CGM and diving

[jpip]

I think that bluetooth might work from a wetsuit (or dry) to a phone in a housing. I am diving this week but can see if it works when I get back to the lab.

Did you manage to try this in the lab?

Regarding bluetooth underwater, I wonder if smart watches with (basic) dive computer capabilities, and also CGM support-such as the Garmin Fenix series, or the Apple Watch Ultra-will work underwater to give continual CGM readings. Someone here must have already tried this.

We tried it but didn't work well at all.
Time to try it in the ocean.

If I understand correctly, the issue is that bluetooth signal does not propagate well underwater.

So, I was thinking in my particular case, if the reading device (cellphone, watch, ...) is inside the dry suit, I could still receive signal from the sense. The problem is that I cannot see the reading, but I could try with one of these (or both):

1. Play a loud alarm if glucose levels drop under a certain level (sound propagates well underwater).
2. If I had a spare dry suit that I'd happy to potentially destroy, I could cut out a piece from the forearm, patch a transparent plastic with glue, and place my phone / CGM device so that I can read the current glucose level next to my dive computer.

I am diabetic type 2 and use a constant glucose monitor (CGM). Before I went to Cozumel, I searched to see if a CGM works after scuba diving. I didn't find any information.

I am glad to report that my FreeStyle Libre 2 sensor continued to work after 5 days of diving (2 dives per day). The deepest depth was about 90ft. I was wearing a shortie.

Hello I have had no problems diving with my CGM I just started on Ominipod and stop using it for my recent dive trip. I was wondering what the best pump is for diving in the future?

The Omnipod is a pump/CGM combo. I would recommend you check with the manufacturer before diving with it. Devices like this are not always compatible with pressure.

I put a IV3000 over my Dexcom and another my Omnipod5, my pod failed after my second dive of the day, but my Dexcom GTG, the next day 2 more dives and same results, Dexcom GTG and Omnipod failed on second dive, BG never went over 200. I am a Aircraft Mechanic for a Airline, so I hate pumps with cords, even if there a better pump more suited to diving, I wouldn't change from Omnipod.

I would be cautious (OK I wouldn't do it) on diving with a pump on. If there are air bubbles in the catheter or reservoir (and there are always bubbles) you will get a bolus of insulin you weren't planning on. CGMs are a totally other story, they (with caveats) are mostly fine diving. I have dived with both Libre and G7 and both were fine.
