Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
Frequently asked questions
Defibrillation energy by weight: What does this calculator compute?
Calculates the energy for defibrillation (ERC 2025: 4 J/kg, escalation up to 8 J/kg; AHA 2025: 2 → 4 → ≥ 4 J/kg, at most 10 J/kg) and synchronized cardioversion (ERC: 1 → 2 → 4 J/kg; AHA: 0.5–1 → 2 J/kg) for body weight, limited to the adult dose (at most 200 J biphasic).
