Lung function tests (Spirometry | Peak flow meter)

Spirometry is a tool that measures how effectively your lungs are working. It can show how much air lungs are able to hold (their volume) and how much air can be breathed in and out (inhaled and exhaled) which is called flow. It can be used to diagnose problems of breathing and monitor the usefulness of treatment. The test involves taking a deep breath in and blowing out as hard as you can into a hollow tube attached to a spirometer machine. You will be asked to do the test several times. The whole process takes 15 - 30 minutes depending on whether you are given some inhaled medicine and asked to do it again to monitor if there is an improvement.

Peak flow meter This is a small hand-held tube that can measure what is happening in your breathing tubes. You can have one at home and measure your peak flow by blowing into it as hard and fast as possible. You will be shown how to measure it and compare it with what you can blow when you are well as part of your asthma management plan if you think you are having an asthma attack.
