Table 2. Spirometry Data

These data are for all patients and all times. Data are presented as mean ± SD and range.

* Not measured with spontaneous ventilation.

MV = minute volume; V1.0%= the ratio of passively exhaled volume during the first second to the total expiratory tidal volume; PEEP = positive end-expiratory pressure; Ppeak = maximum airway pressure; Pplat = end-expiratory pressure after inspiratory pause.
