What is the transairway pressure from the information found in the figure?
 
  a. 10 cm H2O c. 25 cm H2O
  b. 15 cm H2O d. 35 cm H2O

Question 2

Increasing the functional residual capacity of a spontaneously breathing patient to improve oxy-genation can be accomplished by which of the following?
 
  a. Inspiratory plateau c. Negative end-expiratory pressure
  b. Positive end-expiratory pressure d. Continuous positive airway pressure

Answer to Question 1

ANS: B
Transairway pressure = Peak inspiratory pressure  Plateau pressure = 35 cm H2O  20 cm H2O = 15 cm H2O.

Answer to Question 2

ANS: D
Continuous positive airway pressure is a technique in which a patient breathes spontaneously at an elevated baseline pressure. This increases the functional residual capacity and mean airway pressure and improves lung recruitment and oxygenation.
