Abstract

Systems, methods, and devices for obtaining physiological measurements of a patient using an adaptive body network are provided. In one example, a wireless medical sensor may include physiological sensor circuitry, wireless transceiver circuitry, and control circuitry. The physiological sensor circuitry may be capable of obtaining a physiological measurement of a patient. The wireless transceiver circuitry may be capable of joining a wireless web that includes at least one other wireless medical sensor, through which the wireless transceiver circuitry may communicate the physiological measurement to an external device. The control circuitry may be capable of determining a data update rate at which to operate the physiological sensor or the wireless transceiver circuitry, or a combination thereof, based at least in part on a status of the patient.
