Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) is a chronic progressive respiratory disease with partially reversible airway obstruction and lung hyperventilation progressing to increasingly frequent and severe exacerbations. The condition is mainly caused by smoking but may result from other causes such as environmental exposure or occupational hazards. Based on Statistics Canada survey data the prevalence of COPD is approximately 4% of the general population, or about 780,000 adults in Canada with 28,000 in Manitoba.
