Noninvasive positive pressure ventilation: what is its role in treating acute respiratory failure?

Noninvasive positive pressure ventilation (NIPPV) is a viable option in treating appropriately selected patients with acute respiratory failure. It is often well tolerated, and it avoids endotracheal intubation with its potential complications. Moreover, gas exchange is reportedly improved. Several issues relating to the use of NIPPV are unresolved, however. The optimal interface, best ventilator mode, and patient selection criteria have not been firmly established. Also, studies are needed to compare the efficacy, safety, and cost-effectiveness of NIPPV and standard endotracheal ventilation. Despite these unresolved issues, NIPPV clearly represents an important addition to the techniques available in managing acute respiratory failure. Except in situations in which immediate endotracheal intubation is required, it may become first-line therapy in elderly patients in whom resuscitation status is unsettled.
