This book provides practising clinicians with the relevant information for the diagnosis and management of COPD patients. Chronic obstructive pulmonary disease (or chronic bronchitis and emphysema) is a common cause of lost work days and ranks high in the list of causes of death. This volume covers all aspects of the disease. After discussing basic science, the emphasis is on the clinical management of these patients. It discusses specific problems, such as sleep problems, and includes recent trends, future perspectives and new developments in therapeutics.
