Abstract
Methods, systems and devices are provided for reducing the amount of data, processing and/or power required to analyze hemodynamic signals such as photoplethysmography (PPG) signals, pressure signals, and impedance signals. Methods, systems and devices are also provided for reducing the amount of processing required to determine blood oxygen (O2) saturation levels.
