CALCULATION DEVICE FOR METABOLIC CONTROL OF CRITICALLY ILL AND/OR DIABETIC PATIENTS
First Claim
1. A method of providing a blood glucose therapy for a critically ill patient, said method comprising the steps of:
- calculating a baseline nutritional feed requirement for said patient based on an algorithm that incorporates at least a weight of said patient;
determining a first body temperature of said patient;
determining a first blood glucose level of said patient;
determining at least a second body temperature of said patient after a preselected time period;
determining at least a second blood glucose level of said patient after a preselected time period; and
comparing said at least second blood glucose level to said first blood glucose level;
administering one of an amount of nutritional feed to said patient and an amount of insulin to said patient;
wherein said amount of nutritional feed administered to said patient is based on a first decrease in blood glucose level and a predetermined feed algorithm that incorporates said second blood glucose level and said patient'"'"'s baseline nutritional feed requirement; and
wherein said amount of insulin administered to said patient is based on a second decrease in blood glucose level that is less than said first decrease in blood glucose level and a predetermined insulin algorithm that incorporates said at least second blood glucose level and said patient'"'"'s weight.

Abstract
A method of providing blood glucose therapy for a critically ill patient includes calculating a baseline nutrition feed requirement based on an algorithm that incorporates at least one of age, gender, and body size of the patient: determining a first blood glucose level; determining a second blood glucose level after a preselected time interval: determining a first body temperature reading: comparing the blood glucose levels: and administering either nutrition or insulin. The amount of nutrition administered to the patient is based on a first change in blood glucose level, the current body temperature reading, and a predetermined feed algorithm based on the second blood glucose level as well as the baseline nutritional feed requirement. The amount of insulin administered is based on a second change in blood glucose level, body temperature, and a predetermined insulin algorithm that incorporates at least one of the patient'"'"'s body frame size, age, and gender.
