Quizplus · Accepted Answer

Indications for NPPV use in patients with COPD and nocturnal hypoventilation include PaCO2 greater than 55 mm Hg or between 50 and 54 mm Hg with nocturnal desaturation, as well as two or more hospitalizations related to hypercapnic respiratory failure. A PaCO2 greater than 65 mm Hg is also an indication. Therefore, choices I, II, and IV are correct.
