Treatment of acute pulmonary failure by CPAP via face mask: when can intubation be avoided?
Continuous positive airway pressure (CPAP) is used frequently to improve gas exchange in acute pulmonary failure. We investigated clinical and respiratory variables in 98 patients presenting with two or more of the classical criteria for endotracheal intubation and mechanical ventilation. ⋯ Posttraumatic and postoperative pulmonary problems responded better to this therapy than lung dysfunction secondary to left heart failure, sepsis or pneumonia. Abundant expectorations, discoordination of respiratory movements and an increase in arterial carbon dioxide were frequently associated with failure of CPAP by mask and the necessity of endotracheal intubation and mechanical ventilation.
