心肺脑复苏(CPCR)是急诊医学的重要课题之一。及时畅通呼吸道,进行有效的人工呼吸是CPCR成功的关键。一直以来,气管内插管被认为是建立人工气道的最佳方案,但插管操作须经专业人员进行,往往在等待过程中错失抢救时机。2006年以来,我们采用新型(第2代)喉罩(LMA)建立有效人工气道 Cardiopulmonary resuscitation (CPCR) is one of the important topics in emergency medicine. Timely open the respiratory tract, effective artificial respiration is the key to CPCR success. Traditionally, endotracheal intubation is considered the best option for establishing an artificial airway, but intubation procedures must be performed by a professional and tend to miss the timing of the rescue while waiting. Since 2006, we have adopted a new (2nd generation) laryngeal mask (LMA) to establish an effective artificial airway
