Abstract:
The objective of the study was to establish the relationship between functional status of bronchopulmonary system and obstructive sleep apnea in clean-up workers of Chornobyl NPP accident in a remote post-accident period.
Materials And Methods:
We included 58 COPD male patients clean-up workers of Chornobyl NPP accident: 21 with obstructive sleep apnea syndrome (OSA), 37 - without. A complex of functional tests and OSA screening was provided.
Results:
In clean-up workers of Chornobyl NPP accident with COPD and obstructive sleep apnea in a remote post-accident period apnea-hypopnea index (AHI) negatively correlated with FVC, % of predicted (r = -0.36, p < 0.05), the intrathoracic gas volume (ITGV), % of predicted (r = -0.40, p < 0.05); AHI positively correlated with diffusion lung capacity (DLCO), % of predicted values (r = 0.57, p < 0.05), with the intrathoracic gas volume (ITGV), % of predicted (r = 0.53, p < 0.05), body mass index (r = 0.49, p < 0.05) and age (r = 0.62, p < 0.05).
Conclusions:
Obstructive sleep apnea was diagnosed in 36.3 % of patients with COPD clean up workers of Chornobyl NPP accident. Screening for OSA in patients with COPD, clean-up workers of Chornobyl NPP accident is a very important clinical task for prognosis and treatment.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
