The esophageal obturator airway (EOA) has been in use for over a decade and has been inserted over 3 million times. It has given rise to a body of literature, some of it controversial, concerning the role of the device. Data concerning the ventilatory efficiency, safety, complications, limitations, indications, and contraindications as well as mortality and morbidity associated with its use are presented and its present role in CPR is described. In line with the recommendations of the 1985 Standards Committee, the EOA is regarded as a useful device in CPR, which complements the endotracheal tube in the training of paramedics.
食管阻塞气道（EOA）已使用了十多年，插入次数超过300万次。关于该装置的作用，已产生了大量文献，其中一些存在争议。本文介绍了有关其通气效率、安全性、并发症、局限性、适应证和禁忌证的数据，以及与使用该装置相关的死亡率和发病率，并描述了其目前在心肺复苏中的作用。根据1985年标准委员会的建议，EOA被视为心肺复苏中的一种有用装置，它在护理人员培训中是气管内插管的补充。
