I have a question that is enough out of the box that I expect no one will have an answer for it. But I figured it wouldn’t hurt to ask just to see what feedback I got.
I’m in the process of switching from a Medtronic 630G pump using their Guardian 3 CGM sensors to a Tandem t:slim X2 with CIQ pump and Dexcom G6 sensors. I’m still using the 630G since (1) I need to set up an online training session with Tandem and (2) I still have unused Medtronic supplies.
I get my medical care & diabetic supplies through the VA hospital nearest to me (Syracuse, NY). How this has worked so far is the doctor at the VA who treats me writes VA prescriptions for the pump & CGM. Then, after some internal paper shuffling, the VA ships the pump & CGM supplies to me.
The point I am trying to make here is that I never actually deal directly with either Tandem or Dexcom. Their sales’ departments don’t really know me as I never place an order for anything with either company. The companies deal directly with the VA not with me. The VA is their customer, not me.
The VA has shipped me a Tandem t:slim X2 with CIQ pump and the supplies to use that pump. The VA has also shipped me Dexcom G6 sensors and two Dexcom G6 transmitters. The VA did not ship me a Dexcom G6 receiver. So the only way I have to monitor the data from the G6 CGM is via the Tandem pump.
Note: I can not use the Dexcom G6 app as a receiver for the G6. My phone is an Android Motorola Moto G7 and the Dexcom app refuses to work on it.
I suppose I could just fill up a t:slim insulin cartridge, slam on a Tandem infusion set and then have at it. But I would prefer to try out the G6 CGM first. Then, after getting a feel for using the G6 I’d add on actually using the Tandem t:slim to pump insulin.
So I’m wondering if the Tandem pump will still function to monitor the G6 sensors even if it doesn’t have any insulin in it to pump? Anyone out there know?
(One reason I’m not really expecting an answer is because I couldn’t answer this same question if you asked it to me about Medtronic pumps. Although I’ve been using Medtronic’s CGM with their pumps for over 6 years now, I never tried to find out if I could use their pump to monitor their CGM without also using it to pump insulin. One of those things that just “never came up”. Oh, well. )
