Spirometry Testing is a standard lung function testing method that evaluates how well your lungs perform by measuring how much air you can breathe out in one forced breath. The spirometry is done by using a device called a spirometer.
Conditions that can be picked up and monitored using spirometry include:
The tests are repeated several times to make sure the results are accurate.
During the test, you will be standing upright, and you will be given a mouthpiece connected to the spirometry machine. The procedure is then as follows:
This maximal effort is very important, and testing will be repeated at least three times to get the best results.
The measurements will be compared with a normal result for someone of the same age, height and sex, which will help show if the lungs work properly or if there is an obstructive (such as asthma and COPD), restrictive (such as pulmonary fibrosis) or a combination of the two.
Risks and side effects
Spirometry is generally considered safe. Common experiences during the tests are feeling dizzy, shaky, or tired.
Spirometry may not be safe for people who have uncontrolled high blood pressure, people who have or recently had unstable angina, a heart attack, an operation to the head, chest, stomach, or eyes. For this reason, a screening will be done before commencing with the spirometry testing.
