is it 0.39cc's?

The first question is a little over my head yet,sorry. I haven't had to figure weights into it yet.

Are all your heparin bags the same concentration? When we went to the standard of 10,000 in 1000 all of a sudden heparin drips became easy as pie.

In answer to the first question, I dont think you have to use the weight, that is in there to throw you a bit I think. All she wants is the pump setting!!!!!

And yes 0.39 is correct,

I did just throw the weight in as a "little extra". Although we do use weight based protocols to figure the dosages, we don't use them to figure up the cc/hr on the pump.

A trick they showed me when I started working was to just double the units/hr. If they want 1200unit/hr the pump will run at 24cc/hr. It works! Thank god, b/c I hate math:)

Ack! That weight thrown in there for good measure just took me back to my days in nursing school and I experienced a horrible flashback thanks to you!!!

Thanking God I got out alive,
