1. A method for assigning a physiologic sensor to a patient, comprising:
- monitoring a patient with a plethysmograph sensor detecting a plethysmograph signal from the patient;
monitoring the patient with an electrode sensor detecting an electrical signal from the patient;
receiving both the plethysmograph signal and the electrical signal at a remote monitor;
detecting, at the remote monitor, a sequence of heart beats in both the plethysmograph signal and the electrical signal;
matching, at the remote monitor, a sequence of the detected heart beats in the plethysmograph signal with a sequence of the detected heart beats in the electrical signal; and
assigning, at the remote monitor, both sensors to the same patient based on the matching features.

Abstract
A method for associating physiological sensors to patients includes acquiring associated physiological data from a first physiological sensor associated with an identified patient. The method also includes acquiring unassociated physiological data from a second physiological sensor associated with an unidentified patient. The method further includes comparing a parameter in the unassociated physiological data to a common or correlated parameter in the associated physiological data to determine if the second physiological sensor is associated with the identified patient.

13. A method for identifying a new wireless sensor, comprising:
-
receiving, at a patient monitor, physiologic data from a plurality of sensors each respectively monitoring a unique patient; receiving, at the patient monitor, new physiologic data from a new sensor not yet assigned to a patient; extracting a portion of the new physiologic data over a time duration and searching for a matching portion in the physiologic data from the plurality of sensors over the same time duration; identifying a match with a first sensor of the plurality of sensors; assigning the new sensor to the unique patient monitored by the first sensor; and displaying incoming physiologic data from the new sensor together with incoming physiologic data from the first sensor. - View Dependent Claims (14, 15, 16)

17. A system, comprising:
-
wireless communication circuitry configured to receive a first input signal from a first physiological sensor and a second input signal from a second physiological sensor; a memory storing identification data for a patient and association data associating the first physiological sensor and the second physiological sensor with the identification data; and a processor configured to; receive the first input signal from the first physiological sensor associated with the patient; compare a common feature in the first input signal from the first physiological sensor and in the second input signal from the second physiological sensor to determine if the second physiological sensor should be associated with the patient; and generate an error message when the first physiological signal and the second physiological signal should not be associated with the patient based on the common feature. - View Dependent Claims (18, 19, 20)
