"WebBackground: Clinicians and researchers use the P/F-ratio, the ratio between PaO2 and the fraction of inspired oxygen (FiO2), to assess lung injury severity. Ideally, the P/F-ratio should depend solely on a patient's pulmonary condition. Preclinical studies, however, suggest that FiO2 might influence the P/F-ratio by affecting ventilation/perfusion (V/Q) … " - Fio2 and po2 ratio
