Often the clinician must act to ensure adequate oxygenation and ventilation before a definitive diagnosis is achieved. The treatment of acute respiratory distress requires an aggressive approach that entails use of medications, oxygen, and often positive pressure ventilation. Historically, patients who required positive pressure ventilation underwent endotracheal intubation (ETI) and were placed on a mechanical ventilator. However, over the past decade there has been an increased use of noninvasive positive pressure ventilation (NIV).1,2 As opposed to ETI, NIV uses an external mask interface to deliver positive pressure to the patient.
