DETECTION OF OXIMETRY SENSOR SITES BASED ON WAVEFORM CHARACTERISTICS
First Claim
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 critera associated with different physical locations on the patient'"'"'s body 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.
