I asked our CDE and our Omnipod rep, too, but I’m interested to hear what you all think:
Last night, our daughter was 83 at bedtime, so she had some cheese crackers. I gave her 18g, which was probably too much, but I figured better high than low. We didn’t use the PDM, because we’ve just never even thought about bolusing when the point was to bring her up before bedtime.
Sure enough, she woke up at 146. Don’t get me wrong, I’m happy that we were generally in the right ballpark — and as it happens, that’s pretty much bang-on what would be expected using her ratio and correction factor for that hour, so let’s hear it for having nailed the PDM settings, at least for the moment! — but then I realized: we have this great technology, and I bet if we’d told it she was 83 and taking 18g, it would have bolused for the appropriate portion of the snack. She’d have woken up closer to target without going low, and I wouldn’t’ve had to worry about the math when my brain was tired. So,
In the future, should we tell her PDM she’s 83 (or whatever) and tell it how many carbs, and let it reverse-correct at bedtime? (I feel like that’s an obvious “yes,” and we should have known it all along, but I’m checking because what if I’m wrong about that); and
Why is there a range for the min BG for bolus calculator (50-70)? I’m guessing that if you’re under-70 low, you should have juice and get back up into a safe range before you then have a snack that you might bolus for. But if that’s the idea, then why allow it to be as low as 50? Are there times where you’d bolus when you were 50, even while taking glucose?
