1. What is IVIG Infusion Rate?

The IVIG (Intravenous Immunoglobulin) infusion rate determines how quickly the medication should be administered. The rate is calculated by dividing the total volume to be infused by the desired infusion time.

2. How Does the Calculator Work?

The calculator uses the basic infusion rate equation:

Where:

• Volume — Total IVIG volume to be infused (mL)
• Time — Desired infusion duration (hours)

Explanation: This simple calculation helps determine the appropriate pump setting for IVIG administration.

3. Importance of Correct Infusion Rate

Details: Proper infusion rates are crucial for patient safety. Too rapid infusion can cause adverse reactions, while too slow infusion may delay treatment.

4. Using the Calculator

Tips: Enter the total volume in mL and the desired infusion time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical IVIG infusion rates?
A: Rates vary based on protocol and patient tolerance, often starting at 0.5-1 mg/kg/hr and gradually increasing.

Q2: Why is gradual rate increase important?
A: To minimize infusion reactions like headaches, fever, or hypotension that can occur with rapid administration.

Q3: How does concentration affect the rate?
A: Higher concentrations may require slower rates. Always follow manufacturer guidelines for specific products.

Q4: When should rate adjustments be made?
A: For patients with renal impairment, cardiovascular disease, or history of adverse reactions to IVIG.

Q5: Are there maximum recommended rates?
A: Yes, typically 8-10 mg/kg/hr for most products, but always consult specific product guidelines.
