Glucose Infusion Rate Calculator

Formula

To calculate the Glucose Infusion Rate (GIR):

\[ GIR = \frac{BG - \text{Target}}{CF} \]

Where:

\(GIR\) is the Glucose Infusion Rate
\(BG\) is the Blood Glucose level in mg/dL
Target is the desired Blood Glucose level in mg/dL
\(CF\) is the Correction Factor

What is a Glucose Infusion Rate?

The Glucose Infusion Rate (GIR) is a medical term that refers to the rate at which glucose is administered intravenously to a patient. This is often used in critical care settings or during certain medical tests to either provide the body with necessary glucose or to measure the body’s insulin response. The rate is typically measured in milligrams per kilogram of body weight per minute (mg/kg/min).

Example Calculation 1

Let's assume the following values:

Blood Glucose Level (\(BG\)) = 180 mg/dL
Target Blood Glucose Level = 100 mg/dL
Correction Factor (\(CF\)) = 50

Using the formula:

\[ GIR = \frac{180 - 100}{50} = \frac{80}{50} = 1.60 \text{ mg/kg/min} \]

The Glucose Infusion Rate is 1.60 mg/kg/min.

Example Calculation 2

Let's assume the following values:

Blood Glucose Level (\(BG\)) = 250 mg/dL
Target Blood Glucose Level = 120 mg/dL
Correction Factor (\(CF\)) = 40

Using the formula:

\[ GIR = \frac{250 - 120}{40} = \frac{130}{40} = 3.25 \text{ mg/kg/min} \]

The Glucose Infusion Rate is 3.25 mg/kg/min.
