Palanidurai, S., Phua, J., Chan, Y.H. et al. P/FP ratio: incorporation of PEEP into the PaO2/FiO2 ratio for prognostication and classification of acute respiratory distress syndrome. Ann. Intensive Care 11, 124 (2021).

The current Berlin definition of acute respiratory distress syndrome (ARDS) uses the PaO2/FiO2 (P/F) ratio to classify severity. However, for the same P/F ratio, a patient on a higher positive end-expiratory pressure (PEEP) may have more severe lung injury than one on a lower PEEP.

"... the multifactorial P/FP ratio has a greater predictive validity for mortality in ARDS for patients on a PEEP of > 5 cmH2O than the P/F ratio. Its prognostic ability progressively increases with higher levels of PEEP. Changes in severity classification when the P/FP ratio is used instead of the P/F ratio reflect both true illness severity and the applied PEEP strategy."
