You know what Jamey,if I remember correctly, Toronto hospital does. I don't remember the particulars on the how to. But, I am sure I read something along the way somewhere(sorry to say I don't do it).

MemberHere's what I know for what it's worth: it's more of a verification than a calibration. Using water, measure the deadspace ( where the hose attaches to the cylinder ) by pulling the plunger back, filling with water and emptying it into a graduated cylinder to determine DS. Then with plunger at max, fill with 3 liters of water and empty into a graduated cylinder.Measure total volume and subtract volume of DS and the remainder is the 3 L (or close to it ). Thus far in our lab, it's been pretty accurate.

Hi Jamey,
Mary Ann is right, you can calibrate your "pre-calibrated" syringe with water. You will need water that is room temperature, and graduated beakers or cylinders of different sizes.
Most suppliers of PFT equipment should be able to point you to services that will calibrate your syringe for you. They charge somewhere around $100 to do it.
