a. Pplateau. c. peak expiratory pressure.
b. peak inspiratory pressure. d. Maximum inspira-tory pressure.
ANS: A
Pplateau represents the amount of pressure needed to maintain the tidal volume within the patient's lungs during static conditions and is the total pressure required to overcome only elastic forces.
