简要总结

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.

研究组 & 干预措施

Pneumatic Pulsed Flow

结局指标

主要结局

Device performance, as measured by SpO2

时间窗: one minute

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.
