1. A method for determining a patient'"'"'s adherence to a mix of medications in a medication regimen, said method comprising:

  • providing patient operable instrumentation comprising;

    a plurality of physiological monitoring devices configured to obtain a plurality of different types of actual patient pulse wave measurements comprising electrode-based time varying electrocardiograph readings, and time varying blood oxygen saturation levels, and time varying blood pressure measurements;

    at least one processor configured to control the plurality of physiological monitoring devices and memory;

    wherein said patient operable instrumentation and said physiological monitoring devices are a unitized, common processor controlled, system including;

    wherein said time varying blood pressure measurement types are oscillometric cuff type blood pressure measurements;

    obtaining a plurality of medication impact parameters, each individual medication impact parameter providing information on how a specific medication alters a specific type of pulse wave measurements, the plurality of medication impact parameters including medication impact parameters for each medication in the mix;

    obtaining a plurality of patient reference information, each individual patient reference information providing information on a specific type of patient baseline pulse wave measurement in an absence of patient medication;

    wherein said plurality of medication impact parameters and plurality of patient reference information further provide information corresponding to all of said different types of actual patient pulse wave measurements;

    obtaining dosing schedule information for the mix of medications of the medication regimen;

    storing the plurality of medication impact parameters, the plurality of patient reference information, and the dosing schedule information in said memory;

    obtaining said plurality of different types of actual patient pulse wave measurements with the patient operable instrumentation;

    analyzing, using said at least one processor, said plurality of different types of actual patient pulse wave measurements;

    calculating, using said at least one processor, expected patient pulse wave measurements, corresponding to all of the different types of actual patient pulse wave measurements, based on the mix of medications, said dosing schedule information and said plurality of patient reference information and said plurality of medication impact parameters;

    identifying which one or more medications from the mix of medications in the regimen was not taken by the patient, based on determining, using said at least one processor, which of said plurality of different types of actual patient pulse wave measurements are inconsistent with said expected patient pulse wave measurements; and

    issuing an alarm reporting the one or more medications not taken by the patient.
