Pulmonary Function Tests (PFT)
What Are Pulmonary Function Tests (PFTs)?
PFTs, or pulmonary function tests, are also known as lung tests. They indicate how well your lungs function. They are noninvasive, meaning the doctor does not cut you or insert instruments into your body.
Spirometry is the most basic examination. The amount of air the lungs can contain is determined by this test. The test also measures the ability to forcefully expel air from the lungs.
Spirometry is utilized to check for lung volume-affecting disorders. Additionally, it’s utilized to check for conditions like COPD or asthma that affect the airways.
Another common lung function test is lung volume testing. It measures the volume of air in the lungs, including the air that is still present after a typical breath and is more accurate than spirometry. A diffusing capacity test also gauges the ease with which oxygen enters the bloodstream. Exercise testing aids in identifying the reasons for breathlessness. When the findings of the standard breathing test are normal, there are further tests to determine if the patient has asthma.
Why Are The Pulmonary Tests Performed?
Lung examinations can help physicians diagnose lung illnesses such as:
- Chronic bronchitis
- COPD or chronic obstructive pulmonary disease (COPD)
- Lung scarring or damage
- Sarcoidosis, a cluster of inflammatory cells surrounding organs
- Lung cancer
- Airways that are thickened, stretched, or enlarged
- Connective tissue thickening and stiffening (scleroderma)
- Lack of strength in the chest wall muscles
A diagnosis is necessary for proper treatment.
What To Expect?
These examinations are painless. They are administered by a pulmonary function technologist, who will instruct you to exhale and inhale with maximum effort. Multiple tests are conducted to ensure that the results are accurate. When conducting the test, keep in mind the following:
- Unless instructed otherwise, you should take your daily prescriptions prior to testing.
- Do not smoke for a minimum of six hours before testing.
- If feasible, do not use a short-acting inhaler for six to eight hours before a test if you are using one.
- Your physician may provide you with additional medication instructions.
You should plan to wear loose-fitting, comfortable clothing and athletic shoes for the exercise test, which will be completed on a bike or treadmill.
You will be connected to a heart monitor and blood pressure metre during the test to check your vital signs and will receive additional preparation instructions for this exam at the time it is ordered.
