The NICO100C simultaneously measures impedance magnitude (Zo; labeled “Z”) and derivative (dZ/dt; labeled “DZ”). Zo and dZ/dt can be recorded at four different measurement frequencies, from 12.5kHz to 100kHz; cardiac output measurements are usually performed at a measurement frequency of 50 kHz.
AcqKnowledge includes automated tools for the automatic analysis of impedance cardiography (ICG), cardiac output and other hemodynamic parameters using noninvasive bioimpedance techniques. The software automatically scores the data and provides tabulated results in either a Journal file or Excel. Click below for ICG Analysis video…
The CH SELECT switch has four bank settings, which assign NICO100C output (Zo and dZ/dt) channels as follows:
|Bank||Magnitude (Zo)||Derivative (dZ/dt)|
|1||Channel 1||Channel 9|
|2||Channel 2||Channel 10|
|3||Channel 3||Channel 11|
|4||Channel 4||Channel 12|
If a particular NICO100C output is not used, the respective assigned channel cannot be used for another modules output; simply do not record on the assigned channel.
