Spirometry tool

The spirometry tool is available for all lung conditions. You can either activate regular spirometries or Spirometry with Reversibility for your patient. This article describes how regular spirometries work.

Configure the tool

You can activate the spirometry tool for your patient by selecting it when you send instructions.

Choose if the patient should wait for a scheduled appointment to perform the spirometry (assisted) or if they can do the spirometry themselves by simply following the app instructions (solo testing).

Once you’re done you can send the updated instructions to your patient. They will receive a notification and message in the app about their new instructions.

How the patient performs a spirometry test

Whether you chose assisted or solo testing, the spirometry tool looks the same for the patient. Only the instructions displayed above the tool will differ.


To do a spirometry, the patient needs to complete the following steps:

  1. Go to the start page in the app and scroll down to the spirometry tool. If the Asthma Treatment Check tool is active, they may need to switch tab from Treatment to Spirometry.
  2. Tap on ‘New spirometry session’
  3. First-time users will see a guide explaining how the tool works. They will also be informed when it may not be safe to perform a spirometry.
  4. Fill in personal details needed to provide the correct reference values
  5. The spirometer will automatically connect
  6. The patient is recommended to do three spirometries in one session, with rest in between. But fewer or more tests can be done.
  7. Once the session is completed the patient will only have access to the best spirometry result from the session. However, all trials are available in Careportal.


After finishing a session the patient will still have access to the spirometry tool and can perform more spirometry sessions as needed.

Viewing the results

You can view the results from all spirometry sessions by going to the patient page in Careportal and clicking the Spirometry tab.


The latest spirometry will automatically be displayed. You can choose to either view individual sessions or a FEV1 and FVC graph over time.

Individual sessions

For individual sessions, select if you want to use GLI Quanjer reference values or Hedenström. With GLI Quanjer the normal range is also displayed in the spirometry graph. You can view all detailed test information in the list beneath the graph.

Over time

By clicking Over time in the top left corner you can view the FEV1 and FVC values from all spirometries in a selected period. For detailed information on individual spirometries you can click any data point in the graph.


Reproducibility is indicated next to each session. It can be either good or poor.

Copy information

If you need to copy information from any spirometries you can simply select them and click the Copy button at the top of the list. This will copy the date, time, session type, FEV1, FVC and FEV1/FVC from each session with comparisons to reference values.
