Important Reminder: Spirometry Compliance
We’ve recently observed a rise in cases where post-bronchodilator (post-BD) spirometry is not being performed, despite being clinically indicated during initial (pre-BD) spirometry testing.
As a reminder, post-bronchodilator spirometry must be performed on the same day, even if not pre-booked, when any one of the following apply:
FVC is < LLN, or
FEV1 is < LLN, or
FEV1/FVC is < LLN
This requirement is outlined in the Thoracic Society of Australia and New Zealand (TSANZ) and Australian & New Zealand Society of Respiratory Science (ANZSRS) 2024, which you can review here
🫁 Why This Matters
Performing both pre- and post-BD spirometry when clinically indicated is essential to assess for reversibility of airflow limitation, which helps differentiate between asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions.
Failure to conduct post-BD testing when clinically indicated can lead to:
Incomplete assessments
Delayed or inaccurate diagnosis
Potential risk in clearance decisions for workplace health
Please ensure your clinicians are aware of this requirement and that your practice is equipped to complete pre/post Ventolin spirometry when necessary.

✅ Additional Clinical Notes
Ensure bronchodilator administration aligns with recommended agents (e.g. salbutamol 400 mcg via spacer).
Wait time between bronchodilator administration and repeat testing should be 10–15 minutes, as per TSANZ guidelines.
Results should meet acceptability and repeatability criteria (Grade A–C) for interpretation.
Document if post-BD is clinically indicated but not performed, and record the reason (e.g. equipment unavailable, client declined, etc.).
