目的:探讨无创正压通气对煤工尘肺稳定期患者的康复作用。方法:采用自身及组间对照法,测定煤工尘肺患者使用BiPAP呼吸机辅助通气3周前后的肺通气功能、动脉血气分析、生存质量评估、6min步行距离、左膈肌最大移动度等变化情况,以评价该治疗对煤工尘肺患者的康复作用。结果:该治疗能减轻患者的呼吸困难,增加运动耐力,但对患者肺通气功能、膈肌移动度及生存质量评估影响不大。结论:无创正压通气治疗对煤工尘肺患者有一定的康复作用。
Objective: To investigate the rehabilitation effect of non-invasive positive pressure ventilation on patients with stable pneumoconiosis during coal workers. Methods: The changes of pulmonary ventilation function, arterial blood gas analysis, quality of life assessment, walking distance of 6 minutes and maximal movement of left diaphragm were measured before and after using BiPAP ventilator-assisted ventilation in coal worker’s pneumoconiosis patients by self and group control method. To evaluate the treatment of coal workers with pneumoconiosis rehabilitation. Results: The treatment can reduce the patient ’s breathing difficulties and increase exercise endurance, but has little effect on pulmonary function, diaphragmatic muscle mobility and quality of life assessment. Conclusion: Noninvasive positive pressure ventilation has a certain rehabilitation effect on coal workers with pneumoconiosis.
