  a. Inspiratory pause c. Pressure-control ventilation
  b. End-expiratory pause d. Pressure-release ventilation

Question 2

What is the static lung compliance when the returned tidal volume is 460 mL, the positive end-expiratory pressure is 8 cm H2O, the peak inspiratory pressure is 27 cm H2O, and the plateau pressure is 18 cm H2O?
 
  a. 20 mL/cm H2O c. 46 mL/cm H2O

Answer to Question 1

ANS: B
End-expiratory pause, or expiratory hold, is a procedure performed to estimate the pressure in the patient's lung and ventilator circuit caused by trapped air.

Answer to Question 2

ANS: B
Static lung compliance = Volume  (Plateau pressure  Positive end-expiratory pressure) = 460 mL  (18 cm H2O  8 cm H2O) = 460 mL  10 cm H2O = 46 mL/cm H2O.
