17-2 Dash™ 3000/4000/5000 2000966-386D
Monitoring Impedance Cardiography (ICG)
Introduction
Overview
The monitor uses an ICG module to acquire impedance cardiography data. When the
ICG module is installed into the TRAM-RAC 2A module housing, the ICG parameter
window displays one primary ICG parameter and up to three secondary ICG
parameters. The display updates every two seconds.
The ICG parameter also displays a waveform. The ICG waveform is not
synchronized with any parameter. A message “DELAYED” displays with the
waveform due to an approximately four-second patient data delay.
Monitored Parameters
