Sleep Disturbances in COPD are Associated with Heterogeneity of Airway Obstruction
Individuals with Chronic Obstructive Pulmonary Disease (COPD) experience sleep disturbances due to the impact of respiratory symptoms on sleep quality. We explored whether sleep disturbances in COPD are linked to heterogeneity of airway constriction.The impact of breathing problems on sleep quality was measured in consecutive COPD outpatients with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Impulse oscillometry technique (IOS) was employed to assess heterogeneity of airway constriction. Subjects with a previous or concomitant diagnosis of asthma or obstructive sleep apnea (OSA) were excluded.Fifty COPD subjects (M/F 40/10; age: 71 +/- 8 yrs, Body Mass Index (BMI): 26.2 +/-…
Relationship between sleep disturbances and peripheral airway abnormalities in COPD patients
Background: Individuals with COPD experience sleep disturbances due to the impact of symptoms on quality of sleep. Aim: To test the hypothesis that, in COPD, sleep disturbances are linked to peripheral airway abnormalities. Methods: An investigational study is being performed at the University of Palermo, Italy. The impact of breathing problems on quality of sleep during the previous week is measured with the COPD and Asthma Sleep Impact Scale (CASIS) questionnaire. Airway resistances by impulse oscillometry (IOS) assesses peripheral airway abnormalities. Lung function evaluation includes static and dynamic lung volume measurements. To rule out the risk of having obstructive sleep apnea, th…
