Patients with chronic obstructive pulmonary disease (COPD) and other respiratory illnesses are more at risk of getting COVID-19. Lung function tests, such as spirometry and plethysmography, are often used to determine how well the lungs are working. These tests measure lung volume, capacity, rates of flow, and gas exchange. Information from these tests is helpful to clinicians to diagnose and determine the appropriate treatment for patients suffering from lung disorders.
