Swimming with the Dexcom CGM
As I prepare for my fund-raising triathlon, I've been doing a lot of swimming. One problem that I had to solve was how to swim and monitor my blood sugar at the same time.My Dexcom receiver has to be within 5 feet of the sensor/transmitter. That doesn't work when I'm swimming 1/4 or 1/2 mile distances. While the sensor/transmitter is waterproof, the receiver isn't.
I read somewhere about Aquapac and it's line of waterproof cases, so I measured my Dexcom receiver and ordered their mini class case.
When it arrived it certainly looked big enough for the Dexcom receiver. But when I tried to put the Dexcom into the case, the face would bind to the plastic. So I took a small index card, folded it, and slipped it into the case first. Then I could easily get the Dexcom receiver in place. I use the index card again when I want to get the receiver back out.
When I'm swimming, I use the cord that comes with the Aquapac. I can swim with the cord around my neck, and provided I keep it on the same side as the sensor, I get great readings during the swim. I can also see the values while I'm in the water.For my triathlon, I leave it in the case until the end. That way I don't have to worry about damaging the receiver due to sweat or rain. I've used this case on three long swims (> 15 minutes in the water) and it's worked perfectly.

Hmm, that's a pretty cool solution, and I can imagine how incredibly useful having that data right at your fingertips during that type of activity will be. I'll definitely keep that case in mind should I ever have occasion to take my cgm monitor for a swim too.
My hero! Go, Bernard! I am mightily impressed.
Hi Bernard!
It's Kate from Australia paying a visit to your site...
I would very much like to donate some $$ to your collection for Dr Faustman's trial. I'm wondering what the best way to get it to you is? Any ideas? All I can think of is PayPal,or a transfer to a bank account. If you can think of any other way I can help, whether it be to subscribe to an organisation that you may need an updated subscription on....I'm clutching at straws, I know. I would really like to contribute to your collection-because it is certainly the most exciting D news I have heard in a LONG time!
Tell me what you think...
Cheers,
Kate

Hi Bernard--I did the Title 9 all women's tri in Hopkinton State Park (maxperformanceonline.com). The organizers said it was the only local tri this weekend that didn't get cancelled due to Hanna. Sorry yours was one of them! Good luck with the Maine tri--weekends in September are starting to book up for me, but we will meet at some point, I am sure. And I'm impressed with your underwater handling of your CGMS and pump; I'm still wearing a Minimed 508 and just disconnect it for water events, as it's not waterproof. Good luck in Maine!
