Chronic obstructive pulmonary disease and sleep

Determination of The Relationship Between Severity of Obstructive Sleep Apnea And Chronic Obstructive Pulmonary Disease

Introduction: Chronic obstructive pulmonary disease (COPD) patients are at increased risk of sleep-disorders. The concomitant occurrence of COPD and obstructive sleep apnea hypopnea syndrome (OSAHS) is named overlap syndrome. This study aimed to evaluate the severity of OSAHS in overlap syndrome patients.Materials & Methods: This cross-sectional study was conducted on adult patients with forced...

Statins and Pulmonary Hypertension in Chronic Obstructive Lung Disease

Chronic obstructive lung disease (COPD) is a chronic multisystem disease with a considerable burden. One of its most common complications is pulmonary artery hypertension (PAH). It has been demonstrated that the development of PAH is correlated with decreased quality of life and survival. Different medications have been proposed for the treatment of PAH, among which one can name statins. Howeve...

Chronic obstructive pulmonary disease and sleep.

The control of breathing in patients with chronic obstructive pulmonary disease (COPD) follows the same basic principles as in normal subjects, both awake and asleep, with an expected lower feedback response during sleep. This impacts nocturnal gas exchange and sleep quality most profoundly in patients with more severe COPD, as multiple factors come into play. Hypoventilation causes the most im...

Chronic Obstructive Pulmonary Disease and Sleep Quality

Coexistence of obstructive sleep apnea and chronic obstructive pulmonary disease

Background: Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) may lead to chronic alveolar hypoventilation. The coexistence of OSA and COPD has been termed the ‘overlap syndrome’. The aim of the study was to determine the relationship between the severity of COPD and the occurrence of chronic alveolar hypoventilation in patients with OSA and to evaluate the impact o...
