    Hi everyone,

    I’ve recently started using the Medtronic 780g + Guardian 3 sensor (my previous pump was the 640g with the same sensor) with the SmartGuard function enabled.

    It seems great for avoiding high levels, but for low levels you can’t seem to have the auto-suspend function on when your BGs go below the range you have set (in my case below 4.4 mol/L), nor can you see on the graph whether any action has been taken to suspend insulin levels (unless I am missing something). With my 640g the auto suspend feature was really useful, so it seems odd that the SmartGuard on the 780g wouldn’t use it too.

    Does anyone know if this pump can indeed auto suspend when in SmartGuard mode, and if so how do you know based on looking at the main screen and graph?

    Many thanks in advance!

    Hi TypeUno. I’m actually on the m670g - your pump’s predecessor.

    I believe the functionality is similar which means your pump should always try and keep you within your target range when in Auto Mode e.g When your glucose levels might be rising your pump will be increasingly giving you micro boluses to try and keep you within range.

    If your glucose levels are decreasing when in Auto Mode then your pump will just stop bolusing and hopefully prevent a hypo. As you will see you may still need to take your own corrective action by taking glucose etc particularly if you’re taking exercise.

    If your pump works like mine then in order to use auto-suspend you would need to turn off auto mode which I think defeats the main reason for having the pump.

    These pumps do have their limitations but are still very capable of giving good control when used correctly - which might take a bit longer for you to achieve until you gain more experience.
