Term Description

A ratio with numerator = arterial oxygen partial pressure (PaO2) in mmHg and denominator = fraction of inspired oxygen (FIO2) with no units. If the patient is breathing room air (20% O2) the fraction would be 0.20. It is reported in mmHg. It is a well established marker for lung function during mechanical ventilation and used in many acuity scores like SAPS II, SAPS III, and SOFA.
