Why is the app asking for my location?
Location ‘permission’ is a requirement for Bluetooth LE and is necessary in order for our app to connect to your spirometer, oximeter and other devices. No data regarding your location is recorded or stored by the Project Breathe app.
Why is my app stuck in a ‘connecting’ state?
If the app gets stuck in a ‘connecting’ state, try closing the capture page and retrying. If this doesn’t help, close the capture page before turning the spirometer or oximeter off and on again, then trying again to record a measurement.
If you are still unable to record a measurement, turn the phone’s Bluetooth feature off and back on again. Try using the phone’s Bluetooth settings page to search for your devices and create a pairing with it. Finally, restart Project Breathe app, you should now be able to record the measurement.
I can not record my best FEV1 measurement, it says ‘invalid reading’?
The Vitalograph spirometer you are using checks whether your measurement is valid. If an exclamation mark ! appears, this means it was not a good quality blow and you should blow again. ! appears when: The extrapolated volume is > 5% or 150mL of FEV6 or a cough is detected in the 1st second. Try again, blow out as HARD, as FAST and as LONG as possible (the device will stop taking readings after 6 seconds). Be careful not to block the mouthpiece with the tongue or teeth. Project Breathe app will automatically select your best valid reading, it will not allow you to record a blow marked as invalid by the spirometer.
I accidentally closed the app before I had saved my lung function, where has my measurement gone?
Project Breathe app will only save a lung function measurement once you have pressed the “RECORD” button. Always try to do three good blows and select to record the best measurement before navigating away from this page.
