Abstract: A system and method for non-invasive monitoring of cardiac activity in a human or animal is disclosed. A radiation source directs radiation through a patient site, and a detector detects radiation after passing through a patient tissue. A processor processes data derived from the detected radiation, determining pulse peaks and troughs and calculating area under a pulse peak to provide a real time cardiac output indicator. The radiation wavelength is on a haemoglobin spectral isosbestic point, not influenced by changes in SpO2 concentration. The processor performs numerical integration of pulse data between troughs, and wherein said integration is performed per pulse. Preferably, the processor monitors trends, thus providing very useful information and reducing need for calibration.
