Systems And Methods For Autonomic Nervous System Monitoring
First Claim
1. A method for determining physiological information about a subject, the method comprising:
- receiving a physiological signal affected by a patient'"'"'s respiration, wherein at least one characteristic of the patient'"'"'s respiration is known;
transforming the physiological signal using processing equipment into a transformed signal; and
determining using the processing equipment, information about the patient'"'"'s autonomic nervous system based at least in part on the transformed signal and the at least one characteristic of the patient'"'"'s respiration.

Abstract
Methods and systems are disclosed for determining physiological information about a patient'"'"'s autonomic nervous system based on at least one physiological signal measured from the patient and at least one known characteristic of a patient'"'"'s respiration. Respiration protocol may be provided to guide characteristics of the patient'"'"'s respiration. The physiological signal measured from the patient may be transformed using a wavelet transform to create a transformed signal, and a scalogram may be generated based at least in part on the transformed signal. A metric that may indicate information about the patient'"'"'s autonomic nervous system may be determined from the scalogram and the known characteristic of the patient'"'"'s respiration.
