What spontaneous pressure-controlled breath mode allows separate regulation of the inspiratory and expiratory pressures?
 
  a. Bilevel positive airway pressure
  b. Continuous positive airway pressure
  c. Pressure-supported ventilation
  d. Pressure-controlled intermittent mandato-ry ventilation

Question 2

For patients with respiratory insufficiency, pressure-supported ventilation (PSV) has all of the following advantages over spontaneous breathing except:
 
  a. decreased respiratory rate.
  b. increased VT.
  c. decreased O2 consumption.
  d. increased muscle activity.

Answer to Question 1

ANS: A
With BiPAP, inspiratory positive airway pressure (IPAP or pressure-supported ventilation) and expiratory positive airway pressure (EPAP or positive end expiratory pressure) are set.

Answer to Question 2

ANS: D
Clinical studies have shown that compared with spontaneous breathing (including that occurring during synchronized intermittent mandatory ventilation), PSV can result in a decreased respira-tory rate, increased tidal volume, reduced respiratory muscle activity, and decreased oxygen consumption.
