What you need to do before the test?

  • Wear comfortable clothing.
  • Ideally you should not use your inhalers before your spirometry. There are different types of bronchodilators; some are  long acting and others are short acting inhalers so ask your doctor how long you should avoid using your inhaler/s before the test.
  • If you experience breathing problems before your test, go ahead and use your inhaler/s. Inform the person performing the test the name of the inhaler/s you used, dosage/puffs taken, and the time you used them.
