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 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. Click below for ICG Analysisvideo...
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.
Output Channels The CH SELECT switch has four bank settings, which assign EBI100C output (i.e. Magnitude or Phase) channels as follows:
Bank
Magnitude (MAG)
Phase (PHS)
1
Channel 1
Channel 9
2
Channel 2
Channel 10
3
Channel 3
Channel 11
4
Channel 4
Channel 12
If a particular EBI100C output is not used, the respective assigned channel cannot be used for another modules output; simply do not record on the assigned but unwanted channel.
