Dual Wave Bolus

I've been pumping since May of 2002. Four years with the MM508 and three years with the MM515. Both pumps have the dual wave bolus feature, I really never use this feature unless there is a high fat content food that I am going to oink out on (the pizza bolus, etc etc...). A few weeks ago, I read a forum post where a TU member stated her pump educator recommended using the dual wave bolus setting for every meal. Her pump educator called the normal bolus a "skittle" bolus, fast acting sugar bolus. Since all of my meals do not contain "skittles" it only made sense to stretch out the bolus time thus giving myself more units over a longer period of time. After reading the TU forum post, I have began using the dual wave bolus for every meal. My numbers have been excellent the entire time. I have dropped my average on my blood sugar meter 15 points. Anyone else use the dual wave bolus at every meal?

this is news to me but wow sounds interesting. Bit to read to understand what you mean but I rarely use mine bolus features either...only for fatty meals which are few and far between really. Haven't been online for ages so will come back to this one. Thanks Danny!

i've used it for every meal since the off. if ever i forget to select the dual wave, the bolus doesn't work for me at all, not that i eat a lot of fatty food, but just because that's my body. AWKWARD. but it's a godsend :')

Jamie - I agree with you. I wish there was a simple explanation for the Square Wave and the Dual Wave bolus.

square wave takes a bolus and devides it over the time you specify
example -- 2.0u over 2 hours = 1u delivered per hour.

Dual wave bolus is where you get an instant bolus plus a square wave
example -- 4.0u dual wave, 2.0u now and 2.0u over 2 hours

The square is good for meals / foods it will take longer to digest (fatty foods, protein, etc). The dual is useful when you have a long digestion meal and also have a good number of carbs in it (pizza is that standard example). Hope this helps.

I'm on a pump since June of this year. Was MDI'ing for the last 20 odd years.
I'm also 10 weeks pregnant with my second baby. When I was pregnant the first time I have a DREADFUL time with hypos. I would go hypo about 2.5 hours post meal. My sugars would be on target 2 hours post food, but I would drop like a stone after that unless I had huge snacks at exactly 2 hours.

Since I have become pregnant this time I ONLY dual wave. Usually 40%/60% and over 1-2 hours depending on what I am eating (fat content, volume etc).
Its a dream. My sugars are constant, predictable, I don't spike as badly and most importantly - I'm not getting those crippling lows.

Dual wave for President :0)
