Lung Function Testing Preparation

Lung Function Testing Preparation 


A lung function test is a series of breathing tests where you will be required to breathe in different patterns through a mouthpiece.  These patterns may require you to breath fast, take big breaths in, empty your lungs out and hold your breath.  The respiratory scientist conducting the test will talk you through each process.  A lung function test is a simple, non-invasive way to examine the lungs and your breathing.

Why am i having this test?

There are many different reasons your doctor may send you to get a lung function test.  Some of these reasons include:

  • To diagnose the cause of a cough or shortness of breath
  • To evaluate the severity of disease
  • As a general check-up for lung health especially if you have had exposure to cigarette smoke or other hazardous chemicals
  • To track disease progression

What do i bring to my test?

If you take any inhalers bring these along with you to your test.  Wear comfortable clothes that will not restrict your breathing

How long will the test take?

The lung function test generally takes about half an hour.  The exact length of the test will vary for each individual.

Could i feel unwell during the test?

During the testing you may feel a little bit breathless.  The tests can also make you cough and lightheaded for a few seconds.  This is normal and you will be given time to recover between tests.  There are no side effects from testing and you will be fine to drive home afterwards.
