Abstract

Background: Obstructive sleep apnea (OSA) is a condition characterized by repeated pauses in breathing during sleep, frequently accompanied by snoring, daytime sleepiness, and is diagnosed using polysomnography or respiratory polygraphy with an apnea-hypopnea index greater than 5/hour. Objective: (1) To evaluate some biometric characteristics, scores comorbidities on OSA outpatients at the Respiratory Units of Can Tho University of Medicine and Pharmacy Hospital; (2) To survey on respiratory symptom severity, airway obstruction and aerosol treatment characteristics in patients with OSA and COPD; (3) To determine the correlations between the severity of OSA and specific patient characteristics. Methods: cross-sectional, single-center descriptive study. We enrolled 48 outpatients with symptoms as snore, or daytime sleepiness at the RU-CTUMP in the study in three months. Results: 48 patients were divided into two groups with overlapped COPD and risk of OSA (COSA, n = 30) vs. risk of OSA-only (ROSA, n = 18). Overlapped patients had more comorbidities than ROSA patients (Charlson scores of 2.33 and 1.17, respectively). In the COSA group, 100% of the patients suffered from dyspnea with the mean mMRC scores of 2.83 ± 0.75, mean FEV₁ was 60.07 ± 23.09%, and 86% received inhaled medicine. There were significant correlations between the AHI value and the body mass index, neck circumferences, STOP-Bang score, the value of the Snoring Severity Scale, and minimum SpO₂ (r = 0.45, 0.43, 0.46, 0.44, -0.69, respectively). In addition, COPD was a risk factor for OSA (OR = 1.125). Conclusions: OSA is a condition that should be screened for in patients with COPD. Clinicians can use several predictors of obstructive sleep apnea, including BMI, neck circumference, STOP-Bang questionnaire, SSS snoring score to prognosis OSA.
