Therapy adjustment
First Claim
1. A method comprising:
- sensing a first value of a patient 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;
detecting a change from the first value of the patient parameter to a second value of the patient parameter;
determining a first rate of the change from the first value to the second value of the patient parameter;
identifying a second therapy parameter value based on the second value of the patient parameter;
determining a second rate based on the first rate of the change; and
adjusting the delivery of the therapy to the patient from the first therapy parameter value to the second therapy parameter value at the second rate.

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.
