Clinical Trial Summary

This study aims to investigate dose based oxygen delivery vs. continuous flow of oxygen during simulated altitude conditions as would be experienced after a loss of pressure during commercial aircraft flight. Testing will be performed at rest and during light exercise at a simulated altitude of 15,000 feet in a hypobaric chamber. Performance of the two oxygen delivery systems will be compared using oxygen saturation determined by pulse oximetry.

Outcome

Type Measure Description Time frame Safety issue
Primary Device performance, as measured by SpO2 The same subject must complete both oxygen delivery system exposures for the data to be used in system performance analysis. Equivalence of the two oxygen delivery systems will be defined as the lack of statistically significant difference (N=20) in SpO2 during the last minute of exercise between the pulse and continuous flow oxygen delivery systems. Average minimum SpO2 over the last minute of the test period will be reported. one minute
