Wellness analysis system
A wellness analyzer is in communications with sensors that generate real-time physiological data from a patient. The wellness analyzer is also in communications with databases that provide non-real-time information relevant to a medical-related assessment of the patient. In a diagnostic mode, a monitor layer inputs the sensor data and adjunct layers input the database information. Adjunct layer logic blocks process the database information so as to output supplemental information to the monitor. Monitor logic blocks process the sensor data and the supplemental information so as to generate a wellness output. In a simulation mode, a simulator generates at least one parameter and the monitor generates a predictive wellness output accordingly.
