Physiological Effects of Different Oxygen Flow Rates and Ambient Temperatures on Pressure-Suited Subjects Performing Work at Altitude

Abstract

In a series of tests conducted at different ambient temperatures, the physiological effects of various levels of flow rate of ventilating O2 were investigated. Pressure-suited subjects underwent moderate work stress on a bicycle ergometer in an altitude chamber maintained at 5 PSIA. The temperature and relative humidity of the ventilating O2 were maintained constant at 55 deg F and 90-95%, respectively; the duration of the runs was fixed at 2 hours. Within the limits of the ambient temperatures and ventilating flow rates employed in this study, only slight advantages were gained by increasing flow rate, as observed in terms of the physiological measurements made in this study.
