Pulmonary Function Test in Pune
Book Now
Pulmonary function tests encompass a collection of assessments aimed at gauging the efficiency with which the lungs inhale and exhale air, as well as their ability to facilitate the transfer of gases like oxygen from the surroundings into the body’s bloodstream.
How the Test is Performed
Spirometry measures airflow. By measuring how much air you exhale, and how quickly, spirometry can evaluate a broad range of lung diseases. In a spirometry test, while you are sitting, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time.
For some of the test measurements, you can breathe normally and quietly. Other tests require forced inhalation or exhalation after a deep breath. Sometimes you will be asked to inhale the substance or a medicine to see how it changes your test results.
How to Prepare for the Test
Do not eat a heavy meal before the test. Do not smoke for 4 to 6 hours before the test. You will get specific instructions if you need to stop using bronchodilators or inhaler medications. You may have to breathe in medication after Pre-Spirometry.
Why the Test is Performed
Pulmonary function tests are done to:
- Diagnose certain types of lung disease (such as asthma, bronchitis, and emphysema)
- Find the cause of shortness of breath
- Measure whether exposure to chemicals at work affects lung function
- Check lung function before someone has surgery
It also can be done to:
- Assess the effect of medication
- Measure progress in disease treatment
Risks
The risk is minimal for most people. There is a small risk of collapsed lung (pneumothorax) in people with a certain type of lung disease. The test should not be given to a person who has experienced a recent heart attack, has certain other types of heart disease, or has had a recent collapsed lung.
