1. A method of communicating information from a patient monitoring device, comprising:
encoding information comprising non-physiological information according to a transmission scheme of a pulse oximeter;
emitting, from the pulse oximeter, a light signal with the encoded information according to the transmission scheme, wherein the light signal is emitted in a field of view of a video camera;
receiving, from the video camera, a video signal comprising the light signal; and
decoding, using a processor, the encoded information of the light signal.
