NITROGEN CLEARANCE FROM THE BLOOD AND SALIVA BY OXYGEN BREATHING

Abstract

By means of a microgasometric method the N clearance from blood and saliva of resting human subjects was detd. during a period of O2 breathing. Eighty-90% of the N was cleared from both the finger blood and the saliva during the first 10 mins., and one-half the remainder was cleared in the following 50 mins. No significant differences were shown between the rate of clearance from the saliva and that from the finger blood. The rate of saturation in air was practically as rapid as the rate of desaturation during O2 breathing.
