It seems that every post-surgical heart patient i have received since we have gotten the new edwards monitors has had an issue with monitoring mixed venous oxygen saturation (svo2).The svo2 initially reads, but after a while, the monitor alarms and the error message, "fault: oximetry cable temperature" pops up.I have tried with this patient, as with others, to unplug and re-plug the cord for the svo2.When you try to go into the "oximetry calibration" menu, all of the options are greyed out, so the monitor doesn't even give the user the option of recalling data or recalibrating.The issue has been in multiple rooms with multiple monitors.Manufacturer response for hemodynamic monitor, edwards lifesciences, (per site reporter).The vendor is aware and is reportedly working on a software update to remedy this problem for the last few months.
