A 76-year-old woman was found in cardiopulmonary arrest with her head submerged in water in a bathtub. Despite cardiopulmonary resuscitation (CPR) for over 1 h by professional emergency technicians and medical doctors, the patient died. Postmortem computed tomography revealed not only pulmonary edema associated with drowning but also the presence of intravascular gas in the pulmonary artery, liver, kidneys, heart (right ventricle), and brain. It was speculated that intravascular gas was generated and spread to multiple organs during CPR procedures via the alimentary tract and lungs, which had been damaged by ischemia after cardiopulmonary arrest. Prolonged CPR procedures may involve the risk of additional organ damage and systemic air emboli.
一位 76 岁女性被发现在浴缸中头浸在水中处于心肺停止状态。尽管专业急救技术员和医生进行了超过 1 小时的心肺复苏（CPR），但患者还是死亡了。尸检计算机断层扫描不仅显示了与溺水相关的肺水肿，还显示了肺动脉、肝脏、肾脏、心脏（右心室）和大脑中的血管内气体。据推测，血管内气体是在 CPR 过程中通过胃肠道和肺部产生并扩散到多个器官的，这些组织在心肺停止后因缺血而受损。长时间的 CPR 程序可能会涉及到额外的器官损伤和全身空气栓塞的风险。
