Analysis for the clinical features and the related factors of obstructive sleep apnea-hypopnea syndrome

Objective: To investigate the clinical characteristics and the related factors of obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods: One hundred and twenty cases of OSAHS confirmed by polysomnography were classified into mild,moderate and severe groups according to the apnea hypopnea index and night SaO₂;and the clinical features of the three groups were compared.Results: The difference was significant among the three groups in terms of age,neck circumference,body mass index,longest apnea time and the index of lowest arterial O₂ saturation(P<0.05-P<0.01).Conclusions: OSAHS can be a great risk factor for public health.Early diagnosis and treatment is essential for the prevention of severe complications of OSAHS.
