严重的心原性肺水肿常导致呼吸衰竭,许多患者需要气管内插管和机械辅助呼吸。本文评价经面罩连续正压给氧对这类患者的效果以及是否可减少气管内插管和机械辅助呼吸的需要。连续39例严重心原性肺水肿所致呼吸衰竭的患者入选,随机经面罩给予吸氧(吸氧组)或者吸氧加连续正压通气(CPAP组),定期测量有关生理指标24小时以上,观察直至出院。治疗后30分钟,CPAP组的呼吸频率由 Severe cardiogenic pulmonary edema often leads to respiratory failure, and many require endotracheal intubation and mechanical assisted breathing. This article assesses the effect of continuous positive pressure oxygen delivery through the mask on these patients and whether or not they reduce the need for endotracheal intubation and mechanical assisted breathing. A total of 39 consecutive patients with respiratory failure due to severe cardiogenic pulmonary edema were enrolled and randomized to receive oxygen inhalation (oxygen inhalation) or oxygen inhalation plus continuous positive airway pressure (CPAP) through a mask at random. Physiological indicators were measured regularly for 24 hours or more, Observation until discharge. Thirty minutes after treatment, respiratory rate of CPAP group was
