ABSTRACT
Objective To investigate the effect of respiratory training on sleep breathing parameters in cerebral infarction patients complicated with obstructive sleep apnea syndrome(OSAS). Methods From March 1st,2016 to August 30th,2017,60 young and middle-aged patients with cerebral infarction in bas-al ganglia complicated with OSAS in Wenzhou Hospital were divided into control group and respiratory training group with 30 cases in each group.All subjects underwent clinical data registration,and received conventional treatment and rehabilitation.The respiratory training group accepted manual respiratory training in addition,once a day,five times a week,for eight weeks.Before and after treatment,they were monitored to access apnea-hypop-nea index(AHI),maximum oral pressure,average oxyhemoglobin saturation(SaO2),the lowest SaO2,the oxygen desaturation index,duration of lowest SaO2,and time percentages of SaO2<90% and<80%. Results After treatment,the AHI,the maximum oral pressure,the average SaO2,the lowest SaO2and the time percentage of SaO2<90% were better in the respiratory training group than in the control group(t>3.086,P<0.01). Conclusion Respiratory training could improve the respiratory function, reduce the airway resistance, and relieve the nocturnal sleep apnea symptom. It may be one of the rehabilitation methods for brain injury complicated with OSAS.
