LiDCOplus is a hemodynamic monitor, providing continuous, reliable and accurate assessment of the hemodynamic status of critical care and surgery patients. This is achieved by running two proprietary algorithms: a continuous arterial waveform analysis system (PulseCO™) coupled to a single point lithium indicator dilution calibration system (LiDCO™).
Overview of the LiDCOplus Hemodynamic Monitor Technology
The advent of a reliable method for beat-by-beat derivation of hemodynamic parameters from the existing arterial pressure catheter and waveform provides surgeons, anesthesiologists and other intensivists a significantly improved hemodynamic monitoring option. The LiDCOplus Hemodynamic Monitor is designed to improve patient management. The LiDCOplus Hemodynamic Monitor requires calibration with the absolute value obtained from a single point cardiac output measurement once every eight hours.
The PulseCO™ Software
The PulseCO software provides continuous assessment of a patient's hemodynamic status, by analysing and processing the arterial pressure signal obtained from the primary blood pressure monitor.
The concept of using the blood pressure waveform to measure blood flow changes has been previously suggested by a number of investigators. Such methods provide cardiac output trend data following calibration by an independent, preferably an indicator dilution based, cardiac output measurement.
