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 location of the sensor as either corresponding to a forehead or a digit based on a comparison of the identifying characteristic with at least one defined criterion associated with the digit and at least one defined criterion associate with the forehead using the processor.

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.
