Patient Monitor User Manual Monitoring ICG
- 182 -
On the outside of the box, two LEDs (green and orange) display the current function of the
patient cable, as indicated below:
Green Orange Description of function
The electric part of the patient cable is not connected with the power
supply; cable is disconnected or the device is switched off
Patient cable is ready to use, but the measurement has not been started
Measurement is running; sensor contact is good
Bad contact between sensors and patient: at least one lead wire is
disconnected or not properly fixed; sensors are too dry (eventually new
sensors are necessary)
Insufficient contact between sensors and patient: at least one lead wire is
disconnected or not properly fixed; sensors are too dry (new sensors are
necessary)
Patient cable has power but the module is not ready for measurement

20.4 Precautions and Limitations
With the V-ICG module and the ICG patient cable, you can examine adult patients in a resting
position. The measured parameters can be used only if the ICG waveform has sufficient signal
quality and is without artifact.
The method of impedance cardiography (ICG) is based on a theoretical model of blood flow
