Vital USA SpO2 Accuracy Comparison to Arterial Blood CO-Oximetry

Results of the SpO2 and Pulse Rate Accuracy Comparison of VitalDetect™ to Arterial Blood CO-Oximetry and Reference ECG

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

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.

Inclusion Criteria

1. 10-15 Adults with a minimum of 3 males and a minimum of 3 females, with the balance made up of either
2. Subject must have the ability to understand and provide written informed consent
3. Subject is 18 to 50 years of age

Exclusion Criteria

1. Subject is considered as being morbidly obese (defined as BMI >39.5).

2. Compromised circulation, injury, or physical malformation of fingers, wrist, hands, ears or forehead/skull or other sensor sites which would limit the ability to test sites needed for the study.
