The relationship between the arterial-alveolar oxygen partial pressure ratio (PaO2/PAO2) and different fractions of inspired oxygen (FIO2) was studied using a bicompartmental computer model. PaO2/PAO2 was found to be less stable than in previous clinical works probably because the venous admixture varied with changes in the FIO2.
