In what way do BiPAP units differ from CPAP units?
 
  a. BiPAP applies different pressure levels on inspiration and exhalation.
  b. BiPAP units cost significantly more that CPAP units.
  c. BiPAP operates on electricity.
  d. BiPAP simulates spontaneous breathing.

Question 2

How does CPAP improve breathing in the patient with OSA?
 
  a. Stimulation of the phrenic nerve
  b. Pneumatic splinting of the upper airway
  c. Stimulation of upper airway muscles
  d. Repositioning of the epiglottis

Answer to Question 1

ANS: A
Unlike conventional CPAP, BiPAP is titrated by increasing inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP) separately in response to apnea, hypop-nea, and desaturation.

Answer to Question 2

ANS: B
CPAP therapy is believed to work by splinting the upper airway open, thus raising the intralu-minal pressure of the upper airway above a critical transmural pressure of the pharynx and hypo-pharynx that is associated with airway closure.
