Abstract
A tissue profile wellness monitor measures a physiological parameter, generates a tissue profile, defines limits and indicates when the tissue profile exceeds the defined limits. The physiological parameter is responsive to multiple wavelengths of optical radiation after attenuation by constituents of pulsatile blood flowing within a tissue site. The tissue profile is responsive to the physiological parameter. The limits are defined for at least a portion of the tissue profile.

2. A patient monitor comprising:
-
a front-end interface configured to receive, from a sensor comprising a light source that emits a plurality of wavelengths of light into a tissue site of a patient and a detector that detects the emitted light after attenuation by the tissue site, a signal indicative of the detected light at each of the plurality of wavelengths; and a processor configured to; normalize the signal, wherein the normalized signal is indicative of a tissue profile; and analyze the normalized signal that is indicative of the tissue profile at at least some of the plurality of wavelengths to determine a patient wellness. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A patient monitor comprising:
-
a front-end interface configured to receive, from a sensor comprising a light source that emits a plurality of wavelengths of light into a tissue site of a patient and a detector that detects the emitted light after attenuation by the tissue site, a signal indicative of the detected light at each of the plurality of wavelengths; and a processor configured to; determine, based on the signal, a relationship among light attenuation values associated with at least some of the plurality of wavelengths; and evaluate a shape of the determined relationship in relation to a predetermined limit to determine a patient wellness. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
