended for monitoring of adults (16 - 65years) in hospital care facilities, the home, workplace, and alternate care settings.

The device consists of a chest belt harness and a body worn electronics module (SEM) supported by the chest belt).

The device collects and transmits ECG data and rate, respiration data and rate, skin temperature, body orientation and motion.

The monitor is indicated for use as a general patient monitor, to provide physiological information as part of an occupational welfare monitoring system, and for general research and performance measurement purposes.

The Equivital™ Vital Signs Physiological Monitor comprises two components:

i) A chest belt containing skin electrodes and an expansion sensor

ii) A battery powered electronics module which connects directly to the chest belt and which acts to record, digitise and transmit the physiological information wirelessly to a receiving display device.

The device offers continuous monitoring of two views of the user's heart electrical activity (ECG) and respiratory breathing frequency inferred from thoracic cavity movement and uses this data to derive a Heart Rate and a Breathing Effort Rate.

The sensor also provides the following information:

• ECG and Respiration physiological waveforms. .
• an indication of the user's activity level (none, low or high) derived from a movement . detection sensor.
• . Body orientation.
• Chest skin surface temperature. .
• alternate secondary measurement of heart rate based on the detection of the user's R . wave using a separate hardware processing function.
• indications and alerts if physiology exceeds predefined boundaries. .

The device offers two variants for the wireless interface: a low power radio interface designed for military applications and a general purpose interface using Bluetooth™ technology.

The device offers two battery power options for the user, rechargeable or primary disposable cells.

The wireless data provided by the sensor may be viewed using a standalone PC based viewing application, or integrated into third party monitoring applications.

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.

1. Table of Acceptance Criteria and Reported Device Performance

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.
