Respiratory Testing



Spirometry is the most important lung function test and measures the maximum amount of air you are able to breath in and out. You will be asked to do this test slowly and fast and it is normal to feel a little light-headed afterwards. Sometimes after spirometry we will give you ventolin and repeat the tests to see if this improves your results.


Full Lung Function Testing

Depending on what the problem is, you may also need to undergo body plethysmography and/or a gas transfer test. Body plethysmography involves sitting inside a closed glass box, like a telephone box, and measures the total volume of your lungs. The gas transfer test measures the amount of oxygen that transfers from you lungs into your blood. During this test you will be asked to take a deep breath and hold your breath for about 8 seconds and then breathe out. For all tests you be asked to wear a soft nose clip and breathe on a mouthpiece. All tests will be repeated several times.
