Effect of Different Inert Gases and Low Pressure Normoxic Environments on Oxygen Uptake in Mice

摘要

Exposure of adult male Swiss albino mice to air at 28C., ground level pressure, for 24 hours resulted in an oxygen uptake of 78.0 ml./hr. (STPD) as compared with 77.4 ml./hr. in 100% oxygen, 77.7 ml./hr. in 80% Ar:20% O2, and 84.2 ml./hr. in 80% He:20% O2. The increase in oxygen consumption in He:O2 at this temperature approached significance (P
