Can anyone give me a ‘starting point’ to a better understanding of when to use the Dual Wave or the Square Wave bolus? When I had my pump training about 6 months ago, the pump trainer was ready to leave and then she said “Oh…I forgot to tell you about the dual wave and square wave…and I don’t have time right now. I will call you later to set up a time for that.” She never called back and now I would like to learn about it. I like my pump which is the Medtronic Revel, but I want to learn how to better understand how this part of it operates. Thank You for any advice you can offer.
dual square(used when you’re eating high carb + high fat meals such as pizza, pasta with heavy cream sauce, and chocolate cake)
first it delivers a part of the dose(50/50 or 70/30) upfront and the rest is extended over a period of time.
it combines both previous types,the normal bolus-first part- covers the carbs and the square bolus-last part-covers the fat.
Thank You to both of you for replying. No problem for me to read ‘copy and paste’ links. And I did read all 16 pages of the link It is a lot of information to absorb, but I will get through it and who knows maybe some of it will sink into the gray matter in my head.
Asma - Your visual graphs should be mandatory reading for Doctors as no one had ever explained that to me…ever! I guess it is no big surprise that my A1C hasn’t been very good lately.
I should read from that link to,to make the information sink in.
as for the graphs,I use them every time someone asks about the boluses ,I got it from Wikipedia.
I like the concept but I have very little luck using them successfully. I usually do multiple boluses to cover the sort of party/ appetizer/ pizza scenarios they suggest square/ dual wave boluses are useful for.
For my dinner this evening I took my mealtime bolus as a dual wave (70/30) over 2 hours. My bg kept rising right up to the 3 hour mark before it started coming down. I am beginning to think that multiple boluses might be a better option for me as well. It is really discouraging to have bg numbers turn out awful when I’ve tried to do the right thing.
