目的 构建心血管疾病危重患者俯卧位通气方案（以下简称“方案”），为在心血管危重患者中安全、有效地实施俯卧位通气提供参考依据。 方法 检索中英文数据库、指南网站和专业网站获取相关文献，选取临床专家进行半结构访谈，结合文献研究和访谈结果形成方案初稿，通过德尔菲专家函询，对条目进行修改和增删，形成方案终稿。 结果 共15名专家完成2轮函询，问卷有效回收率均为100%。 专家权威系数为0.855，经过2轮函询后肯德尔和谐系数为0.236（P<0.001）。 最终形成的方案含25个条目，各条目的重要性赋值为4.27~ 5.00分。 结论 该研究构建的俯卧位通气方案科学可靠，针对性强，可为临床实施提供一定的参考价值。

Objective This study aims to construct a program for prone position ventilation in cardiovascular critical patients，and to provide scientific references for the safe and effective implementation of prone ventilation in these patients. Methods The study group searched domestic and international databases，guideline websites and professional websites to retrieve relevant literature，and then selected clinical experts for semi-structured interviews， the first draft of the program was formed based on the literature analysis and the interviews. Delphi technique method was used to modify，add or delete items，and then the final draft of the program was formed. Results 2 rounds of Delphi consultation were conducted among 15 experts，and the effective recovery rate of the questionnaire was 100%. The expert authority coefficient was 0.855，and the Kendall harmony coefficient after the second round of consultation was 0.236 （P <0.001）. The final draft of the program contained 25 items，the mean value of importance assignment of items was 4.27 ~5.00. Conclusion The program constructed in this study is scientific， specific and reliable，with reference significance for clinical implementation.
