Spirometry is a diagnostic test that measures how well your lungs work by assessing how much air you can inhale and exhale. A spirometry test is often used to diagnose and monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other lung disorders.
A spirometry test usually takes about 15 minutes. During the test, you will be asked to sit in a chair and breathe into a mouthpiece connected to a spirometer. The spirometer will measure the amount of air you inhale and exhale and the rate of airflow.
Pre-procedure
Before a spirometry test, your doctor will likely take a medical history and perform a physical examination. Be sure to tell your doctor about any lung problems and medications you take. Book an appointment to have the best treatment.
You may be asked to avoid eating or drinking for 30 minutes before the test. You should also avoid smoking for at least 30 minutes before the test.
You should wear loose, comfortable clothing for the test.
Procedure
Spirometry is a diagnostic test that measures how well your lungs work by assessing how much air you can inhale and exhale. A spirometry test is often used to diagnose and monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other lung disorders.
A spirometry test usually takes about 15 minutes. During the test, you will be asked to sit in a chair and breathe into a mouthpiece connected to a spirometer. The spirometer will measure the amount of air you inhale and exhale and the rate of airflow.
The test will begin with you taking a deep breath and exhaling as hard and fast as you can into the mouthpiece. The spirometer will measure the volume of air you exhale and the rate of airflow. It is called the forced vital capacity (FVC).
You will then be asked to take a deep breath and exhale slowly and steadily into the mouthpiece. The spirometer will measure the volume of air you exhale and the rate of airflow. It is called the forced expiratory volume (FEV1). Visit our pulmonology hospital in Bangalore for the best treatment.
After-procedure
After you have completed the spirometry test, the results will be analyzed and interpreted by a doctor or other healthcare professional. The results will be used to diagnose or monitor your lung condition.
If you have asthma, your spirometry test results may be used to determine how well your asthma is controlled. If you have COPD, your spirometry test results may be used to determine the severity of your condition.
You should not experience any side effects after a spirometry test. However, you may experience shortness of breath or wheeze after the test if you have asthma; it should resolve within a few minutes.
Risks involved
There are very few risks associated with spirometry. In rare cases, the test may trigger an asthma attack. If you have asthma, your doctor will likely give you a beta-agonist inhaler before the test, which will help prevent an asthma attack.
Other rare risks associated with spirometry include dizziness, lightheadedness, and fainting. If you experience any of these symptoms during the test, stop the test immediately and tell your doctor.
