Where applicable, results are expressed as mean ± standard deviation. Pao₂/Fio₂ ratio is provided under a positive end-expiratory pressure level of 10 cmH₂O. CAP, community-acquired pneumonia; Crs, Chord compliance of the respiratory system; F, female; Fio₂, fractional inspired oxygen; LIP, lower inflection point; M, male; Pao₂, partial arterial oxygen tension; Pplat, plateau airway pressure; SAPS II, Simplified Acute Physiology Score II; UIP, upper inflection point.
