Arterial/alveolar oxygen tension ratio: a critical appraisal.
A critical analysis of the arterial/alveolar oxygen tension ratio (a/APO2) is presented by rearranging the terms of the pulmonary shunt equation. The influence of the shunt and inspired oxygen concentration on a/APO2 are illustrated. It is shown that, despite reports to the contrary, a/APO2 varies with F1O2, particularly at high shunt levels.
