Abstract
- Background: Obstructive sleep apnea (OSA) is a prevalent sleep breathing disorder affecting 9–25% of the general adult population. Aim: To assess airflow limitation by spirometric indices in patients with obstructive sleep apnea. Patients and methods: This observational case–control study was conducted on 60 subjects who were divided into four groups: Group I (control group), included 20 subjects chosen from other departments, who had no respiratory complaints with apnea–hypopnea index (AHI < 5); Group II (mild group), included 11 patients with mild sleep apnea, 5 ≤ AHI < 15; Group III (moderate group), included 17 patients with moderate sleep apnea, 15 ≤ AHI < 30; and Group IV (severe group), included 12 patients with severe sleep apnea, AHI ≥ 30 at the Chest Department, Faculty of Medicine, Helwan University, from August 2021 until June 2022. Results: There was no statistically significant relation found between the severity of AHI and all the previous pulmonary function parameters except a statistically significant decrease in FEF (25–75%) in the moderate group than the mild group and also in the severe group than the moderate group (p-value < 0.001). There was a statistically significant positive correlation found between AHI and BMI and NC and a negative correlation found between AHI and FEF (25–75%) while no statistically significant correlation was found between AHI and the other studied parameters. Conclusion: Obstructive sleep apnea (OSA) is associated with airflow limitation by spirometric indices, although this association is statistically insignificant. On the other hand, the severity of obstructive sleep apnea is directly proportional to the seriousness of the apnea–hypopnea index (AHI). Strong correlations were found between the severity of AHI and body mass index (BMI), neck circumference, and FEF (25–75%). [ABSTRACT FROM AUTHOR]
