Abstract
The arterial O2 saturation of 14 normal children breathing air, as detd. by a modified Roughton-Scholander technique, ranged from 91.5 to 95.3%, with an avg. value of 93.1%. During the inhalation of 100% O2 the blood of each child became fully saturated and in addition an avg. amt. of 1.09 vol. % was carried in physical soln. The arterial O2 saturation while breathing air is 5.5% lower than the avg. value detd. spectrophotometrically, reported by Drabkin and Schmidt. Likewise the arterial O2 content during the inhalation of 100% O2 is 5.3% lower than would be expected on theoretical grounds. No adequate reason for these disparities has yet been advanced.Keywords
