Fig. 2. Volume waveform: C = 0:1 L/cmH 2 O, R i = R e = 20 cmH 2 O/L/s,
P set = 22 cmH 2 O, P peep = 5 cmH 2 O, P sen = 15 cmH 2 O, t tot = 6 s, f = 20
breaths/min., 20 consecutive breaths, = 0:35. The solid curves correspond to
the inspiration volume and the dotted curves correspond to the expiration volume.
