Summary

The role of continuous non-invasive arterial pressure (CNAP) in high risk patients with pronounced variation of arterial pressure will be assessed under analgosedation.

Therefore, patients will be analyzed during normo-, hypo- and hypertension with standard IAP undergoing elective transfemoral aortic valve implantation procedures. Systolic, diastolic, and mean invasive arterial pressures (IAP) will be compared to those obtained by CNAP. Data will be analysed in different periods of arterial pressure for agreement of the two methods and for determination of precision (i.e. measurement error) and accuracy (i.e. systematic error). Additionally, we will compare both methods regarding the amplitude and time of very fast changes in arterial pressure during intervals of functional cardiac arrests (rapid pacing).

Conditions

  • Transfemoral Implantation of Aortic Valves

Interventions

OTHER

different blood pressure intervals

In differnent blood presure intervals the IAP and CNAP measurement differences will be observed.
