Medical monitoring device for harmonizing physiological measurements

A method for determining a physiological parameter of an individual, the method comprising:

• receiving, from a sensor apparatus comprising a non-invasive plethysmography sensor and a Raman spectrometer, first data associated with the non-invasive plethysmography sensor, wherein the first data is responsive to light attenuated by a particular region of tissue of an individual;
• receiving, from the sensor apparatus, second data associated with the Raman spectrometer, wherein the second data corresponds to the Raman spectra of the particular region of the tissue;
• filtering an effect of absorbance on the Raman spectra based at least in part on the first data;
• estimating an analyte level based at least in part on the filtered Raman spectra;
• outputting a visual or audible indication of the analyte level;
• and
• modifying, based at least in part on the analyte level, a treatment of the individual performed by at least one of a drug administration device, a ventilator, a fluid IV, a fan, or a thermostat.

A system for determining a physiological parameter of an individual, the system comprising:

• a sensor apparatus comprising:
• a non-invasive plethysmography sensor configured to generate first data, wherein the first data is responsive to light attenuated by a particular region of tissue of an individual,
• a second sensor configured to generate second data, wherein the second data corresponds to spectra of the particular region of the tissue, and
• a housing configured to secure the non-invasive plethysmography sensor and the second sensor;
• and
• one or more processors configured to:
• receive the first data associated with the non-invasive plethysmography sensor,
• receive the second data associated with the second sensor,
• filter the spectra based at least in part on the first data;
• estimate an analyte level based at least in part on the filtered spectra;
• and
• output the estimate to a display or an audible output device.
