1. What is the mL/kg/hr Rate?

The mL/kg/hr rate is a common measurement used in medical settings, particularly for calculating infusion rates of medications or fluids based on a patient's weight and over a specific time period.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( mL \) — Volume in milliliters
• \( kg \) — Patient's weight in kilograms
• \( hr \) — Time duration in hours

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

3. Importance of Rate Calculation

Details: Accurate rate calculation is crucial for safe medication administration, especially for weight-based medications where dosage needs to be precisely adjusted for each patient.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: When is mL/kg/hr used?
A: This rate is commonly used for pediatric medications, chemotherapy infusions, and critical care IV fluid administration.

Q2: How do I convert from mL/hr to mL/kg/hr?
A: Divide the mL/hr rate by the patient's weight in kg to get mL/kg/hr.

Q3: What are typical mL/kg/hr rates?
A: Maintenance IV fluids are often given at 1-2 mL/kg/hr for adults, but this varies based on clinical situation.

Q4: Does this work for all medications?
A: No, some medications have maximum absolute rates (mL/hr) regardless of weight.

Q5: How precise should the calculation be?
A: For most clinical purposes, rounding to 1-2 decimal places is sufficient.
