Abstract

A system includes a sensor configured to sense physiological information from a subject, and a signal processor configured to process signals from the sensor into a serial data stream of physiological information and sensor performance information. An electronic device having a display is configured to receive the serial data stream and display the physiological information simultaneously with the sensor performance information via the display.
