Asked questions

Having trouble seeing spirometry data as a result of upgrading your app to 3.10.0 or 3.10.1? The remedy for this is to delete your app and reinstall it. Make sure you sync all recent data first in your Breathe account settings page. After deleting and reinstalling the app, log into your Breathe account before you do anything else. Once the data sync has completed, check your data is all displaying as you would expect, before adding new data. If the problem is still not fixed, contact your research team for support.

Due to an Android 12 update, some Bluetooth devices need to be set up again in your Breathe RM app, for them to work. Firstly make sure you have the latest Breathe RM app (3.10.1 min), then go to Breathe RM settings and delete your spirometer. You can then re-add the same spirometer and it should once again connect.

Connecting Breathe to any Bluetooth device requires your permission. For devices running iOS version 13 or later, the Breathe application will request the ’Bluetooth’ permission. For Android devices (or Apple devices using iOS 12 or earlier), the app will request the ‘Location’ permission. Note that no data regarding your location is recorded or stored by the Breathe app.

To work with Bluetooth devices including spirometers and oximeters, Breathe requires that you grant the ‘Bluetooth’ or ‘Location’ permission. If you don’t grant permission, then any ‘Bluetooth’th functionality will not work. You can check the status of these permissions within your phone’s settings page. On an Android device, check the ‘App Permissions’ page. On an iOS device, check your ‘Privacy’ settings. On either platform, you should be able to see Breathe in the list of apps that have the permission enabled. On certain Motorola phones, you should also check that you have ‘Find my device’ turned on, in the ‘Location services’ section.

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 Breathe app, you should now be able to record the measurement.

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 recorded in Breathe App.

Breathe app will only save a lung function measurement once you have pressed the “Save” button. Always try to do three good blows and select to record the best measurement before navigating away from this page.

Your spirometer may time out and turn off before you have recorded 3 good blows. If you only have one measurement, you can save that measurement if you wish to, or you can dismiss the capture page and begin again.
