Vigileao

Has anyone worked with the new Vigileo monitors? I stepped away from the bedside for 4 months, and then I go to clinical to see a monitor that is connected to an Aline to measure cardiac index. This is new to me. Also, it seems that I am seeing most of the readings as very low...and then there is the SVV (which I had never heard of before).It is the Stroke Volume Variation, which takes into account the variations that occur with inspiration & expiration (for instance pulsus paradoxis).

I was just wondering if any of you have worked with these and if the research shows accuracy and if your practice seems to show accuracy (do the readings point to the actual clinical picture of your patient?).

I just started seeing these monitors, and I do no know if it is because the hospital I was working at prior to this was behind, or that it is brand new everywhere. It seems though, that in the brief clinical rotation I have done (2 weeks), many of these Vigileo monitors are showing extremely low CI readings and SVV readings (although I never knew what an SVV reading was before this clinical rotation).... Do you think the Vigileo is accurate? What if the aline is positional or over-dampened? Surely the readings are affected in this case?
