Definition of abbreviations: No. = number; NR = nonregistered (e.g., during transport of the patient, or during surgery); O2 mask = hours ventilated via oxygen mask; PC = pressure control; PEEP = positive end-expiratory pressure; PS = pressure support; Total MV = sum of hours on mechanical ventilation from moment of intubation until biopsy (see Table E2 for details).
Data are totals or mean ± SD. Ventilatory settings are averaged from moment of intubation until biopsy.
