Emergency

CPR dosing calculator

Weight-based doses for cardiopulmonary arrest per the 2024 RECOVER CPR guidelines. Enter patient weight to generate a patient-specific dose sheet.

For use during active CPR only. Confirm drug concentrations on every vial. Doses are IV/IO unless otherwise noted.

Quick reference

BLS cycle: 30 compressions : 2 breaths (1-rescuer) or 30:2 / continuous with async ventilation (2-rescuer). Rate 100–120/min, depth ⅓ chest.

Epinephrine: every 3–5 min after first dose.

Check rhythm every 2 min. Minimize interruptions.

CPR algorithm overview

The RECOVER guidelines follow a BLS-first approach. Establish IV/IO access as early as possible but do not interrupt compressions to do so.

Begin chest compressions immediately. Rate 100–120/min.
Establish airway, intubate if possible; bag-mask if not.
Attach ECG as soon as available, identify rhythm.
Shockable (VF/pVT): defibrillate → resume CPR immediately → recheck in 2 min.
Non-shockable (PEA/asystole): epinephrine IV/IO every 3–5 min; identify and treat reversible causes (4 Hs & 4 Ts).
Consider vasopressin as alternative or adjunct to epinephrine.
Atropine for PEA/asystole, rapid bolus.
Anti-arrhythmics (amiodarone or lidocaine) for refractory VF/pVT after 2nd shock.
Reversal agents if opioid, benzo, or alpha-2 sedation may be contributing.

Always verify drug concentrations against the vial in front of you. Stock concentrations vary by supplier and formulary.
