本例急性心肌梗死患者出现了呼吸心跳骤停，常规心肺复苏无效而行体外心肺复苏。在体外膜氧合辅助期间，该例患者发生血液感染导致的脓毒性休克。在超声等技术的辅助下，通过评估心功能及容量状态，为合理的临床决策提供了依据，并在休克复苏和抗感染等治疗后，患者病情好转。

We report an acute myocardial infarction patient with respiratory cardiac arrest in whom conventional cardiopulmonary resuscitation was invalid and extracorporeal cardiopulmonary resuscitation (ECMO) was performed. During ECMO, bloodstream infections caused septic shock. With the assistance of ultrasound and other techniques, cardiac function and volume status were evaluated, which provided a basis for making rational clinical decision. After shock resuscitation and anti-infection treatment, the patient's condition improved.
