PATHOLOGICAL STATE DETECTION USING DYNAMICALLY DETERMINED BODY INDEX RANGE VALUES
First Claim
1. A method for detecting a pathological body state of a patient, comprising:
- receiving a first body signal of the patient;
determining a first body index from said first body signal;
determining an activity level of said patient;
determining a non-pathological range for said first body index, based at least in part on said activity level;
comparing said first body index to said non-pathological range for said first body index;
detecting a pathological body state when said first body index is outside said non-pathological range.

Abstract
We report method of detecting a pathological body state of a patient, comprising receiving a body signal of the patient; determining a body index from said body signal; determining an activity level of said patient; determining a value range for said body index for said patient, based at least in part on said activity level; comparing said body index to said value range; and detecting a pathological state when said body index is outside said value range. We also report a medical device system configured to implement the method. We also report a non-transitory computer readable program storage unit encoded with instructions that, when executed by a computer, perform the method.

14. A method of determining a pathological state in a patient, comprising:
-
receiving data relating to an activity level of said patient; determining an activity level of the patient based on said data relating to an activity level; receiving at least one body signal of the patient; determining at least a first body index based on said at least one body signal; dynamically determining a reference value range for said at least a first body index based on said activity level; determining that the patient is in one of a non-pathological state and a pathological state, wherein said patient is determined to be in a non-pathological state if the at least a first body index is within said reference value range for said activity level, and said patient is determined to be in a pathological state if the at least a first body index is outside said reference value range; and taking at least one further action based on determining that the patient is in a pathological state, wherein said further action is selected from treating said pathological state, issuing a warning to the patient or a caregiver regarding said pathological state, logging the occurrence of said pathological state, logging the response to a therapy, or logging a severity of said pathological state. - View Dependent Claims (15, 16, 17, 18)

19. A medical device system, comprising:
-
at least one kinetic sensor, each said sensor configured to collect at least one kinetic signal from a patient; an activity level module configured to determine an activity level of said patient, based at least in part on said at least one kinetic signal; at least one sensor configured to sense a body signal; a body index determination module configured to determine at least a first body index based on said sensed body signal; a body index range module, configured to determine a non-pathological body index range for said at least a first body index, based at least in part on said activity level; and a pathological state determination module, configured to determine that the patient is in one of a non-pathological state and a pathological state, wherein said patient is determined to be in a non-pathological state if the at least a first body index is within said non-pathological body index range for said at least a first body index, and said patient is determined to be in a pathological state if the at least a first body index is outside said non-pathological body index range for said at least a first body index. - View Dependent Claims (20, 21, 22)
