“Spirometry” also known as Pulmonary Function Testing (PFT), is the measurement of lung function, specifically by measuring the volume and speed of air that can be inhaled and exhaled.
“Spirometry” is an important tool used for assessing lung diseases such as asthma, cystic fibrosis, and COPD. Results are usually given in both raw data (liters, liters per second) and percent predicted - the test result as a percent of the "predicted values" for the patient's height, weight, age, sex, and race.
