Measuring Veins for PICC Placement

Hello,

Our VAT measures vein diameter for PICC placement and we have been doing so for some time. However, we have never been formally taught how to do it. So my question is how does everyone else measure? Do you measure side to side vs up and down vs diagonally? Thanks so much! I’ve looked everywhere for formal literature on how to measure and can’t find it anywhere.

Well, they are generally round ... if you are getting a more oblong shape you probably have too much pressure with the probe.

If I'm getting some compression distortion, I measure the shortest distance. If that is "too small" for the device I want to use and I think compression is playing a role, I try to lighten the pressure as long as I can maintain the image. Otherwise, if the shorter distance gives me <33% vein capacity, I don't worry about it since we're just documenting appropriate vein selection and not gathering data for research.

Thanks for your reply. We are from the pediatric world so this practice of measuring has caused a lot of tension with the physicians and our team since we are telling them that we are unable to place a picc line due to the patient not having a vessel large enough. Before we started measuring we would simply eyeball it and figure it would fit.
