The Relationship between the Severity of Airway Obstruction and COPD Diagnostic Questionnaire Score in COPD Patients
Background & objectives: Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow limitation and systemic inflammation which is also associated with pulmonary and extra-pulmonary complications. COPD Diagnostic Questionnaire (CDQ) is a valid questionnaire that is used to identify patients with COPD. The purpose of this study was to determine the relationship between ...
متن کاملLung hyperinflation in airway obstruction.
*Dept di Science Motorie, University of Genova, I-16132 Genova, Italy. +Division de Pneumologie, Centre Hospitalier Universitaire Vaudois, CH-1011 Lausanne, Switzerland. Since the early studies with inert gas dilution techniques, it has been known that residual volume and functional residual capacity are increased in patients with pulmonary emphysema [1] or acute asthma [2]. These findings were...
متن کاملSmall airway morphology and lung function in the transition from normality to chronic airway obstruction.
This study investigated the relationships between pathological changes in small airways (<6 mm perimeter) and lung function in 22 nonasthmatic subjects (20 smokers) undergoing lung resection for peripheral lesions. Preoperative pulmonary function tests revealed airway obstruction [ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC) < 70%] in 12 subjects and normal lung ...
متن کاملDevelopment of the Lung Function Questionnaire (LFQ) to identify airflow obstruction
OBJECTIVE To describe the item-selection and item-reduction for the Lung Function Questionnaire (LFQ), being developed to help clinicians identify patients appropriate for diagnostic evaluation for chronic obstructive pulmonary disease (COPD) using spirometry. METHODS Item selection and reduction were based on information from 387 > or =40-year-old respondents to the third National Health and...
متن کاملAirway narrowing assessed by anatomical optical coherence tomography in vitro: dynamic airway wall morphology and function.
Regulation of airway caliber by lung volume or bronchoconstrictor stimulation is dependent on physiological, structural, and mechanical events within the airway wall, including airway smooth muscle (ASM) contraction, deformation of the mucosa and cartilage, and tensioning of elastic matrices linking wall components. Despite close association between events in the airway wall and the resulting a...
