心搏骤停(cardiac arrest,CA)是指心脏机械功能(搏血功能)突然停止,并伴自主呼吸消失和意识丧失的临床急症。针对CA的救治措施称为心肺脑复苏(cardio-pulmonary-cerebral resuscitation,CPCR)。如果抢救不及时,最终导致猝死(sudden death)。在抢救CA过程中,患者自主循环恢复(return of spontaneous circulation,ROSC)只是初级目标,CPCR的终极目标是良好的器官功能,尤其是良好的神经系统功能结局。 Cardiac arrest (CA) refers to a clinical emergency in which the cardiac mechanical function (stroke function) suddenly stops with spontaneous respiration and loss of consciousness. The treatment for CA is called cardio-pulmonary-cerebral resuscitation (CPCR). If the rescue is not timely, eventually leading to sudden death (sudden death). In the salvage of CA, the patient’s return to spontaneous circulation (ROSC) is only the primary goal, and the ultimate goal of the CPCR is good organ function, especially good neurological outcome.
