Brief Summary
-----------------
Clinical Investigation Plan: Vital USA SpO2 Accuracy Comparison to Arterial Blood CO-Oximetry Study ID# PR 2019-353, Version: Rev 1, Date: 15 Oct 2019 Study Dates: November 4-5, 2019

Detailed Description
-----------------
An SpO2 accuracy comparison was conducted as part of the final validation of the VitalDetect™ pulse oximetry system. The study was conducted in accordance to Code of Federal Regulations (CFR) for Non-Significant Risk (NSR) investigational studies, following International Standards Organization (ISO) 14155:2011 as appropriate and the pulse oximetry guidelines of ISO 80601-2-61:2017 applicable sections, and Pulse Oximeters - Premarket Notifications Submissions [510(k)s] Guidance For Industry and Food and Drug Administration Staff (issued: March 4, 2013). The purpose of this study was to validate the SpO2 accuracy of the VitalDetect™ pulse oximetry system during non-motion conditions over the range of 70-100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry. It was expected that the Accuracy Root Mean Square (ARMS) performance of the oximetry system would meet the required specification of ARMS of 3.0% or less. A secondary goal was to evaluate the pulse rate performance simultaneously collected over the SpO2 range covered. The Pulse Rate Accuracy Root Mean Square (Arms) performance of the VitalDetect™ pulse oximetry system, were expected to meet a specification of 3 bpm.

Design Details

Primary Purpose: Device Feasibility
Intervention Model: Single Group Assignment
Interventional Model Description: Testing was conducted under normal office environment conditions. The VitalDetect™ pulse oximetry was placed on the right index finger of all subjects to evaluate the SpO2 and pulse rate accuracy performance during steady state non-motion conditions. A Control Pulse Oximetry system was also placed on the subject to evaluate the stability of the draws and the real time oxygen saturation status. The subject was in a reclined position and connected to a breathing circuit, for administering medical grade oxygen and nitrogen. The gas flow delivery was adjusted for subject comfort. Arterial blood samples were drawn during simultaneous data collection from the control pulse oximeter and the test oximeters. The blood was immediately analyzed by Reference CO-Oximetry providing functional SpO2 for the basis of the SpO2 accuracy comparison. The pulse rate for the VitalDetect™ was compared to Reference ECG Heart Rate collected during the study.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluate SpO2 Accuracy Per Standards for Pulse Oximetry. | This study was a comparative, single-center, non-randomized study conducted to evaluate the SpO2 accuracy per standards and guidelines identified above for SpO2 accuracy for pulse oximetry equipment over the range of 70-100% SaO2 under non-motion conditions. Arterial blood sampling measured by functional SaO2 CO-Oximetry, was used as the basis for comparison. As a secondary goal, the pulse rate accuracy was compared to ECG Heart Rate realized over the range throughout the hypoxia procedure. Testing was conducted under normal office environment conditions. | 90 Seconds | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Pulse Rate Accuracy Compared to ECG Heart Rate. | The pulse rate accuracy was compared to ECG Heart Rate as recorded by the S5 Multi-parameter monitor. Passing criteria was an ARMS of 3 bpm or better based measurements observed during the pulse oximetry evaluation. | 90 Seconds |
