Patent Images
1. A patient monitoring system, comprising:
- a RFID tag configure to being associated with a patient and comprising an information element and a radio frequency tag antenna configured to transmit radio signals indicative of data stored in the information element; and
a portable patient monitor comprising (i) one or more sensors configured to output physiological data indicative of light attenuated by body tissue of the patient, (ii) a radio frequency antenna configured to receive signals from the RFID tag, and (iii) a monitor unit configured to communicate with the RFID tag through the radio frequency antenna of the monitor, and configured to communicate with the sensors to receive the physiological data and to process the data to determine one or more physiological characteristics of the patient.

Abstract
One aspect of the disclosure is to provide a patient monitoring system including a radio frequency identification (RFID) tag. The system comprises a patient monitor capable of communicating with the RFID tag. The RFID tag may advantageously store information useful in hospital environments, triage or disaster environments, home care environments, or the like. In some embodiments, the RFID tags may be provided as parts of wrist bands, dog tags, disposable sensor components, sensors or the like that are left with a patient.
