Methodology of Noninvasive Positive Pressure Ventilation in Acute Respiratory Failure

Abstract

In many patients with acute respiratory failure (ARF), noninvasive positive pressure ventilation (NPPV) via a mask can be equally as effective in improving the pathophysiology of respiratory failure and correcting gas exchange abnormalities as conventional ventilation via an endotracheal tube [1]. When effective, NPPV avoids the complications associated with endotracheal intubation, improves patient comfort and preserves airway defense mechanisms, speech and swallowing. Furthermore, NPPV provides greater flexibility in instituting and removing mechanical ventilation (MV).
