Step 2 – Perform a post-bronchodilator spirometry measurement
Ensure your patient has taken their inhaler at least 20-minutes before testing and perform spirometry.
Remember, post-bronchodilator spirometry, or spirometry performed after administration of a reliever inhaler, is the test needed to confirm a diagnosis of COPD.
Once you have achieved good quality spirometry results, record this results in the patient’s notes with the correct code for post-bronchodilator spirometry:
- Read Code: 339m
- Or SNOMED code: 407603001
AND record the FEV1/FVC ratio. This should be a decimal number, not a percentage.
- For example, 0.65
- NOT 65%
- To convert a percentage to a ratio, divide by 100.
At this stage, you will have confirmed or refuted the patient’s diagnosis. Click through the dropdown menu below for more details.
