CVP through PowerPort?

  1. 0
    Can a PowerPort (or any other implanted port) be used to obtain accurate central venous pressure (CVP) readings? Does anyone have experience with this?

    The port is just made so it can handle the injection pressure from imaging dye and doesn't need hep lock flushes.

    Can run thru them fine, we have been.

    if you wanna double check, even bard says you can!

    The link that you provided was for a Power PICC, while the OP is asking about a port- they are two very different things.

    Yes, power contrast injectors can be used on Power PICCs, and also on Power Ports, if they are also accessed with a power needle (different from a standard huber needle). But one also must check to make sure that is a Power port or a Power Picc.

    However, to my knowledge, one cannot obtain a CVP from a port, or any port. My understanding is that the chamber itself interferes with getting an accurate central venous pressure. But you can check with the manufacturers.

    You're right, I misread the powerport as a picc. Had just gotten off work when checking forums heh.

    why not just hook it up to a transducer and see what kind of waveform you get?

    Just because you get a waveform, does not mean that it is accurate.

    i would plug it in and see what you get, of course the wave form should be smooth enough for you to recognise the a wave and z point and try to get a manual mean cvp reading and compare to the monitor readings. keep in mind that the readings should conicide with whats going one with your pt.

    Considering the placement difference between a port and the distal end of a CL, I highly doubt that you can obtain a CVP from a port.

    called a pal of mine that works at another icu, he claims they have used picc lines for cvp readings in the past at his hospital.

    You can use a picc line for a CVP but you could not say it was a right atrial pressure. The picc terminates at the svc. I have never seen an implanted port (I.e. Port-a-cath)
    Used for CVP's.
