Worsening lung compliance during pressure-controlled ventilation would cause which of the fol-lowing?
a. A decrease in peak pressure c. A decrease in vol-ume delivery
b. An increase in peak pressure d. An increase in peak flow rate
ANS: C
During pressure-controlled ventilation, the delivery of the volume varies according to the charac-teristics of the lungs. Worsening lung compliance is indicative of stiffening lungs. This would cause less volume to be delivered with the same set pressure.
