Abstract

Background: Obstructive sleep apnea syndrome is a common disease that is diagnosed by clinical symptoms, signs and by polysomnography or by respiratory polygraphy1. AHI is an index used to assess the severity of sleep apnea syndrome. There are many factors affecting the apnea-hypopnea index. Understanding these factors plays an important role in helping clinicians improve the effectiveness of diagnosis and treatment of obstructive sleep apnea. Objectives: To assess factors influencing the apnea-hyponea index (AHI) in patients with obstructive sleep apnea. Subjects and Methods: A cross-sectional study was carried 57 patients with obstructive sleep apnea syndrome at Tam Anh hospital from march, 2021 to february, 2023. Results: An average apnea-hypopnea index of 35,1 ± 24,16 (n=57). 77,2% of patients have moderate to severe AHI. AHI correlated moderately with neck circumference (r = 0,523; p < 0,001), body mass index (r = 0,359; p < 0,01), oxygen saturation below 90% in total sleep time (r = 0,491; p < 0,01), average SpO2 (r = -0,425; p < 0,01), SpO2 nadir (r = -0,584; p < 0,001). The mean AHI value was significantly higher in supine position compared to in non-supine positions (p < 0,001). Conclusion: AHI is associated with some factors such as: Neck circumference, body mass index, oxygen saturation during sleep, sleeping body posture. Therefore, it is necessary to evaluate comprehensively obstructive sleep apnoea syndrome and to treat promptly patients.
