I would say that it depends on the tip position of the Cordis.A lot of times it does not even reach the SVC, so is it a "true" CVP?It seems logical that the more you get away form the SVC, the less accurate it will be? Now, if the difference is clinically significant is another story. Anyone knows about studies done on this?
It is probably a lot easier to transduce via cordis due to its size, you have a better intraluminal fluid column, so your waveform might be better.

Does anyone have the answer about using a subclavian cordis introducer
for monitoring CVP's? Is the lumen size what determises the validity or
the length and position/ Our trauma attending feels it is more
accurate. Thanks
