Hello all. I am taking a class that stated in a sitting/semi-fowlers patient that we have concerns with CPP, we should level the art line at the tragus (or where every you would level your ICP monitor). I have never done that in any of my neuro units. Art was at phleb axis and ICP at tragus and we used those numbers to calculate the CPP. That big of a difference would give you about a 20-30 mmhg difference (lower) pressures. These are huge differences. Anyone doing this? Does it modify your reference numbers for goal cpp?
The only articles I am able to find are ones from journals that state that the transducer should not be leveled to insertion site. I am shocked because I thought that was old news but the research based ones are from 2001 in CHEST. I was practicing back then but it was never taught to me as anything other that the phleb axis.
