A 67-year-old man suffering cardiopulmonary arrest had an apparently uneventful placement of an esophageal obturator airway (EOA) by a well-trained ambulance crew. Subsequent clinical evaluation showed ventilation to be marginal. Attempts to insert an endotracheal tube were unsuccessful because the larynx could not be visualized. A subsequent postmortem examination showed that the EOA tube was kinked and bent back on itself so that the distal (balloon) end lay underneath the larynx, displacing it anteriorly.
一名67岁的男子发生心肺骤停，训练有素的急救人员为其置入食管阻塞气道（EOA）时过程看似顺利。随后的临床评估显示通气效果不佳。由于无法看到喉部，尝试插入气管内导管未成功。随后的尸检显示，EOA管出现扭结并向后弯折，致使远端（气囊）端位于喉部下方，将喉部向前推移。
