Assessment of Arterial Dynamic Elastance as a Function Variable of Arterial Load

The goal of the study is to determine Eadyn as a functional measure of arterial load, in conjunction with other actual afterload indices, derived from both invasive arterial pressure tracing and non-invasive signals, such as arterial saturation, non-invasive cardiac output obtained by bio-reactance, and non-invasive stroke volume. A secondary aim is the correlation of the different non-invasive signals with the invasive arterial pressure tracing characteristics.
