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

    I work in a SICU/CVRU and we use PICCs for CVP readings.

    Here is a question for you guys.. We had a renal patient come to us after coding in dialysis. The only access the patient had was a temporary HD cath (Which had been accessed in dialysis and was running IVF upon arrival) The HD cath had not been hep locked and the Renal MD, who was on the floor, wrote an "OK to use HD cath" order. Due to hypotension a CVP reading was requested. Anyone used HD cath for CVP readings?? My guess would be that it would be inaccurate due to the location the tip terminates but the Critcal Care MD said to use it anyway. Any feedback?

    Often times we will transduce whatever venous access they have even though it might not be a true CVP. We'll transduce to just look at the trend (not necessarily the number) to see if we are headed in the appropriate direction until we can get a definitive line placed.

    I have done it but it depends on insertion site & where tip terminates. We use a lot of jugular sites

    the tip termination is not such an issue for me. as far as what meandraggonbrett stated, i too am a firm believer in watching the trending of the values and treating the direction they are heading. we use femoral lines for cvp readings and that tip is about as far from rt atrium as can be. just my humble opinion.

    Research has shown that CVP readings through a PICC line are reliable, though they may vary by one or two points. In addition to checking with the manufacturer, you could also look at your units policy and procedures, or speak with your unit CNS if you have one
