Treatment Check

This tool is created to support you in your self-management. With the help of our spirometer and symptom reporting you receive a suggestion of your asthma control. If you have a treatment plan from your healthcare provider, it will be linked to your control.

How often should I do a treatment check?

This is decided by your healthcare professional. To achieve optimal effect of AsthmaTuner, it is recommended to test yourself at least once a week, but preferably once a day.

How do I perform a treatment check to get a treatment recommendation?

AsthmaTuner’s self-management is divided into a few steps, Lung function, Symptoms, Treatment Recommendation. Start by clicking new test on the home screen

Lung function

  • Make sure the ‘Treatment’ tab is selected in the app’s home screen
  • Click ”new check”
  • Follow the instructions in the app to connect the lung function meter
  • When connected, the test starts automatically
  • Follow the on-screen instructions to perform a lung function test
  • After completing the test, you can select “Retry” or “Save”
  • Important! Be sure not to cover the turbine with your hand when doing a test, make sure you create a tight seal with your lips and blow out as hard as you can from the start.
  • Important! If you blow a higher value than your previous tests, the app suggests updating your personal best value. This controls your treatment recommendation so only update it if you have correctly performed a test yourself.
  • NOTE: If you have difficulties with or do not have a lung function meter, you can choose to skip directly to the next step.


Register your symptoms for the past week by answering Yes or No to the four symptom questions. If you would like to read more about what each question means, tap ‘What do these asthma symptoms mean?’ When you are satisfied with your answers, click ‘Save’

Treatment recommendation

Based on your lung function and or reported symptoms, you now get a recommendation on which asthma control you have – green for controlled, yellow for partially controlled and red for uncontrolled. The treatment recommendation is dated and valid for 24 hours or until a new test is performed. The criteria for determining whether you have controlled, partially controlled or uncontrolled asthma follow international guidelines and are based on a comparison of personal best FEV1 with the current measured lung function value and by looking at the number of symptoms reported.

If you have a treatment plan from your doctor, you will also see which medicines to take and any further instructions from your healthcare provider.


As a final step, you can choose to go directly to your home screen or add triggers. Choosing triggers gives you the opportunity to record what you think triggered your asthma and leave a comment.

My Asthma

On the home screen, you can click on ‘My Asthma’ to see your historical values. Information about asthma control, lung function, symptoms and registered triggers is shown here. You can choose to view triggers and other information for a specific time period.

Evaluation Tool

The evaluation tool is created to assess how your lung function varies over time. This can be an indication that will help for healthcare professionals to determine if you have asthma.

How long is an evaluation period and how many tests should I perform?

An evaluation period is normally 2 weeks. During these two weeks, you should test your asthma every morning, afternoon and when you experience symptoms.

The home screen shows how far you have come in your evaluation period. Only complete days with at least 2 tests are counted. If you miss a day, the evaluation period is extended.

Tip! Don’t forget to set reminders so you remember to do your tests

Important! Duration of evaluation period and number of tests may vary. Discuss and follow your healthcare provider’s recommendations.

Perform an evaluation test

A test consists of checking lung function and recording of complaints. Start the test by clicking on the new test on the home screen.

Evaluation test

  • Make sure the ‘Evaluation’ tab is selected in the app’s home screen
  • Click “new evaluation test” Follow the instructions in the app to connect the lung function meter
  • When connected, the test starts automatically
  • Follow the on-screen instructions to perform a lung function test. You need to do 3 correct tests to proceed to the next step
  • Important! Be sure not to cover the turbine with your hand when doing a test, be sure to create a tight seal with your lips and blow out as hard as you can from the start.

Register symptoms

  • Answer all questions in order to save
  • Select any symptoms you may have experienced
  • You can also add additional information in free text


If you click on evaluation history, you will see a summary of the period with the highest and lowest test so far as well as details about all the tests. You can change previous comments by clicking on the text box during a test and then tapping save.

Spirometry Tool

The spirometry tool is another way for caregivers to assess a patient’s lung function. This test provides caregivers with a larger set of values as well as a spirometry curve plotted in a graph. Forced Vital Capacity (FVC) is one of the values unique to this type of test.

When your caregiver requests this type of test, they can choose between two types of spirometry testing: with or without reversibility. Reversibility testing is a specific type of spirometry that is done specifically to evaluate the difference in lung function before and after taking asthma medication. Only caregivers can activate the reversibility feature from Careportal, it is not possible to do so from the AsthmaTuner app.

Important! Never perform a spirometry with reversibility unless a caregiver has specifically instructed you to do so and given you clear instructions for taking the asthma medication needed for this test.

Perform a spirometry test

Regular Spirometry Test

  • Make sure the ‘Spirometry’ tab is selected in the app’s home screen
  • Click “new spirometry test” Follow the instructions in the app to connect the lung function meter
  • When connected, select ‘Start test’
  • Follow the on-screen instructions to perform a spirometry test. It is recommended to do 3 correct tests in order to ensure acceptable test quality, but your caregiver may ask for fewer or more tests

Important! Be sure not to cover the turbine with your hand when doing a test, be sure to create a tight seal with your lips and blow out as hard as you can from the start.

Tip! It’s common for patients to feel like your air runs out very early in the test, but don’t remove the spirometer from your mouth until the ringing sound in the app stops.

Reversibility Test

  • Make sure you have gotten clear instructions directly from your caregiver about which medication to take for this type of test and how to take it correctly. This is a vital part of the test and the app alone will not provide this type of information.
  • Make sure the ‘Spirometry’ tab is selected in the app’s home screen
  • Click “new reversibility test” Follow the instructions in the app to connect the lung function meter
  • When connected, select ‘Start before-inhaler session
  • Follow the on-screen instructions. It is recommended to do 3 correct tests per session in order to ensure acceptable test quality but your caregiver may ask for fewer or more tests
  • When you have completed the ‘Before-inhaler session’ it’s time to take the caregiver recommended inhaler.
  • Pressing “Taking inhaler now” will start a timer that allows 15 minutes for the medication to take effect.
  • Wait until the timer runs out
  • When the timer has run out, complete the “After-inhaler session” in the same way you did the previous session.
  • Press “Save” – you have now completed the entire reversibility test

Tip! 15 minutes is a long time to wait between sessions. It’s okay to leave the app while you wait but switch on notifications for the AsthmaTuner app to receive a reminder when it’s time to continue the testLung function measurement and the spirometer.

General about spirometry

Spirometry is performed for diagnosis of symptoms such as shortness of breath, protracted coughing and wheezing, and protracted respiratory symptoms. Furthermore, spirometry is performed to follow the effect of treatment and follow disease and for general control of the health of the lungs.


FEV1 – “Forced expiratory volume measured in one second”, is the volume of air that can be exhaled in one second with maximum force from fully filled lungs. Exhalation should start explosively with the highest speed from start to finish. This measure is used primarily in the treatment recommendation asthma tool, but also in the evaluation tool.


PEF – “Peak Expiratory Flow”, is the peak flow measured during a test from fully filled lungs. Exhalation should start explosively with the highest speed from start to finish. This value is used primarily in the evaluation tool.


Place spirometer mouthpiece between the teeth without biting down on it. The lips should be closed tightly around the mouthpiece. The tongue is placed so it does not interfere with the airflow into the mouthpiece.


Seated position is the first choice at lung function test, but standing position is also allowed. Make sure your back is straight and lift the chin during the entire exhalation maneuver. Avoid a slouched position.

Nose clamp

The clinic recommends the use of a nose clamp, this is not a requirement for the use of AsthmaTuner.


It is optimal if the spirometry assessment is performed in the same way every time. Repeated tests are ideal for every assessment.


Hygiene should be taken into account in a spirometry examination to minimize the risk of infection between individuals. AsthmaTuner’s lung function meters are personal devices and should preferably not be shared between individuals. For further instructions on cleaning the mouthpiece and turbine see spirometer instructions.

Function control

AsthmaTuner’s lung function meter is factory calibrated, so no further calibration is required. If you suspect that the AsthmaTuner lung function meter is not measuring correct values, the turbine should be cleaned. If this persists, contact AsthmaTuner.
