Methodology · worked example, guidelines & full notes
IV calcium stabilizes the myocardium within minutes but does not lower potassium, so it is paired with shifting and removal therapies. (original synthesis · not guideline verbatim)
When to use
Use at the bedside to decide whether calcium, insulin/glucose, and removal therapy are needed and to choose dialysis versus binders by renal function.
How it works
Emergency = [pending update] or hyperkalemic ECG changes. (1) Calcium gluconate stabilizes membrane; (2) insulin + glucose, salbutamol, ± bicarbonate shift; (3) loop diuretic/binders/dialysis remove (dialysis first-line in renal failure).
Key points
- IV calcium stabilizes the myocardium within minutes but does not lower potassium, so it is paired with shifting and removal therapies. (original synthesis · not guideline verbatim)
- Pseudohyperkalemia (hemolysis, tourniquet, extreme cell counts) is excluded before aggressive treatment.
- Potassium-raising drugs are stopped with serial rechecks.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Serum potassium | 6.8 mmol/L |
|---|---|
| Hyperkalemic ECG changes (peaked T waves/loss of P waves/widened QRS, etc.) | Present |
| Renal function | Normal/adequate |
→DeterminationHyperkalemic emergency (severe)
- (1) Membrane stabilization：Immediate IV calcium to stabilize the myocardial membrane: 10% calcium gluconate slow push over 2–3 min (preferred over calcium chloride; repeat if no improvement in 5–10 min). Stabilizes only, does not lower potassium
- (2) Intracellular shift：Shift potassium intracellularly: regular insulin + glucose (50% glucose, monitor for hypoglycemia); nebulized salbutamol; add sodium bicarbonate if metabolic acidosis is present
- (3) Potassium removal：Remove body potassium: loop diuretic (furosemide) ± normal saline (if volume allows); potassium binders (sodium zirconium cyclosilicate/patiromer/sodium polystyrene sulfonate, start at K < 5.5 to prevent recurrence); consider dialysis for severe/refractory cases

FAQ
Frequently asked questions
- What are the limits and cautions when using Emergency Management of Hyperkalemia?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Emergency Management of Hyperkalemia upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Emergency Management of Hyperkalemia calculated in practice? Can you show a worked example?
- Inputs: Serum potassium 6.8 mmol/L, Hyperkalemic ECG changes (peaked T waves/loss of P waves/widened QRS, etc.) Present, Renal function Normal/adequate → Result: Determination Hyperkalemic emergency (severe)（(1) Membrane stabilization: Immediate IV calcium to stabilize the myocardial membrane: 10% calcium gluconate slow push over 2–3 min (preferred over calcium chloride; repeat if no improvement in 5–10 min).
