The amount of pressure required by a ventilator to maintain tidal volume when there is no gas flow is known as:
 
  a. Pplateau. c. peak expiratory pressure.
  b. peak inspiratory pressure. d. Maximum inspira-tory pressure.

Question 2

Patients with restrictive pulmonary disease demonstrate a decrease in which of the following measurements?
 
  1. Vital capacity
  2. Total lung capacity
  3. Forced expiratory flow from 25 to 75 of the vital capacity (FEF25-75)
  4. Ratio of forced expiratory volume in 1 second to vital capacity (FEV1/VC)
  a. 1 and 2 c. 1 and 4
  b. 2 and 3 d. 3 and 4

Answer to Question 1

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.

Answer to Question 2

ANS: A
Patients with restrictive pulmonary disease can have decreases in vital capacity and total lung capacity.
