IMPORTANT NOTE about bronchodilator responsiveness and the TSANZ 2022 Spirometry Standards

Did you know that most spirometers are not yet up to date with the new equation to calculate the % change for a bronchodilator response, as per the new 2022 TSANZ spirometry standards?    It is therefore prudent that a bronchodilator response is manually calculated  until your spirometer software is updated when you are performing spirometry to meet the latest 2022 TSANZ spirometry standards for resource sector workers.

Please refer to page 12 of 2022 TSANZ spirometry standards for an example calculation.
