Spirometry Test

Spirometry is a common test used to assess how well your lungs work by measuring how much air you can inhale, how much you can exhale and how quickly you can exhale.  It can measure how effectively air can be moved in and out of the lungs. Spirometry tests are used as an aid to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. Spirometry  tests can also be used to distinguish between obstructive or restrictive patterns in lung disease.

There are strict standards and required guidelines to be followed in performing spirometry testing. All doctors and staff of OccPhyz who perform spirometry tests are trained and certified. Also our equipment is operated and regularly calibrated in accordance with the Guidelines. All spirometry tests are performed in accordance with the Queensland Health Spirometry (Adult) Guidelines.

Also, OccPhyz Consulting is certified as an approved Spirometry Practice and is on DNRM’s register of health services providers to Queensland’s coal mine workers.

The candidate can prepare for the test by:                                                                                                                               

  • Not smoking for one hour before test
  • Not drink alcohol within four hours of test
  • Not eating a large meal within two hours of test
  • Wearing loose clothing
  • Not performing vigorous exercise within 30 minutes of test

If the candidate has a cold or chest infection the Spirometry test will need to be rescheduled.

Before the test begins the candidate will be asked their Name, Date of birth, Country of birth. These details will be entered into the machine along with their height, weight and sex.

The tester will ask you to breathe through a mouthpiece while wearing a nose clip. The tester will coach the candidate to take in as big a breath as possible. The candidate will then blast the air out as fast as they can for 6 seconds until their lungs are completely empty. The candidate may then be asked to take another deep breath in again. The candidate will do these three times or more to make sure the results are accurate. The candidate may also be given a medication to breathe in. The test would then be repeated after a period of several minutes to show if their lungs have responded to the medication.
