1. What is Oral Potassium Replacement?

Oral potassium replacement is a method of correcting potassium deficiency using oral supplements. The conversion from IV to oral dosing follows an approximate 1:1.5 ratio, meaning oral doses are typically 1.5 times higher than IV doses to account for differences in bioavailability.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• IV Dose — Intravenous potassium dose in millimoles (mmol)
• 1.5 — Conversion factor accounting for bioavailability differences

Explanation: This conversion accounts for the reduced bioavailability of oral potassium compared to intravenous administration.

3. Importance of Potassium Replacement

Details: Proper potassium replacement is essential for maintaining normal cellular function, nerve transmission, and muscle contraction. Hypokalemia can lead to serious cardiac arrhythmias and muscle weakness.

4. Using the Calculator

Tips: Enter the IV potassium dose in mmol. The calculator will provide the equivalent oral dose. Always consult with a healthcare professional before administering potassium supplements.

5. Frequently Asked Questions (FAQ)

Q1: Why is the oral dose higher than the IV dose?
A: Oral potassium has reduced bioavailability compared to IV administration due to gastrointestinal absorption limitations.

Q2: Is this conversion accurate for all patients?
A: This is an approximate conversion. Individual patient factors may require adjustment based on clinical assessment.

Q3: When should IV potassium be used instead of oral?
A: IV potassium is typically reserved for severe hypokalemia or when oral administration is not possible due to gastrointestinal issues.

Q4: Are there risks with oral potassium supplementation?
A: Yes, excessive potassium can cause hyperkalemia, which is potentially life-threatening. Always monitor levels and follow medical guidance.

Q5: What forms of oral potassium are available?
A: Common forms include potassium chloride tablets, liquid solutions, and powder formulations that can be mixed with water.
