Objective:We evaluated and compare sleep quality and disorders according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) A, B, C, D groups in patients with Chronic Obstructive Pulmonary Disease (COPD) and to determine sleep disorders.Materials and Methods:Our study included 94 patients who applied to Pamukkale University Medical Faculty Hospital Chest Diseases Polyclinic between January 2016 and January 2017, were diagnosed with COPD according to GOLD criteria, were not in a COPD attack at the time of admission and agreed to participate in the study.Results:In patients with COPD, as the severity of stages increased, a decrease in mean FEV1 values was detected and as the FEV1 values decreased, the mean oxygen values measured during the night decreased. According to the GOLD stage, there was no significant difference between total sleep periods, sleep activity, sleep latency, rapid eye movement (REM) sleep duration, and non-REM sleep duration. According to polysomnography results, apnea-hypopnea index (AHI) was found to be below 5 in 40% of the patients. There was no statistically significant difference between the AHI and COPD stages (p=0.581).Conclusion:No significant difference was found between the COPD stage and AHI severity. However, as COPD stages increased, a decrease in mean nocturnal oxygen saturation was detected. Nocturnal oxygen desaturation is the main cause of comorbidities observed in patients COPD. As a result, careful attention should be given to night desaturation in advanced patients with COPD, and the necessary procedures must be performed to prevent comorbidities. |
