Venoarterial extracorporeal membrane oxygenation (VA ECMO) provides mechanical support to the patient with cardiac or cardiopulmonary failure. This paper reviews the physiology of VA ECMO including the determinants of ECMO flow and gas exchange. The efficacy of this therapy may be determined by assessing patient hemodynamics and device flow, overall gas exchange support, markers of adequate oxygen delivery, and pulsatility of the arterial blood pressure waveform.
静脉-动脉体外膜肺氧合(VA ECMO)为心力衰竭或心肺衰竭患者提供机械支持。本文综述了VA ECMO的生理学,包括ECMO流量和气体交换的决定因素。该治疗的疗效可通过评估患者的血流动力学和设备流量、整体气体交换支持、充足氧输送的标志物以及动脉血压波形的搏动性来确定。
