• Frequently Asked Questions – Connecting a spirometer

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’?

Normally, our app will automatically select your best valid measurement. But if the spirometer decides that your measurement wasn’t valid, Project Breathe App won’t let you save it.

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.

Why does my spirometer display not match with the numbers in Project Breathe?

The Vitalograph spirometer is factory-set to display PEF as its first measurement. Scroll through the display screen using the right hand (arrow) button next to the screen, and you will find your FEV1 measurement. This value should match the figure recored in Project Breathe App.

What do the icons on my spirometer mean?

Here are the commonly seen icons, or symbols on the spirometer:

If the image displayed on your device is not found in the above image, you can obtain further information in the online manual, found at: https://vitalograph.co.uk/downloads/view/29 .

My spirometer has disconnected but I have only taken one measurement, what should I do?

You can save that measurement if you wish to, or you can dismiss the capture page via the cross in top right hand corner and begin again.
