Epinephrine (mg)
0.2
How to Use This Calculator
- Enter Patient Weight (kg) — use a Broselow tape measurement for unconscious patients.
- Enter Patient Age (years) to cross-check weight-based dosing.
- Review all drug doses: Epinephrine, Atropine, Amiodarone, Dextrose, and Adenosine.
- Check Defibrillation Initial Dose (2 J/kg) and Subsequent Dose (4 J/kg).
- Confirm Fluid Bolus (20 mL/kg isotonic saline) and draw up all medications before the resuscitation begins.
How the result changes with Patient Weight (kg)
| Patient Weight (kg) | Epinephrine (mg) |
|---|---|
| 10 | 0.1 |
| 35 | 0.35 |
| 65 | 0.65 |
| 90 | 0.9 |
What each input means
- Patient Weight (kg)
- Child's weight in kg. Use Broselow tape if weight unknown.
- Patient Age (years)
- Age in years. Affects atropine max dose and dextrose concentration.
What each result means
- Epinephrine (mg)
- 0.01 mg/kg IV/IO (1:10,000), max 1 mg.
- Epinephrine Volume (mL of 1:10,000)
- Volume to draw up from 1:10,000 concentration (0.1 mg/mL).
- Atropine (mg)
- 0.02 mg/kg IV, min 0.1 mg, max 0.5 mg (child) / 1.0 mg (adolescent).
- Amiodarone (mg)
- 5 mg/kg IV/IO, max 300 mg. For refractory VF/pVT.
- Defibrillation — Initial (J)
- 2 J/kg for first shock.
- Defibrillation — Subsequent (J)
- 4 J/kg for subsequent shocks.
- Fluid Bolus (mL)
- 20 mL/kg NS or LR. Reassess after each bolus.
- Adenosine — 1st Dose (mg)
- 0.1 mg/kg rapid IV push, max 6 mg.
- Adenosine — 2nd Dose (mg)
- 0.2 mg/kg rapid IV push, max 12 mg.
- Dextrose Volume (mL)
- D10W 5 mL/kg (infant) or D25W 2 mL/kg (child).
