Calculate dynamic compliance given the following clinical data: tidal volume 600 mL, peak in-spiratory pressure (PIP) 28 cm H2O, plateau pressure (Pplateau) 15 cm H2O, positive end-expiratory pressure (PEEP) 10 cm H2O, and CT 2 mL/cm H2O
a. 30.2 mL/cm H2O
b. 31.3 mL/cm H2O
c. 38 mL/cm H2O
d. 44.1 mL/cm H2O
ANS: B
Dynamic compliance = tidal volume (VT) − [(PIP − PEEP) ? CT]/(PIP − PEEP) = 600 − [(28 − 10) ? 2]/(28 − 10) = (600 − 36)/18 = 31.3 mL/cm H2O.
