Abstract
A non-invasive patient hydration monitoring system, device, and method are disclosed. The invented device utilizes a non-invasive photo-plethysmographic (PPG) finger- or toe-probe with an infrared transceiver to measure blood perfusion or circulation in an extremity. Such perfusion data is processed using correlation techniques into patient hydration data by a microprocessor and software application that preferably resides in a cell phone or similar portable hardware/firmware/software platform. Individual and successive patients can be quickly screened, baselined, diagnosed, and reported to identify individuals with dehydration conditions that are indicators of more important health issues such as disease and contagion.
