Question

Quizplus · Accepted Answer

Noninvasive positive-pressure ventilation (NPPV) is effective in treating patients with hypercarbic (elevated CO2) respiratory failure, including those with nocturnal hypoventilation. It does not improve oxygenation in hypoxic patients and may even worsen acidosis in patients with severe respiratory failure. NPPV is not indicated in hypocarbic patients because it may increase CO2 retention.
