Spirometry Findings in Patients with Chronic Obstructive Pulmonary Disease
Introductions: Clinical diagnosis of chronic obstructive pulmonary disease isÂ often not accurate and treated for prolong duration. This study explores the useÂ of pulmonary function test to confirm the diagnosis and further managementÂ of such patients.
Methods: This was a cross sectional study conducted at Patan Hospital, PatanÂ Academy of Health Sciences, Nepal. All patients coming for spirometry betweenÂ June 2012 and May 2013 with the clinical diagnosis of chronic obstructiveÂ pulmonary disease were enrolled in the study.
Results: Out of 338 patients with clinical diagnosis of chronic obstructive
pulmonary disease that underwent spirometry, 80 (23.7%) patients had ratio ofÂ forced expiratory volume in one second and forced vital capacity less than 70%.Â Out of these 80 patients, 50 (14.8%) had irreversible airway obstruction andÂ 30 (8.9%) had reversible airway obstruction. Patient with normal spirometryÂ findings was 258(76.3%).
Conclusions: Clinically diagnosed chronic obstructive pulmonary disease isÂ best confirmed by spirometry for optimum management.
