COPD Screening Monitor
Spirometry is the most common of the pulmonary function tests, measuring lung function, specifically the volume and/or flow of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachographs, which are helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD. Generally, the patient is asked to take the deepest breath they can, and then exhale into the sensor as hard as possible, for as long as possible, preferably at least 6 seconds. It is sometimes directly followed by a rapid inhalation, in particular when assessing possible upper airway obstruction.
