1. A method for detecting sensor placement, comprising:
- receiving a signal corresponding to absorption of at least one wavelength of light by a patient'"'"'s tissue;
generating a plethysmographic waveform from the signal;
determining an identifying characteristic of the plethysmographic waveform using a processor; and
determining a physical location of the sensor on the patient'"'"'s body based on a comparison of the identifying characteristic with defined criteria associated with different physical locations on the patient'"'"'s body using the processor, wherein determining the physical location of the sensor comprises determining whether the physical location of the sensor is a location on an extremity of the patient'"'"'s body or a location other than an extremity of the patient'"'"'s body.

Abstract
In accordance with an embodiment of the present technique, there is provided methods and systems for detecting the location of a sensor and determining calibration algorithms and/or coefficients for calculation of physiological parameters based on the detected location. An exemplary embodiment includes receiving a signal corresponding to absorption of at least one wavelength of light by a patient'"'"'s tissue, generating a plethysmographic waveform from the signal, determining an identifying characteristic of the plethysmographic waveform, and determining a location of the sensor based on a comparison of the identifying characteristic with at least one defined criterion.

12. A system for detecting sensor placement, comprising:
-
a sensor having a detector configured to detect the light; and a monitor configured to generate a plethysmographic waveform from the detected light, determine an identifying characteristic of the plethysmographic waveform, and determine a physical location of the sensor on a patient'"'"'s body based on a comparison of the identifying characteristic with defined criteria associated with different physical locations on the patient'"'"'s body, wherein the physical location of the sensor on a patient'"'"'s body is selected from the group consisting of a location on an extremity of the patient'"'"'s body and a location other than an extremity of the patient'"'"'s body. - View Dependent Claims (13, 14, 15, 16)
