What is Spirometry?
Spirometry is one of the most popular yet functional pulmonary function tests. It measures how much air your lungs are able to breathe in and out. The test also measures how fast your lungs can empty the air out.
Spirometry helps diagnose different types of breathing issues, including asthma and COPD. If you are already taking medicines for asthma, Spirometry can help your GP understand how well the medicine is working.
The test needs you to breathe in as much air as possible. After that, you will have to quickly blow out as much air as possible through a tube connected to a device known as a spirometer.The test primarily measures two things:
The amount of air you blow out after inhaling. The results will let you know if you are less able to breathe usually.
The amount of air you can exhale out in one second. The report tells your GP how severe your breathing issue is.
