Noninvasive Cardiac Output Module

The NICO100C Impedance Cardiography (ICG) Noninvasive Cardiac Output Module records specific parameters associated with cardiac output measurements. It incorporates a precision high-frequency current source, which injects a very small (400 µA) measurement current through the thoracic volume defined by the placement of a set of current source electrodes. A separate set of monitoring electrodes measures the voltage developed across the thorax volume. Because the current is constant, the voltage measured is proportional to the impedance characteristics of the thorax.

The NICO100C  is part of a complete research system solution. These amplifiers interface with the MP160/MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications.

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. Watch the ICG Analysis video below.
