Accuracy and Precision of Noninvasive Measurement Clinical Trial
Official title:
Accuracy of Continuous Non-invasive Arterial Pressure (CNAP) With Invasive Measurements Dependent on Cardiac Function, Vascular Resistance and Volume Status
Agreement of CNAP pressure with invasive pressure is evaluated dependent on hemodynamic
variables achieved by a PICCO monitor.
Hypothesis: Low cardiac output and volume status but not high vascular resistance affect the
accuracy of CNAP.
Agreement of CNAP pressure with invasive pressure is evaluated dependent on hemodynamic
variables achieved by a PICCO monitor.
Hypothesis: Low cardiac output and volume status but not high vascular resistance affect the
accuracy of CNAP. Body mass index and age may have impact on the accuracy of PPV measured
non-invasively on the basis of volume-clamp technique.
