How do you calculate corrected insulin?

The amount blood glucose is lowered by the injection of 1 unit of insulin is called the insulin sensitivity factor (also known as the correction factor) , and is calculated by dividing the constant 1700 by the Total Daily Dose (TDD) of rapid acting insulin or dividing the constant 1500 by the Total Daily Dose of …

How do you calculate ISF?

The 100 rule (1800 rule for mg/dl) has been used to find the insulin sensitivity factor (ISF), that is, how many mmol/l (or mg/dl) 1 unit of insulin lowers the blood glucose level. ISF equals 100 divided by TDD (1800 divided by TDD for mg/dl).

What is the 500 rule for insulin?

Use the 500 Rule to estimate insulin-to-carb ratio: 500/TDD = number of carb grams covered by a unit of insulin. Example: 500/50=10; 1unit of insulin will cover about 10 grams of carbohydrate.

How is insulin factor calculated?

For example, if you take 30 units of regular insulin daily, divide 1500 by 30. This equals 50. This means your insulin sensitivity factor is 1:50, or that one unit of regular insulin will lower your blood sugar by about 50 mg/dL.

How do you calculate bolus correction?

Example:

  1. 220 (actual blood glucose) – 120 (target blood glucose) = 100 (amount to correct), so.
  2. 100 (amount to correct) ÷ 50 (correction factor) = 2 (correction bolus), so.
  3. Give 2 units of rapid-acting insulin to bring blood glucose back into target range.

How is mealtime insulin calculated?

To calculate your mealtime insulin, you need to take the number of carbohydrate grams in your meal and divide it by the grams of carbohydrates covered by one unit of insulin.

What is insulin ISF?

Your ISF can also be known as your “correction ratio” or “correction factor”. Insulin sensitivity factors. Your ISF is the number of mmol/L that one unit of insulin will lower your blood glucose level by. For example, a ratio of 1:2 means that one unit of insulin will drop your blood glucose level by 2mmol/L.

What is the 450 rule for insulin?

Alternatively, the insulin-to-carbohydrate ratio (ICR) may be determined by the “450 rule.” To determine the ICR, divide 450 by the child’s total daily dose of insulin (TDD). For example, for a child with a TDD of 36 units, the ICR would be 450/36 = 12.5, or 1 unit per 12 g of carbohydrate.

What is the rule of 450?

The carbohydrate-to-insulin ratio (CIR) is the number of grams of carbohydrate that are covered by 1 unit of insulin. The CIR is calculated by dividing the constant 450 by the Total Daily Dose (TDD). The CIR may be different for different meals of the day.

What is the 100 rule in diabetes?

The 100 rule is starting with 100, and dividing the average amount of insulin given over the last five days. For example if the average daily dose of insulin is 50. Calculation is 100 divide 50. You can see if your sensitivity is correct by looking at your record book.

What is correction factor?

A correction factor is a factor multiplied with the result of an equation to correct for a known amount of systemic error. … This process of evaluating factors that lead to uncertainty in measurement results is known as uncertainty evaluation or error analysis.

When do you give insulin correction?

When to give a correction dose:

You can give a correction dose whenever you find a blood glucose level above target before a meal and above 9mmol/L 2hours after a meal. Always check your blood glucose level 2hours after taking a correction dose.

How do you calculate basal bolus insulin?

If insulin required in hospital or patient requires titration of BBIT: Total Basal = TDD x 0.5 glargine (Lantus®/Basaglar®) dosed once daily OR detemir (Levemir®) or HumuLIN® N dosed twice daily breakfast and bedtime.

How do you pre bolus insulin?

The Secret Behind Pre-Bolus Timing

A pre-bolus is taking your meal bolus “xx” minutes before eating to better match your insulin’s peak action time with your meal’s digestion.
