THERAPY ADJUSTMENT
First Claim
1. A method comprising:
- sensing a first value of a parameter of a patient;
delivering therapy to the patient according to a first therapy parameter value associated with the first value of the patient parameter in a data structure comprising a plurality of patient parameter values and associated therapy parameter values;
detecting a change from the first value of the patient parameter to a second value of the patient parameter;
identifying a third value of the patient parameter within the data structure that is closest to the second value of the patient parameter, wherein the third value of the patient parameter is associated with a second therapy parameter value within the data structure; and
determining an intermediate therapy parameter value that provides efficacious therapy to the patient when the second value of the patient parameter is observed by interpolating the therapy parameter between the first and second therapy parameter values.

Abstract
Systems and methods for adjusting a therapy delivered to a patient include detecting a value of at least one sensed patient parameter and adjusting a therapy parameter value to accommodate different patient parameter values. A data structure including a plurality of patient parameter values and associated therapy parameter values may be stored within a medical device or a programming device. Upon detecting a patient parameter value, an associated therapy parameter value from the data structure may be selected. If no therapy parameter value is associated with the detected patient parameter value, an intermediate therapy parameter value may be generated by interpolating between the most recently implemented therapy parameter value and a stored therapy parameter value. In some embodiments, the rate of shifting between parameters of two stored or interpolated therapy parameter values may be based on the rate of change of the patient parameter value over time.
