we stopped using them because the numbers were unreliable esp in septic patients, but we also really got away from swans too. I remember when we were putting in S/Gs with CCO at a drop of the hat but every since that study come out about bad outcome with swans the numbers have dropped. i work in a teaching hospital and the last time i had a patient with a swan was at least 6 months ago

"literature supports the use of SVV only on patients who are 100% mechanically (control mode) ventilated with tidal volumes of more than 8cc/kg and fixed respiratory rates"
We rarely use control mode in our unit.
We recently started using the Edwards FloTrac for our Triple H patients. The first round went really well, the second round did not go as well. The problem we are having is the variability with the numbers. We are following the Stroke Volume Variation (SVV) instead of the Stroke Volume Index (SVI). I am wondering if anyone else is using this to monitor fluid status for your Triple H patients and what are your parameters for treatment? Do you follow the SVV or the SVI? I would rather not go back to our pulmonary artery catheters, but if we can't find a solution that will be what is necessary.
we use flo trac all the time and we love it! We use SVV and shoot for less than 9 but mainly we watch SI, SV, CI and good ol CVP via central line. We dont always set parameters besides SBP parameters for our HHH pts. sometimes we will have a cvp parameters though. We havent used swans in forever.
if variation isper the Edwards (http:;;http://www.edwards.com/products/mininvasive/strokevolumevaritaionwp.htm) it says normal values are 10-15%..with a usual goal of LESS than 13%...so the higher the number the drier the pt. is how i'm taking that. I know we aim for 9 in my neuro icu. But less than 13 should be good. I mean 13 might kinda ride the line but less than 13 shouldnt be dry.
An update: we are seeing great success using the Flotrac. Our goal is SVV40 and CVP>8 for non-vented and >12 for vented patients. If two of the three parameters are not in range we bolus the patient. No more swans...YEAH!
Just recently had a patient who spasmed for the full 21 days, several trips for IA Verapamil and she walked in to visit us completely intact. Really makes you feel good about what you do!
