Abstract: Objective To analyze the effect of manual hyperinflation(MHI) on the quality of life of stroke patients undergoing tracheotomy. 
Methods A total of 100 stroke patients undergoing tracheotomy after admission to the Department of Rehabilitation Medicine of Linfen Central Hospital, Shanxi Province were selected and divided into two groups. The control group (n=50) received conventional tracheotomy airway management, and the experimental group (n=50) received MHI on the basis of the control group. The total length of hospital stay before and after the intervention, the length of intensive care unit (ICU) stay, time to extubation, lung function, quality of life, activities of daily living (ADL), motor function, swallowing function classification and the incidence of complications were compared between two groups. 
Results After intervention, forced vital capacity (FVC%) and forced expiratory volume in one second (FEV1%) in both groups were significantly increased, which were higher in the experimental group than in the control group (P＜0.05). The scores of physiology, psychology, independence, social relationship, environment and spirit of the two groups were significantly increased, which were higher in the experimental group than in the control group (P＜0.05). Barthel index (BI) and Fug1-Meyer motorassessment (FMA) score in both groups were significantly increased, which were higher in the experimental group than in the control group (P＜0.05). The classification of swallowing function in the two groups was significantly improved, which were better in the experimental group than in the control group (P＜0.05). The total incidence of complications in experimental group (10.00%) was significantly lower than that in control group (P＜0.05). The total length of hospital stay, length of ICU stay and time to extubation in the experimental group were significantly shorter than those in control group (P＜0.05). 
Conclusion MHI can effectively improve the lung function of stroke patients undergoing tracheotomy, and significantly improve the motor function, swallowing function and the quality of life, reduce the incidence of complications, and promote the early recovery of patients. Therefore, it is worthy of clinical application.
