I guess it's a trick. :-)
1. I pull out the syringe plunger all the way and push it back in. Then I
pull it out about 40 units.
2. I push 40 units of air into the Velosulin bottle, draw out Velosulin,
and fiddle with it and the air until I think I've gotten rid of the
bubbles and have 40 units V in the syringe.
3. Then I insert the syringe into the H bottle and pull back the plunger
until I have a total of 160 units of insulin in the syringe.
I don't get any extra air in the syringe while drawing the H. You could
stop here. But:
4. I draw in 50 or so units of air, swish it around a few times to make
sure the H and V are well mixed together, and then push it out. I only
see the one big air bubble doing this, not little bubbles, so it's
pretty easy to get rid of it. I usually lose a little insulin while
ejecting the air, so I have about 150 units in the syringe now.
5. I connect the new tubing and fill it from the syringe. Then I put the
syringe in the pump and continue as I did when I didn't mix H and V.
You can use however much of each insulin you want, and in whatever
ratio. The main trick is that I get all the air out with the FIRST insulin,
and don't let bubbles in with the second vial.
