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.
● Functional residual capacity (FRC).
● Forced vital capacity (FVC).
● Forced expiratory volume (FEV).
● Forced expiratory flow (FEF).
● Peak expiratory flow rate (PEFR).
Normal values for PFTs vary from person to person. The amount of air inhaled and exhaled in your test results are compared to the average for someone of the same age, height, sex, and race. Results are also compared to any of your previous test results. If you have abnormal PFT measurements or if your results have changed, you may need other tests. There are many different reasons why pulmonary function tests (PFTs) may be done. They are sometimes done in healthy people as part of a routine physical. They are also routinely done in certain types of work environments to ensure employee health (such as graphite factories and coal mines). Or you may need to test if you have problems like Allergies, Respiratory infections, Trouble breathing from injury to the chest or a recent surgery, Chronic lung conditions, such as asthma, bronchiectasis, emphysema, or chronic bronchitis, Asbestosis, etc.
PFTs may be used to check lung function before surgery or other procedures in patients who have lung or heart problems, who are smokers, or who have other health conditions. Another use of PFTs is to assess treatment for asthma, emphysema, and other chronic lung problems. Because pulmonary function testing is not an invasive procedure, it is safe and quick for most people.
Stop taking certain medicines before the procedure, Stop smoking before the test. Not eat a heavy meal before the test.
Your height and weight will be recorded before the test. This is done so that your results can be accurately calculated.
