Following current cardiopulmonary resuscitation (CPR) guidelines, which recommend chest compressions at "the center of the chest," ~50% of patients experiencing out-of-hospital cardiac arrest (OHCA) undergo aortic valve (AV) compression, obstructing blood flow. We used resuscitative transesophageal echocardiography (TEE) to elucidate the impact of uncompressed vs. compressed AV on outcomes of adult patients experiencing OHCA.

不压迫主动脉瓣的心肺复苏可增加院外心脏骤停患者恢复自主循环的机会：一项前瞻性观察队列研究。


目前的心肺复苏 (CPR) 指南建议在“胸部中心”进行胸外按压，约 50% 的院外心脏骤停 (OHCA) 患者会受到主动脉瓣 (AV) 压迫，从而阻碍血流。我们使用复苏性经食管超声心动图 (TEE) 来阐明未压缩 AV 与压缩 AV 对经历 OHCA 的成年患者的结果的影响。
