Continuous positive airway pressure (CPAP) by face mask

Abstract
The authors studied the use of CPAP by face mask in 44 patients with mild to moderate acute respiratory insufficiency (mean PaO2/FIO2 = 171 +/- 42 (SD). All patients improved their oxygenation (mean PaO2/FIO2 = 300 +/- 68 (SD) after the application of CPAP (mean 9 +/- 3 (SD) cm H2O). One patient developed a respiratory acidemia and was intubated. No other significant complications or adverse side effects occurred. The authors conclude that CPAP by face mask in a select group of patients will improve lung function and arterial oxygenation without the use of tracheal intubation and mechanical ventilation.
