High Definition Impedance CardioGraphy (HD-ICG), for non-invasive cardiac output and fluid status monitoring


The ODM+ system already delivers true flow-based measurement of Stroke Volume and Cardiac Output through oesophageal Doppler and now includes non-invasive, easy-to-use, cost-effective HD-ICG. Both oesophageal Doppler and HD-ICG systems measure blood flow centrally to avoid some of the limitations associated with peripheral arterial pressure-based technologies.

HD-ICG is suitable for a wide range of clinical applications:

  • Awake surgery
  • Pre/Postoperative monitoring
  • Intensive Care
  • Emergency sugery
  • Ward

HD-ICG provides continuous, accurate and sensitive measurements of cardiac output and other haemodynamic parameters. The system is stabilised using HD-Z signal filter technology.

HD-ICG disposable electrodes are placed on the neck and chest. The electrodes transmit and detect electrical and impedance changes in the thorax which are then utilised to measure and calculate haemodynamic parameters, including:

  • Stroke Volume/Stroke Volume Index
  • Cardiac Output/Cardiac Index
  • Heart Rate
  • Contractility
  • Ventricular Ejection Time, corrected for heart rate (VETc)
