Abstract：Objective To explore the effects of active circulatory breathing technique combined with humidified high-flow oxygen therapy on respiratory muscle function and pulmonary aspiration in stroke patients undergoing tracheotomy.Methods A total of 70 stroke patients receiving tracheotomy in Cangzhou People's Hospital from May 2022 to May 2023 were recruited and divided into observation group and control group by random number table method,with 35 cases in each group.The control group received humidified high-flow oxygen therapy,while the observation group received active circulatory breathing technique combined with humidified high-flow oxygen therapy.The sputum viscosity,respiratory muscle function,lung function,Penetration-Aspiration Scale(PAS)scores and Functional Independence Measurement(FIM)scores were compared between the two groups.Results After the treatment of 2 weeks,the sputum viscosity was sig-nificantly improved compared with that before treatment in both groups(P＜0.05),and the proportion of the patients with sputum viscosity of Ⅰ-Ⅱ degrees in the observation group was higher than that in the control group,and the differences were statistically significant(P＜0.05).After treatment,the levels of maximum inspiratory pressure(MIP),maximum expiratory pressure(MEP),forced expiratory volume in 1 second(FEV1),forced vital capacity(FVC)and FEV1/FVC in both groups were significantly increased compared with those before treatment(P＜0.05),and the levels of MIP,MEP,FEV1,FVC and FEV1/FVC in the observation group were higher than those in the control group,and the differ-ences were statistically significant(P＜0.05).Compared with those in both groups before treatment,the PAS scores and the incidence of pulmonary aspiration in both groups after treatment were significantly decreased(P＜0.05),and the FIM scores in both groups after treatment were significantly increased(P＜0.05).After treatment,the PAS scores and the incidence of pulmonary aspiration in the observation group were lower than those in the control group,and the FIM scores in the observation group were higher than those in the control group,and the differences were statistically significant(P＜0.05).During the treatment period,no adverse events related to the treatment measures were observed in both groups.Conclusion Active circulatory breathing technique combined with humidified high-flow oxygen therapy can improve respiratory muscle function and lung function,reduce sputum viscosity and the incidence of pulmonary aspiration,and improve the patients'quality of life.
