Based upon the following patient information, calculate the patient's static lung compliance: ex-haled tidal volume (VT) is 675 mL, peak inspiratory pressure (PIP) is 28 cm H2O, plateau pressure (Pplateau) is 8 cm H2O, and PEEP is set at 5 cm H2O
a. 0.02 L/cm H2O
b. 0.03 L/cm H2O
c. 0.22 L/cm H2O
d. 0.34 L/cm H2O
ANS: C
The formula for calculating effective static compliance is Cs = VT/(Pplateau − EEP).
