Our small IR nursing staff has recently added CT IVs to our scope of practice. We are concerned with the IV equipment used with the power injectors. IV catheters are fine - Protect IVs are ok to 300 psi but we attach this to a microbore extension set as the IVs are started in an area away from CT. I can find nothing in package inserts or on line that identifies pressure tolerances for these T-connectors, extensions sets etc. Anyone found a product that is acceptable?
