aOrder of application of the two recruitment maneuvers: A for extended Sigh, B for continuous positive airway pressure.

bDiffuse, diffuse loss of aeration; Focal, focal loss of aeration; Patchy, patchy loss of aeration.

cD, deceased; S, survived.

ARDS, acute respiratory distress syndrome; Aspiration, aspiration pneumonia; Delay, delay between the diagnosis of acute respiratory distress syndrome and inclusion in the study; LIP, lower inflection point on the pressure-volume curve; PBW, predicted body weight; rpm, respirations per minute; RR, respiratory rate; SAPS, simplified acute physiologic score (evaluated at the beginning of the study); UIP, upper inflection point on the pressure-volume curve; VT, tidal volume.
