Abstract：Objective: To study the therapeutic effect of respiratory muscle training on sleep apnea symptoms, sleep quality and lung function in patients with obstructive sleep apnea syndrome (OSAS). Methods:Forty OSAS patients treated in the Second Affiliated Hospital of Wenzhou Medical University from January 2019 to December 2020 were randomly divided into two groups. The control group was given routine treatment such as weight control and exercise, while the observation group was given guided respiratory muscle training on this basis. The data of body mass index (BMI), pulmonary ventilation function, Epworth Sleepiness Scale (ESS),Pittsburgh sleep quality index (PSQI), respiratory disorder index (AHI) and lowest oxygen saturation (LSaO2) of the patients in two groups were collected and analyzed. Results: There was no significant difference in general condition, pulmonary function and sleep quality between the two groups before treatment (P>0.05). After 6 weeks of treatment, compared with the control group, the observation group had significantly lower AHI, PSQI score and ESS score and the increased LSaO2 than before, with statistical difference (P<0.05). After 6 weeks,the tidal volume (VT), inspiratory capacity (IC), vital capacity (VC), maximum ventilation volume (MVV),maximum mid expiratory volume (MMEF), maximum inspiratory pressure (MIP), the maximum expiratory pressure (MEP) of the observation group were significantly higher than those in the control group (P<0.05). The improvement value of AHI before and after 6 weeks was correlated with that of MIP, MMEF, MEP, MVV and IC,showing statistical significance (P<0.05). Conclusion: Respiratory muscle rehabilitation training combined with general routine treatment can effectively improve daytime symptoms and pulmonary function of OSAS patients.
