Cardiac arrest is a common condition with low survival rates. Point-of-care ultrasound (POCUS) has been increasingly integrated in cardiac arrest care to enhance diagnostic accuracy and guide interventions. POCUS can be divided into cardiac and non-cardiac applications. Cardiac applications include assessment of cardiac tamponade, pulmonary embolism, ventricular fibrillation, and chest compression quality. Non-cardiac applications include endotracheal tube confirmation, pneumothorax assessment, and evaluation of aortic and intra-abdominal pathology. POCUS can also be used to identify the presence or absence of a pulse more rapidly and accurately than manual palpation. Prognostic utility is highest in traumatic arrests, but more limited in non-traumatic arrests. In appropriately trained individuals, POCUS is a valuable component of cardiac arrest care.
心脏骤停是一种常见病症，生存率较低。床旁超声（POCUS）已越来越多地融入心脏骤停的救治过程中，以提高诊断准确性并指导干预措施。POCUS可分为心脏和非心脏应用。心脏应用包括评估心包填塞、肺栓塞、心室颤动和胸外按压质量。非心脏应用包括确认气管插管、评估气胸以及评估主动脉和腹部内病变。与手动触诊相比，POCUS还可用于更快速、准确地确定是否存在脉搏。其在创伤性心脏骤停中的预后价值最高，但在非创伤性心脏骤停中的价值较为有限。对于经过适当培训的人员，POCUS是心脏骤停救治的重要组成部分。
