Trans Esophageal Echo

In places I don't have trans esophageal echo, what I've just taken the doing because I am placing arterial lines is simply do a trial and just keep moving a few centimeters to the left a little bit up. And so that works well. You could just do that test if you can place an art line. If it goes up higher, it's probably better, but it may not represent in the opposite situation. The reason that could be happening is that tricular compression contributes to end title CO2, but not as great a contribution to the actual systemic pressures.
