Which of the following statements are features of APRV? I. Cardiac output increases during the inflation phase. II. Spontaneous breathing is possible during the inflation phase. III. Alveolar recruitment occurs during the inflation phase. IV. The long inflation time often causes intrinsic PEEP
A. II, IV only
B. I, II, III only
C. I, III, IV only
D. II, III, IV only
ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response: APRV is a pressure-targeted mode of ventilation. APRV allows for spontaneous breathing to occur during the inflation phase. This capability allows for the use of long inflation times to recruit alveoli while enabling patients to continue to breathe spontaneously. Taken together, the long inflation times (often resulting in intrinsic PEEP) can be considered an alternative way to raise mean pressures and maintain recruitment without applying additional PEEP or Vt.?
