FIRST DEXCOM SWIMMING EXPERIMENT #1 :
how exciting. today was my very first day of jumping into the pool wearing my dex sensor. i knew that my receiver would be out of range, no matter where i put it by the pool. its an olympic sized pool, so there was no way that i could be within 20 feet of it at any time. so, i just accepted that and knew to expect the out-of-range icon in the top right corner. no big deal; i didnt let it freak me out.
it felt a little weird feeling the sensor on my arm as i swam, and i was a little bit fearful that it might fall off and that i would be searching for it on the bottom of the pool somewhere; but, that never happened. and, i am pleased to report that not only did my sensor not fall off, but my receiver came back into range within 5 - 10 minutes after i got out of the pool.
this morning when i bolused before turning off my pump, i bolused my usual .5 units, however, i forgot to turn off my pump!!! OMG. i remembered about 1/2 hour later, but then i had that extra IOB when i would normally be jumping into the pool. oh well. no biggy. i could have put off my swim for 1/2 an hour, but decided not to, and if i needed to take some glucose tabs, they would be right there poolside.
todays stats:
1:25 BG 103 took 2 tabs and swam 1/2 hour of slow warm-up laps
2pm BG 157 (oops; oh my goodness; quite a spike from just 2 little tablets
.)swam very hard and fast.
2:30 BG 115 (i guess thats what happens when you swim like a lunatic)
3pm BG 90 (a nice soft landing for 1.5 hours of laps
)
what i have been finding interesting about the DEXCOM is that it is reading about 20 - 30 points lower than my finger sticks, consistantly. right now the dex is reading that my BG is 40, when in fact my finger stick is reading 74. this morning, the dex alarm went off after breakfast and it read 180 with an arrow going up. when i did a finger stick, my BG was 87. i callibrated and soon it came back close within target, but still wonky.
i have heard that the first 2 days, the dex is a little tempermental, and that it should settle in and become more accurate by the 3rd day. so i am trying to be patient with it. clearly, i would not bolus based on its read-outs. it is not to be trusted. now, i dont know if this is a flaw that is inherant in the G4 model. i know that if i find this to be even remotely helpful to my lifestyle, i will wait it out for the G6 model, which seems much more promising. also, Medicare is now covering it, so i will not have to worry about paying OOP.
so thats what today brought. a lot of helpful information. i hope that this dexcom thing works itself out. i could really get into it. but as of now, it is not trustworthy enough to bolus off of.
i read on one of the threads here on FUD that if you had to make a choice about giving up either your pump or your dexcom, you would give up your pump in a heart beat. well, personally speaking, i would never give up my pump, no matter how great the dexcom became. i just cant see that happening.
