Abstract
A method for wirelessly monitoring physiological data of a patient includes emitting a timing signal from a wireless emitter, receiving a timing signal at a receiver in a wireless patient monitor, recording physiological data from the patient over time at the wireless patient monitor, wherein the time is defined according to the timing signal, and transmitting the physiological data over a wireless network of a healthcare facility. Thereafter, physiological data recorded from two or more wireless patient monitors may be aligned in time according to the timing signal to create an aligned physiological representation for the patient.
