Centrifuge Testing of a G Compensated/Pressure Demand Oxygen Regulator.
Abstract
Six subjects were exposed to unassisted positive pressure breathing at levels not exceeding 30 mmHg breathing pressure while riding on a centrifuge. Acceleration in the +Gz direction was applied as either a ramp or a plateau and conditions ranged from relaxed to unassisted positive pressure breathing with an anti-G suit. The purpose of this study was to evaluate the performance of a G compensated positive pressure breathing regulator with respect to stated output pressure versus +Gz level, the pressure control concept/schedule employed, and subject acceleration tolerance. The regulator was found to perform as stated given the pressure range of interest and the experimental conditions. The pressure control concept/schedule and acceleration tolerance were related factors. It was found that the subjects who rode to higher =Gz levels received higher levels of breathing pressure and in turn an increase in acceleration tolerance. Keywords: Oxygen regulators; Breathing pressure; G compensation.
