The EBI100C Electrobioimpedance Amplifier records the parameters associated with impedance cardiography, cardiac output measurements, thoracic impedance changes as a function of respiration or any kind of biological impedance monitoring.
The EBI100C measures both impedance magnitude and phase simultaneously. Impedance can be recorded at four different measurement frequencies, from 12.5 kHz to 100 kHz.
The EBI100C incorporates a precision high-frequency current source, which injects a very small (400 µA) current through the measurement tissue volume defined by the placement of a set of current source electrodes. A separate set of monitoring electrodes then measures the voltage developed across the tissue volume. Because the current is constant, the voltage measured is proportional to the characteristics of the biological impedance of the tissue volume.
The EBI100C is part of a complete research system solution. This amplifier interfaces with an MP160/MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications, including ICG Analysis.
