A comparison of vessel sensitivity and vessel constant in oxygen uptake determination with pure oxygen and air as gaseous media.

ABSTRACT

Air proved to be a superior gaseous medium to pure oxygen used for oxygen uptake study in the Warburg apparatus Recording of volume change (vessel sensitivity method) was the only correct method of recording the oxygen uptake. It is concluded that the volume change method should be followed for recording oxygen uptake by Warburg apparatus and pure oxygen should not be used as a gaseous medium.
