Maintaining glycemic control during exercise
First Claim
1. A computer-implemented method for modifying insulin basal rate delivery to adapt to a user'"'"'s exercise activity, comprising:
- receiving a first value corresponding to a first glucose concentration before an exercise activity of a user;
receiving a second value corresponding to a second glucose concentration after the exercise activity of the user;
determining a glucose concentration change based on a difference between the second value and the first value;
modifying a basal rate based on a comparison of the glucose concentration change with a predetermined threshold value;
advising the user to consume carbohydrates if the modified basal rate is insufficient to compensate for the exercise activity;
determining a recommended amount of carbohydrates wherein the modified basal rate is set to a minimum, and the recommended amount of carbohydrates is determined by calculating;
Carb=CIR*[(Basalmin*texercise)+(Δ
/IS*T))*texercise−
Basal*texercise]wherein;
Carb represents the recommended amount of carbohydrates,CIR represents the user'"'"'s carbohydrate to insulin ration,Basalmin represents the minimum basal rate,texercise represents an exercise parameter associated with the exercise activity,Δ
represents the glucose concentration change,IS represents the user'"'"'s insulin sensitivity,T represents a duration of the exercise activity, andBasal represents the user'"'"'s basal rate;
delivering insulin to the body of the user according to the modified basal rate; and
wherein at least one of receiving the first value, receiving the second value, determining, advising, and modifying is performed by one or more computer processors.

Abstract
Devices, apparatuses and methods for controlling blood-glucose levels during exercise are described. For example, an insulin infusion apparatus can include a control module to regulate a rate of therapeutic fluid release into a body of a patient based on a determined therapeutic fluid requirement profile, and a dispensing unit to release therapeutic fluid at the regulated rate. The methods and devices can be implemented by receiving a first value corresponding to a first glucose concentration before an exercise activity of a user; receiving a second value corresponding to a second glucose concentration after the exercise activity for the user; determining a glucose concentration change based on a difference between the second value and the first value; modifying a basal rate based on a comparison of the glucose concentration change with a predetermined threshold value; and, recording the modified basal rate in a computer-readable memory device.
