Hey,

I am a new pumper and I just wondered weather it is worth pimin out a bubble I have in my tubing, it is 4 to 5 milimeters so is hat big enough to need dealing with?

I am going to bed soon so I don't wanna wake up high.

Prime it or leave it?

Thanks in advance!

My vote would be to leave it.

I'd prime it out if you are concerned about it effecting your blood sugars. If you aren't leave it.

clear as mud.

Yeah that is the simple answer lol

How many units are roughly going to be in 4 or 5 milimeters anyway?

[Cyborg]

I use about 40 units of basal per day. For me, I'd leave it...

I did a rough calc of 0.012684989429175475687103594080338 units per mm:

12 units to prime / 43inches of tubing / 2.2 cm per inch / 10 mm per cm. Better triple check that. I'm quite tired.

Menace, you have WAY too much time on your hands.

And does that calculation take into consideration the bends in the tubing deforming the internal volume at the bend? Or that air compresses more than liquid? Or the manufacturing tolerances of the tubing inside diameter? Hmm.

As to the reason for the post, I'd ignore the bubble but if you ever have this happen again (I assume its gone by now), just unhook and prime it out. Not worth even a little stress over it.

Yes, Menace way to much time on your hands.LOL

If it bothers you prime it out.

>start>run>calc takes very little time I didn't even bother rounding it.

My estimates say that bubble costs about 0.04 to .05 units. That's almost nothing for me at meal time, but it would affect me at low basal times where I take 0.45 per hour, roughly 10% of my dose.

It was the lack of rounding that tickled me. Glad it didn't too long for you to generate...
