A patient has recently been diagnosed with obstructive sleep apnea. The most appropriate treat-ment includes which of the following?

a. Pressure support ventilation (PSV)
b. Noninvasive positive pressure ventilation (NIV)
c. Continuous positive airway pressure (CPAP)
d. Pressure-controlled continuous mandatory ventilation (PC-CMV)

ANS: C
Continuous positive airway pressure (CPAP) is an accepted method used to treat obstructive sleep apnea. Noninvasive positive pressure ventilation (NIV) would be appropriate if the patient had central sleep apnea, since there would be no respiratory efforts during the apnea periods. Pressure support ventilation (PSV) and pressure- controlled continuous mandatory ventilation (PC-CMV) would require the patient to be intubated.
