目的 探讨左心室辅助装置植入患者首次离床活动的真实感知与体验，为左心室辅助装置植入患者早期康复运动的干预提供依据。 方法 本研究为描述性质性研究，采用目的抽样法，选取2024年6月—2025年3月南京市某三级甲等医院左心室辅助装置植入患者18例进行半结构式深度访谈。采用内容分析法整理访谈资料。 结果 共提炼4个主题，8个亚主题：生理适应体验（躯体不适感、运动功能失调），设备适应挑战（设备束缚感、报警焦虑），心理适应历程（死亡恐惧、希望体验），支持系统需求（医护指导需求、器械辅助需求）。结论 左心室辅助装置植入患者首次离床活动存在诸多困难与复杂的情感体验，医护人员应主动关注患者心理变化，提供鼓励及健康宣教，制订患者离床活动的标准化流程，确保患者活动期间安全，促进左心室辅助装置植入患者术后早期康复。

Objective To explore the real perception and experience of patients with implanted left ventricular assist device during their first ambulation out of bed，and to provide evidence for interventions in early postoperative rehabilitation exercise for those patients with implanted left ventricular assist device. Methods A descriptive qualitative study was adopted. Through purposive sampling，18 patients with implanted left ventricular assist device at a tertiary Grade A hospital in Nanjing from June 2024 to March 2025 were selected for semi-structured in-depth interviews. Content analysis was applied to organize and analyze the interview data. Results Four themes with eight sub-themes were extracted：physiological adaptation experience（physical discomfort，motor dysfunction），device adaptation challenges（sense of device constraint，alarm-related anxiety），psychological adaptation process（fear of death，experience of hope），and support system needs（need for medical staff guidance，need for assistive devices）. Conclusion Patients with implanted left ventricular assist device encounter multiple difficulties and complex emotional experiences during their first ambulation out of bed. Medical staff should actively monitor patients’ psychological changes，offer encouragement and health education，develop standardized procedures for patients’ ambulation out of bed，ensure patients’ safety during activities，and facilitate the early postoperative rehabilitation of patients with implanted left ventricular assist device.
