What is the compressibility factor for the patient circuit when the ventilator volume is set at 200 mL, the recorded peak inspiratory pressure is 72 cm H2O, and the measured volume is 148 mL?
a. 0.36 cm H2O/mL c. 2.06 mL/cm H2O
b. 0.49 cm H2O/mL d. 2.78 mL/cm H2O
ANS: C
The compressibility factor of a patient circuit is the circuit's tubing compliance. Tubing compli-ance equals the measured volume divided by the measured peak inspiratory pressure (Tubing compliance = Volume/Peak inspiratory pressure). Tubing compliance = 148 mL ÷ 72 cm H2O = 2.06 mL/cm H2O.
