To search for evidence of capacity management in patients undergoing extracorporeal membrane oxygenation support therapy, and summarize the evidence to provide evidence-based basis for medical staff to evaluate and manage the capacity of such patients.

This study was an evidence-based nursing study. Based on the 6S evidence model, relevant evidence on patient volume management in extracorporeal membrane oxygenation support therapy was systematically searched for relevant evidence on patient volume management in extracorporeal membrane oxygenation support therapy from top to bottom, including UpToDate, the National Guidelines Library of the United States, the Scottish Interhospital Guidelines Network, the Medical Guidelines Network, the Extracorporeal Life Support Organization website, Cochrane Library, PubMed, CINAHL, Wanfang, China National Knowledge Infrastructure, and the Chinese Biomedical Literature Database. Based on the inclusion criteria, clinical guidelines, expert consensus, clinical decision-making, evidence summary, and systematic evaluation were selected for literature quality evaluation to extract the best evidence. The search period was from April 10, 2017 to April 10, 2022.

A total of 11 articles were included and 20 pieces of evidence were extracted, which were categorized into four categories: extracorporeal membrane oxygenation team composition and personnel qualifications, evaluation and monitoring, capacity management objectives, and capacity management measures.

Based on a large amount of evidence of extracorporeal membrane oxygenation support for patient capacity management, this study can provide a reference basis for clinical workers to develop extracorporeal membrane oxygenation support treatment capacity management plans.
