目的 了解ICU医务人员对俯卧位机械通气患者气道管理质量评价的认知，为构建俯卧位机械通气患者气道管理质量评价指标体系提供参考依据。方法 采用目的抽样法，于2023年2月—6月对广东省某三级甲等医院的16名ICU医务人员进行半结构式访谈，采用现象学研究Colaizzi 7步法对访谈结果进行分析和主题提炼。结果 提炼出与俯卧位机械通气患者气道管理质量评价相关的3个主题和9个亚主题。结构质量评价相关主题（充足的资源支持、优良的专业素质、科学有效的操作规范与质量标准）、过程质量评价相关主题（落实动态护理评估、规范执行护理操作、及时有效处理相关风险、团队成员配合良好）与结果质量评价相关主题（多维连续监测相关数据、密切关注患者安全）。结论 基于医务人员视角提取的俯卧位机械通气患者气道管理质量评价相关主题可为进一步构建相关护理质量评价指标体系提供参考。

Objective To understand how ICU medical staff cognize the nursing quality evaluation of airway management in prone position mechanically ventilated patients so as to provide reference for construction of a nursing quality evaluation index system for airway management in prone position mechanically ventilated patients. Methods The purposive sampling method was used to conduct semi-structured interviews with 16 ICU medical staff from a tertiary class A hospital in Guangdong Province from February to June 2023.The interview data were analyzed and retracted according to the Colaizzi 7-step analysis of phenomenological data. Results Three themes and nine sub-themes related to airway management quality evaluation in prone position mechanically ventilated patients were extracted. Themes related to structural quality evaluation included sufficient resource support，excellent professional quality，scientific and effective operation specifications and quality standards. Themes related to process quality evaluation included implementation of dynamic nursing assessment，standardized implementation of nursing operations，timely and effective treatment of related risks，good cooperation of team members.，And themes related to outcome quality evaluation included multi-dimensional continuous monitoring of relevant data，close attention to patient safety. Conclusion The themes for airway management quality in prone position mechanically ventilated patients from the perspective of medical staff can provide reference for further construction of a nursing quality evaluation index system.
