Medical monitoring device for harmonizing physiological measurements

A method for determining a physiological parameter by harmonizing data between two or more different types of non-invasive physiological sensors interrogating a shared tissue volume, the method comprising:

• receiving a first signal from a plethysmography sensor configured to interrogate a shared tissue volume and generate the first signal, wherein the first signal is indicative of first physiological data associated with the shared tissue volume;
• receiving a second signal from a bioimpedance sensor, wherein the second signal is indicative of second physiological data associated with the shared tissue volume;
• determining a physiological parameter based at least in part on the first and second signals;
• and
• outputting a visual or audible indication of the physiological parameter.

A physiological monitoring system configured to determine a physiological parameter by harmonizing data between two or more different types of non-invasive physiological sensors interrogating a shared volume of tissue, the physiological monitoring system comprising:

• a plurality of sensors configured to interrogate a shared volume of tissue of a patient, wherein each of the plurality of sensors is configured to generate a sensor signal associated with physiological data of the shared volume of tissue, wherein the plurality of sensors comprises a plethysmography sensor and a bioimpedance sensor;
• and
• a processor in communication with each of the plurality of sensors and configured to:
• receive the plurality of sensor signals,
• determine a physiological parameter associated with the shared volume of tissue based at least in part on the plurality of sensor signals, and
• output a visual or audible indication of the physiological parameter.
