OBSTRUCTIVE SLEEP APNOEA SYNDROME IN PATIENTS WITH CHRONIC OBSTRUCTIVE LUNG DISEASE

Abstract

The paper reviews polysomnography of 83 patients with chronic obstructive lung disease associated with obstructive sleep apnoea syndrome/hypopnoea. The obstructive sleep apnoea syndrome was diagnosed in 62 patients (75 %): there were mild (26 patients), moderate (17 patients), and severe (19 patients) forms of the disease. As reported, there was a reliable correlation between the body mass index, the number of apnoea episodes and the haemoglobin oxygen saturation in arterial blood. There was no correlation related to the forced expiratory volume in one second. Therefore, it could be supposed that the pathogenesis of obstructive sleep apnoea syndrome in case of chronic obstructive lung disease depends on the degree of adiposity rather than the intensity of lower respiratory airway obstruction.
