What type of doctor does a pulmonary function test?

This test is usually only done by a lung specialist (pulmonologist). It involves sitting in an airtight chamber and breathing in and out of a mouthpiece, like in the spirometry test.

What does a full lung function test involve?

Pulmonary function tests, or PFTs, measure how well your lungs work. They include tests that measure lung size and air flow, such as spirometry and lung volume tests. Other tests measure how well gases such as oxygen get in and out of your blood. These tests include pulse oximetry and arterial blood gas tests.

What is predicted fev1?

A derived value of FEV1% is FEV1% predicted, which is defined as FEV1% of the patient divided by the average FEV1% in the population for any person of similar age, sex, and body composition.

How do I know if my lungs are damaged?

What is normal lung function?

It is about 80 percent of total capacity, or 4.8 liters, because some air remains in your lungs after you exhale. Forced vital capacity can decrease by about 0.2 liters per decade, even for healthy people who have never smoked. Forced expiratory volume (FEV1): the amount of air you can exhale with force in 1 second.

When should I see a pulmonary specialist?

Urgent care or your primary care doctor should be your first stop, and then on to an allergist or ear, nose and throat (ENT) specialist.
