The esophageal obturator airway (EOA) has been considered a beneficial ventilatory technique for use in cardiopulmonary resuscitation (CPR). At present, seven studies in the literature compare the EOA with other means of ventilation in humans; only one is an actual field study of its effectiveness. We reviewed the available literature dealing with the device to define clearly its role in the ventilatory treatment of patients who require CPR. There appears to be no current evidence of the EOA's effectiveness for ventilation in prehospital cardiac arrest, and fatal complications have been reported with its use. The use of the EOA to replace endotracheal intubation in airway management is not substantiated in the literature.
食管阻塞气道（EOA）被认为是一种用于心肺复苏（CPR）的有益通气技术。目前，文献中有七项研究比较了EOA与其他通气方式在人体中的应用；只有一项是关于其有效性的实际现场研究。我们回顾了有关该设备的现有文献，以明确其在需要心肺复苏的患者通气治疗中的作用。目前似乎没有证据表明EOA在院外心脏骤停通气方面有效，并且已有使用该设备导致致命并发症的报道。文献中没有证实使用EOA替代气管插管进行气道管理的合理性。
