How is ISF calculated in diabetes?

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).

How do you calculate correction factor?

Subtract the target blood sugar from the current sugar to calculate the gap. Then divide by the Correction (sensitivity) Factor to calculate the correction dose.

What is the sensitivity factor on an insulin pump?

Insulin sensitivity factor, or ISF, refers to how much or how many points (mg/dl) the blood sugar will drop in response to one unit of insulin. It is also known as a high blood sugar correction, and is set as one unit of insulin to lower a specific amount of glucose (in mg/dl).

How do I calculate how much insulin I need?

Divide the total carbohydrates by the insulin to carbohydrate ratio. The result is the amount of insulin units needed. Visit choa.org/diabetes for additional copies. Add the number of units needed for food to the number of units needed to correct blood sugar to get your total dose of insulin (Humalog/Novolog/Apidra).

How much does 1 unit of insulin bring down blood sugar?

One unit of insulin should cause your blood sugar level to drop 30 to 50 mg per dL, but you may need more insulin to get the same effect.

How do I know my insulin sensitivity?

How to test for insulin sensitivity factor

1. Check and record their blood sugar levels.
2. Take a correction dose of insulin, based on their current sensitivity factor.
3. Retest their blood sugar levels 2 and 3 hours after taking the insulin dose.

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 the calibration factor?

Definitions. Calibration Factor: A measure of the. chromatographic. response of a target analyte relative to the mass injected.

What is FT correction factor?

A ‘ft correction factor’ is defined as a ratio of the true mean temperature difference to the log-mean temperature difference (see Eq(2)). The ‘ft correction factor’ value must be greater than 0.75 for a heat exchanger to be feasible.

What is the 500 rule in diabetes?

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 do I adjust my insulin sensitivity?

You’ll need to divide the number of mg/dL you want to lower, which is 75, by the number from your insulin sensitivity factor calculation, which is 60. The answer of 1.25 tells you that you need to take 1.25 units of short-acting insulin to lower your blood sugar by 75 mg/dL.

What is the difference between insulin sensitivity and insulin resistance?

Insulin resistance and insulin sensitivity are two sides of the same coin. If you have insulin resistance, you have low insulin sensitivity. Conversely, if you are sensitive to insulin, you have low insulin resistance. While insulin resistance is harmful to your health, insulin sensitivity is beneficial.

How much insulin do I need Type 2 diabetics take?

Eventually, many people with Type 2 diabetes will require 1–2 units of insulin for every kilogram of body weight; that is, an 80-kilogram (175-pound) person will require at least 80 units of insulin each day. To start, however, your doctor may begin by prescribing 0.15 units of insulin per kilogram.

What is a typical sliding scale for insulin?

70-139 mg/dL – 0 units 140-180 mg/dL – 3 units subcut 181-240 mg/dL – 4 units subcut 241-300 mg/dL – 6 units subcut 301-350 mg/dL – 8 units subcut 351-400 mg/dL – 10 units subcut If blood glucose is greater than 400 mg/dL, administer 12 units subcut, notify provider, and repeat POC blood sugar check in 1 hour.

Uses: To improve glycemic control in patients with diabetes mellitus; U-500 insulin is for use in patients requiring more than 200 units of insulin per day.
