Dynamic Electronic Filter for Arterial Waveform Distortion

Completed
Conditions
Underdamping/Resonance Artifacts
Registration Number
NCT05166993
Lead Sponsor
University of Florence
Brief Summary

Invasive blood pressure (IBP) is the gold standard for arterial pressure (AP) monitoring in critically ill patients. Nevertheless, IBP may be affected by underdamping/resonance artifacts, that eventually lead to AP overestimation. In these cases, when a pulse contour method is applied, wrong hemodynamic data are also delivered by the monitor. In order to overtake this issue, MostCareUp (a PCM powered by Pressure Recording Analytical Method, PRAM), has been implemented with a dynamic electronic filter (EFMC) that automatically corrects the resonant AP waveform.

In order to test the EFMC, the electronically corrected AP and the derived cardiac output were compared with respective raw data corrected with the Accudynamic, an adjustable damping device specifically manufactured for normalizing the pressure waveform (in our study: the reference method).
