You must sit and breathe into a tiny device known as a spirometer to undergo a spirometry test. This medical equipment keeps track of your breath rate and volume and how much air you exhale. Doctors use spirometry tests to diagnose the following conditions:
- Interstitial pulmonary fibrosis
- Chronic obstructive pulmonary disease (COPD)
- Asthma
- Restrictive lung diseases
Additionally, they let your doctor check on the progress of your current treatment for chronic lung problems. Spirometry is frequently performed as one of several exams known as pulmonary function testing.
The standard procedure of spirometry is the following:
- You'll probably sit during the exam.
- Your nostrils will be kept closed by a clip that will be put on your nose.
- You will inhale deeply and exhale forcefully into the tube for several seconds. To prevent air leakage, your lips must form a tight seal around the tube.
To guarantee that your findings are uniform, you must repeat the test at least three times. You should run the test again if there is too much variation among the three results. The result is calculated using the highest value obtained from three closely spaced tests. It typically takes less than 15 minutes to complete the process.
