What is the static lung compliance when the returned tidal volume is 700 mL, the positive end-expiratory pressure is 10 cm H2O, the peak inspiratory pressure is 45 cm H2O, and the plat-eau pressure is 35 cm H2O?
a. 0.160 L/cm H2O c. 0.028 L/cm H2O
b. 0.020 L/cm H2O d. 0.735 L/cm H2O
ANS: B
Static lung compliance = Volume ÷ (Plateau pressure – Positive end-expiratory pressure) = 0.7 L ÷ (45 cm H2O – 10 cm H2O) = 0.7 L ÷ 35 cm H2O = 0.02 L/cm H2O.
