A physiological parameter monitoring system and method is described. The system includes a plurality of sensors configured to obtain from a subject at least one observable voltage containing two or more signals. The system also includes a data manager and a data auxiliary device. The data manager is in communication with the plurality of sensors and is configured to assemble and format data obtained by the plurality of sensors. The data manager is configured to isolate one of the two or more signals. The method includes placing a plurality of sensors in communication with a subject, transmitting data from the plurality of sensors to a data manager, and isolating a desired voltage signal from the plurality of voltage signals.
