Classification: CPC A  G | IPC A  G

Claim 8:
9. An apparatus, comprising:
at least one processor; and
a non-transitory computer readable medium communicatively coupled to the at least one processor, the non-transitory computer readable medium having stored thereon computer software comprising a set of instructions that, when executed by the at least one processor, causes the apparatus to:
monitor one or more ambient environmental conditions near or around a user or patient;
receive physiological data of the user or patient, the physiological data comprising photoplethysmograph (PPG) waveform data;
analyzing the PPG waveform data against a compensatory reserve index model of PPG waveform data representing a combination of a plurality of postures and motions of the user or patient;
determine at least one physiological state of the user or patient, based at least in part on the analysis of the PPG waveform data, wherein the at least one physiological state of the user or patient comprises a hydration state of the user or patient;
send the determined at least one physiological state of the user or patient to a user or patient device; and
output one or more display signals to a user or patient device for displaying the determined at least one physiological state of the user.
