À propos de ce contenu audio
In this QuikCrit, we break down when calcium actually helps in hyperkalemia, and when it doesn’t.
Starting with a crashing patient and a wide QRS, we walk through the cardiac action potential, why hyperkalemia slows conduction, and how calcium stabilizes the myocardium without lowering potassium.
We cover:
- Why Vₘ follows potassium (Vₘ ≈ Eₖ)
- How calcium raises threshold potential and restores conduction
- ECG changes in hyperkalemia
- Calcium chloride vs gluconate
- The role of calcium in PEA arrest
- Why giving calcium blindly may not help, and may cause harm
Bottom line:
Calcium isn’t a routine arrest drug, it’s targeted therapy for hyperkalemia.
