| Abstract | A prototype of a new design disposable passenger mask applicable for emergency use in jet transports at altitudes to 40,000 feet was evaluated. Six subjects instrumented to obtain a variety of physiological information were exposed to a chamber flight profile designed around the National Aerospace Standard 1179. The two alternative methods of determining mask performance suggested in this document and based on gas analysis and blood oxygen saturation were used simultaneously in this study. In order to stimulate the respiration to the 30-liters/minute volume levels specified in applicable regulations, the subject exercised on a bicycle ergometer through the chamber flight up to and including 40,000 feet. Air-breathing baselines were established at 10,000 and 14,000 feet with the subject resting. The 14,000-foot baseline determination was repeated at 14,000 feet exercising at the same work load level as used in the high-altitude tests. The mask maintained all subjects in a satisfactory physiological condition at all altitudes up to and including 40,000 feet for the duration of exposure used in these tests. |
