Cardiac Output Monitor reveals pump performance of the heart. The board provides Cardiac Output signal in analog form which can be displayed on standard Oscilloscope. It will form front end module to Patient Monitoring systems useful for the monitoring of stroke volume and cardiac output in patients. It is based on the principle of electrical impedance plethysmography and is non-invasive in nature.
This method has been reported to be accurate in majority of subjects except those with intracardiac shunts or valvular regurgitation and at present is the only non-invasive method for continuous cardiac output monitoring.
