| Popis: | Recording of pulsatile blood pressure waveform plays important role in monitoring of functioning of cardiovascular system of patient in medical applications. This study presents simulation of non-invasive sensing to evaluate the physical condition of patient throw measuring continuous cardiac output on radial artery of human. In order to optimize the signal acquisition, the measurement should possess highest sensitivity in the region. Finite modeling and simulation of the arterial network of human forearm is described in this work. The spatial sensitivity of four-electrode system for bioimpedance measurements is estimated for different electrode setups and the sensitivity field is described graphically based on FEM simulation. |
