Insulin Management and Strategies-Insulin Bolus Calculations

Insulin Bolus Calculations

Pdf Summary

The Insulin Bolus Calculator for Carbohydrate Counting is designed to assist individuals in managing their insulin doses based on carbohydrate intake and blood glucose levels. The process involves several steps:

1. <strong>Calculate Insulin-to-Carbohydrate (I:C) Ratio</strong>: This ratio is determined using the Rule of 500. It indicates how many grams of carbohydrates are covered by one unit of insulin. For example, a ratio of 1:10 means one unit of insulin covers 10 grams of carbohydrates.

2. <strong>Calculate Insulin Correction/Sensitivity Factor (ICF/ISF)</strong>: This is determined using the Rules of 1500, 1700, or 1800. The ICF/ISF measures how many points the blood glucose level will drop per unit of insulin. The rule applied depends on individual patient characteristics, such as insulin sensitivity or the type of insulin used.

   - <strong>1800 Rule</strong>: Suitable for insulin-sensitive individuals using rapid-acting insulin.
   - <strong>1700 Rule</strong>: A commonly used average, especially for insulin pump users.
   - <strong>1500 Rule</strong>: For those using short-acting insulin or less insulin-sensitive.

3. <strong>Calculate Carbohydrate Bolus</strong>: Determine the insulin dose based on carbohydrate intake.

4. <strong>Calculate Blood Glucose Correction Bolus</strong>: Establish a glucose goal, typically recommended by the ADA as preprandial plasma glucose of 80-130 mg/dL, adjusted based on patient-specific factors.

5. <strong>Calculate Total Insulin Bolus Dose</strong>: This involves summing the carbohydrate bolus and glucose correction bolus. Appropriate rounding rules ensure doses are manageable:
   - For unit calculations, 0.1-0.3 rounds down, 0.4-0.7 to the nearest half, and 0.8-0.9 rounds up.
   - For whole unit calculations, 0.1-0.4 rounds down, and 0.5-0.9 rounds up.

This comprehensive approach allows for precise insulin management tailored to individual patient needs.
