Trial Outcomes & Findings for Vital USA SpO2 Accuracy Comparison to Arterial Blood CO-Oximetry (NCT NCT04285411)

NCT ID: NCT04285411

Last Updated: 2020-06-02

Results Overview

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.

Participant Flow

Following Institutional Review Board (IRB) approval Title: "Vital USA SpO2 Accuracy Comparison to Arterial Blood CO-Oximetry", Clinimark Study ID# PR 2019-353, eleven healthy adult volunteer subjects were screened and enrolled into the study. One subject was withdrawn due to poor device placement and time sync with the control oximeter.

ARMS SpO2 70-100%
Comparison to Reference CO-Oximetry Accuracy of the VitalDetect™ pulse oximetry system: 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.

SECONDARY outcome

Timeframe: 90 Seconds

Population: Five (5) males, five (5) females (age: 19-38yrs, weight: 105-228 lbs, height: 63-75", BMI: 18.0-34.7). Race / ethnicity, two (2) Black / African-Americans, one (1) Asian, seven (7) White. Nine (9) Non-Hispanic / Non-Latino, one (1) Hispanic /Latino. Skin pigmentation / tones met requirement of at least 2 darkly pigmented or 15 % of the subject pool

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.
