View in Spanish: PFP

PFT
A test used to measure how well the lungs work. It measures how much air the lungs can hold and how quickly air is moved into and out of the lungs. It also measures how much oxygen is used and how much carbon dioxide is given off during breathing. A PFT can be used to diagnose a lung disease and to see how well treatment for the disease is working. Also called lung function test and pulmonary function test.
