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
