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.
