So, the pool opened last weekend and we just HAD to go. That was the first time with the new Dexcom and swimming. I *thought* it was waterproof, like the OmniPod, so we let him jump in - with the transmitter not the receiver. After about an hour and a half we left the pool and the receiver was ??? for quite some time. I called Dexcom and they said that the limit was 15 minutes in water. I was "Whaaaaaaaa?". She was "Yup". I was like "But at Atlantis we only spend 15 minute OUT of the water." She said that moisture between the contacts of the sensor and the transmitter can get whacked out - which makes some sense I guess. So ... pool season ... what do you guys do? I have some Tegaderm strips that I used to cover his OmniPod so they are PLENTY big enough for the Dexcom but, for some reason, they came off after 1 pool session - maybe they're old or maybe his skin chemistry has changed. I am going to need something that will stay on longer than one day or the pool is going to be a source of great frustration - not that that would matter.
