Abstract
Determination of a physiological parameter value includes reception of several signals, each representing a respective one of several physiological parameters and including a pulsation associated with the parameter. A system detects a pulsation associated with a physiological parameter. The system includes an input device for receiving a plurality of different signals, each of the plurality of different signals indicating a pulsation in respective different physiological parameters. A signal processor detects and accumulates information from the plurality of different signals. The accumulated information including values of relative delay between the pulsation in the respective different parameters. A timing processor determines a timing of the pulsation in at least one of the different parameters based at least on the accumulated information. The physiological parameters include parameters associated with at least two of, non-invasive blood pressure, invasive blood pressure, heart beat, blood oxygen saturation level, respiration rate, an ECG and temperature.
