THE GAS EXCHANGE OF ANIMALS EXPOSED TO 100% OXYGEN AT ATMOSPHERIC PRESSURE.
Abstract
Rats were exposed to 100% oxygen at near atmospheric pressure for times long enough to cause death or for 100 hours. The gas exchange was estimated from summations of carbon dioxide removed from the environmental system and oxygen added to it and from these the gas exchange ratio was computed. The normal lowering during fasting could be observed. Two periods of lowered exchange ratio occurred during the oxygen exposures, one immediately following change-over from air to oxygen, and another that occurred after about 40 hours on oxygen. It appears that the first may be associated with the transport and elimination of CO2. The second appears to be associated with the anorexia and fasting characteristics of oxygen toxicity. (Author)
