You can sit upright with no restrictions around your chest. You can also stand, but the important thing is that you are straight with your chest. Before performing the forced expiration, breathe normally for a few seconds, then take a deep breath with the mouthpiece and wrap your lips around the mouthpiece, followed by a further quick, full inspiration expiration.
It is important that you blow as fast as you can and until no more air comes out.
After going through the troubleshoot section, should the device not work properly please send an email to email@example.com explaining what the issue is.
The grading is based on how well the tests are performed and how reproducible they are.

- The difference in FEV1 between the two best tests is no more than 150 ml.
- (Also known as A and B).
- At least 2 acceptable tests.
- The difference in FVC between the two best tests is no more than 200 ml.
- The difference in FEV1 between the two best tests is no more than 200 ml.

The app shows if your lung tests indicates:
- Normal lung health
- Mild obstruction
- Severe obstruction
- Moderate obstruction
- Restrictive airways
Obstruction indicates that the airways are partially blocked, so the air will come out slower. You can simulate this by blowing out through a straw.
Restriction means that the total lung volume is too low. Although an accurate diagnoses of total lung volume is not possible with spirometry (residual lung volume cannot be measured with a spirometer) spirometry results can be very suggestive for a restrictive lung disease.
