Oxygen is among the most frequently administered medical therapies, with a level that is commonly adjusted according to the reading on a pulse oximeter that measures patients’ oxygen saturation.

ARTERIAL oxygenation during apnea may now be studied with greater accuracy. The recent development of the polarograph 1–3 has made it possible to obtain direct arterial-oxygen-tension determinations ...
