Electrolyte Management
Correction protocols for Potassium, Calcium, Magnesium, and Phosphorus.
Potassium Correction
Enter current serum K+ level to get specific recommendations.
Clinical Pearls
Expected Rise
Every 10 mEq of KCl raises serum K+ by approximately 0.1 mmol/L.
ECG Changes
- Peaked T waves (K 5.5-6.5)
- Prolonged PR, wide QRS (K 6.5-7.5)
- Sine wave (K > 7.5) - imminent arrest
Drug Interactions
ACE-I, ARBs, NSAIDs, Spironolactone increase K+ retention.
Always Check Mg!
Hypomagnesemia causes renal K+ wasting.
