Representative traces of a patient (patient 1) during the randomized trials for spontaneous breathing, face mask at PEEP and PS of 5 cmH 2 O, helmet standard at PEEP and PS of 5 cmH 2 O, helmet standard at PEEP and PS of 8 cmH 2 O, helmet next at PEEP and PS of 5 cmH 2 O, helmet next at PEEP and PS of 8 cmH 2 O, and spontaneous breathing. Pao, Flow, Pes, Pga, and Pdi are shown from top to bottom. FM, face mask; HN, helmet next; HS, helmet standard; Pao, pressure at the airway opening; Pdi, transdiaphragmatic pressure; PEEP, positive end-expiratory pressure; Pe, esophageal pressure; Pga, gastric pressure; PS, pressure support.
