Just curious, do very many facilities wedge anymore? I know this topic has been posted before, but it looks like the threads are several years old. We don't personally wedge at my hospital, but I'm curious as to whether it is still commonplace elsewhere. Our CT surgeons go by PAD, CI, and CVP.
Wedging a PA catheter requires a degree of nursing skill that most nurses don't want to bother with. You have to know the waveforms and where in the EKG and respiratory cycle to measure, preferably after you have graphed the waveform on paper. It's usefull information but you have to know how to safely obtain it. Properly done it is an extremely safe thing to do. And even if you don't wedge you should know what the wave form looks like in case the catheter accidently advances to wedge.
Incidence of balloon rupture is 0.03–0.2% of all PA cannulations.

I find this mind boggling and so very sad......

Maybe this is what you meant, but it's not the balloon that ruptures .03-0.2% of the time, it's the pulmonary artery that ruptures. (That's as often as 1/500, which is frequent enough to be of concern in such a severe complication)
We have one cardiologist who will ask for infrequent wedge pressures, but other than that I don't see wedge pressures used anymore for clinical decision making. We usually still get a single wedge pressure on our OHS patients on return from the OR, although it means nothing. Clinical decision making on our open hearts is based on CO/CI, PAs/PAd, SBP/MAP, and SVR (as well as ABG's, labs, etc). We don't figure in wedge pressure or even CVP for that matter.
I agree it's a skill that is being lost, which is always unfortunate, but at the same time if we aren't using the number then we shouldn't be obtaining.
Recognizing a wedged waveform is obviously still extremely important and in my experience that skill is still well honed in those that utilize PA lines, though I could see this being an issue in units with less experienced staff.

My bad.
Our study suggested that the incidence of Swan-Ganz catheter-associated PA rupture is 0.031%...

In my CICU in seems that every chf pt we get has a swan and we get number q6h along with a wedge i
always wonderd if that is outdated or just a different way to practice.
