[Weaning of veno-venous extracorporeal membrane oxygenation: when to use the "resting lung"].

Differences in weaning strategies for veno-venous extracorporeal membrane oxygenation (VV-ECMO) are based on expert opinions rather than clinical evidence. Therefore, each center has its own "unique skills". The timing of VV-ECMO weaning has not received due attention. It is difficult to find research on the choice of VV-ECMO weaning timing in the database. There are few studies involving VV-ECMO that describe the weaning process in detail. At present, the weaning process of VV-ECMO is mainly based on expert opinions. This article classified the current VV-ECMO weaning strategies, appealed to a unified VV-ECMO weaning protocol in China as soon as possible, and further improved the prognosis of patients with extracorporeal life support.静脉-静脉体外膜肺氧合（VV-ECMO）的撤机策略主要是基于专家意见，而不是研究证据，所以各中心都有自己的临床标准。VV-ECMO撤离时机的选择并没有得到应有的重视，数据库中很难找到关于VV-ECMO撤离时机选择的研究，涉及VV-ECMO的研究也鲜有详细描述撤离的流程，目前VV-ECMO的撤离流程以专家意见为主。本文对现行的VV-ECMO撤离策略进行分类阐述，呼吁在国内尽快建立统一的VV-ECMO撤离方案，进一步提高体外生命支持患者的预后。.
