Abstract

Objective

To develop a comprehensive pulmonary rehabilitation program based on circadian rhythm principles for critically ill patients with severe pneumonia and evaluate its efficacy.

Design

A feasibility study with convenience sampling.

Setting

A grade A tertiary hospital.

Participants

Ninety-three (N=93) patients with severe pneumonia. A total of 47 patients admitted from January to March 2025 were assigned to the control group, and 46 patients admitted from April to June 2025 were allocated to the intervention group.

Interventions

The control group received routine pulmonary rehabilitation; the intervention group was given a circadian rhythm-based comprehensive pulmonary rehabilitation program in addition to routine care.

Main Outcome Measures

Duration of mechanical ventilation, length of hospital stay, pulmonary rehabilitation compliance rate, pulmonary function indicators, sleep quality, and patient satisfaction with nursing care.

Results

Compared with the control group, the intervention group had significantly shorter durations of mechanical ventilation and hospital stay (P<.05). Additionally, the intervention group showed a significantly higher pulmonary rehabilitation compliance rate, better pulmonary function indicators, higher sleep quality scores, and greater patient satisfaction with nursing care than the control group (all P<.05).

Conclusions

The circadian rhythm-based comprehensive pulmonary rehabilitation intervention provides a rehabilitation model that aligns with the biological rhythms of critically ill patients with severe pneumonia. This approach may reduce the duration of mechanical ventilation and hospital stay, improve pulmonary function and sleep quality, and enhance patient satisfaction with nursing care.

基于昼夜节律的肺部康复在重症肺炎患者中的应用——方便抽样的可行性研究

目的为重症肺炎危重患者制定基于昼夜节律原理的综合肺康复方案并评价其疗效。设计可行性研究，方便抽样。设三级甲等医院。参与者：93例重症肺炎患者。将2025年1月至3月收治的47例患者分为对照组，将2025年4月至6月收治的46例患者分为干预组。对照组患者给予常规肺部康复治疗；干预组在常规护理的基础上给予基于昼夜节律的综合肺部康复方案。主要观察指标：机械通气时间、住院时间、肺康复依从率、肺功能指标、睡眠质量、患者护理满意度。结果干预组患者机械通气时间和住院时间较对照组显著缩短（p < 0.05）。干预组肺康复依从率、肺功能指标、睡眠质量评分、患者护理满意度均显著高于对照组（p < 0.05）。结论基于昼夜节律的肺部综合康复干预为重症肺炎危重患者提供了一种符合生物节律的康复模式。该方法可减少机械通气时间和住院时间，改善肺功能和睡眠质量，提高患者对护理的满意度。
