Hemodynamic Readings

  1. Hi all. I am new to critical care, not a new nurse however. I am just learning about hemodynamics: wedge, CO/CI, CVP etc.
    I would like to draw on my fellow nurses considerable expertise in this area for tidbits of info on how the numbers effect the big picture on the patient?
    Thanks

    Hi Phantom,
    Sorry, no short cuts for PA catheters, but think of all the numbers in terms of preload (cvp and wedge), afterload (svri and pvri) and contractility. Look at your numbers, is the preload low, high or normal (remember starling's curve and that we usually would run our patients at the high end of volume loading if they can tolerate it0 and decide if they would benefit from some volume. Then look at afterload and decide if pressors are what the patient needs ( or vasodilators) also remembering that you need to fill the tank or the dop or levo won't be as effective. then look at the CI, does the patient need some kickstarting as far as their pump is working.
    A fellow named Mark Hammerschmidt (I think) has set up a series of on line education things and I'm sure that swans are in there. Look for one of his posts and check it out!
    Hope this has been helpful and not just long winded

    Well, a rather large topic. I suggest you go to the aacn.org website. (American Assoc. of Critical Care nurses). Actually, if you are really interested, I suggest you join. Great association and great resource. I could go on and on about the correct way to measure waveforms (printout vs. readout) But, better than that is the source.

    Best wishe.
