1. What is mL/kg/hr?

mL/kg/hr is a unit of measurement that expresses fluid administration rate relative to a patient's body weight and time. It's commonly used in medical settings to calculate intravenous fluid rates, especially for pediatric patients or when precise fluid management is required.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Total mL} \) — Total volume of fluid in milliliters
• \( \text{weight} \) — Patient's weight in kilograms
• \( \text{hours} \) — Time period in hours

Explanation: The formula calculates how many milliliters of fluid should be administered per kilogram of body weight per hour.

3. Importance of mL/kg/hr Calculation

Details: Accurate fluid rate calculation is crucial for maintaining proper hydration, especially in pediatric patients, critical care, and when administering medications that require precise dosing based on weight and time.

4. Using the Calculator

Tips: Enter the total fluid volume in mL, patient's weight in kg, and the time period in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: When is mL/kg/hr used?
A: Commonly used in pediatric fluid therapy, critical care, and when precise weight-based fluid administration is required.

Q2: What are typical mL/kg/hr rates?
A: Maintenance fluid rates vary by age and condition, but common ranges are 1.5-2 mL/kg/hr for adults and 3-4 mL/kg/hr for children.

Q3: How does this differ from mL/hr?
A: mL/kg/hr accounts for patient weight, making it more precise for individualized therapy, while mL/hr is an absolute rate.

Q4: Should this be used for all patients?
A: Not always. Some patients may require adjusted rates based on clinical condition, renal function, or other factors.

Q5: How accurate should the weight measurement be?
A: For precise calculations, use actual body weight measured recently. Estimates may lead to inaccurate dosing.
