The therapist desires to mechanically ventilate a patient with a mode that provides an increased I:E ratio, encourages spontaneous breathing, and lowers pressure fluctuations as tidal volume is delivered. Which of the following modes would be appropriate?
 
  A. pressure-regulated volume control ventilation
  B. inverse ratio ventilation
  C. airway pressure release ventilation
  D. synchronized intermittent mandatory ventilation

Question 2

What are the physiologic benefits of maintaining alveolar recruitment? I. Recruited alveoli improve ventilationperfusio n matching. II. Transpulmonary pressure decreases. III. The surfactant monolayer does not require repeated reconstruction during ventilation. IV. Pulmonary compliance decreases.
 
  A. I, II only
  B. I, III only
  C. I, II, III only
  D. II, III, IV only

Answer to Question 1

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: Airway pressure release ventilation (APRV) involves the use of long I:E ratios, less variation from in the delivered VT from breath to breath, and a spontaneously breathing patient. In addition to the recruitment effects cause by the long I:E ratios, the required spontaneously breathing has been shown to better distribute ventilation to dependent lung regions, thereby improving ventilation-perfusion relationships.
D. Incorrect response: See Explanation C.

Answer to Question 2

ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Maintaining alveolar recruitment provides several benefits. They include: (1) recruited alveoli improve ventilationperfusio n matching and gas exchange, (2) recruited alveoli appear to have less risk of injury from shear stress from repeated opening and closing, and (3) recruited alveoli do not have to repeatedly construct the surfactant monolayer, thus improving lung compliance.
C. Incorrect response: See explanation B.
D. Incorrect response: See explanation B.
