How many of you use your numbers from your dex to dose your insulin?
I occasionally do and it all depends on what my BG level is and the situation. I'm starting to do it more now for two reasons. One, I've been on the Dexcom for several months now and I'm gaining more faith in the system and my competence in evaluating my BG readings from the system. Two, I've switched to the OmniPod and it's much easier to bolus than an injection.
The most common circumstance for me lately is when I know I'm going to be eating in a public location and don't want to hassle with doing a finger stick. If I've been fairly stable and I have a chance to finger stick in privacy well before a meal for a sanity check, I will go ahead and take my reading off the Dexcom and just plug in my numbers to the OmniPod PDM and bolus in complete privacy. It's really convenient. I do tend to become a little more vigilant about monitoring the Dexcom, especially if I have to guess at my carb count.
I think the more I get used to the Dexcom/Omnipod combo, I'll probably start doing it even more.
I figure if the meters are only 15% accurate and the Dexcom is good to 20%, I'm only giving up 5% accuracy. With my large insulin doses, a 5% error is far less consequence. Especially now that the OmniPod calculates my bolus to .05 of a unit and my MDI was in single units.
I do it every single day! It is not recommended, and I am not giving medical advice, rather just sharing my personal experience. I've been doing it for 18 months now.
Almost never. If I have a 'good' sensor and am about where I want to be, I'll sometimes just figure the carbs/my I:C ratio and bolus for that. At least it'll keep me where I am, hopefully.
