1 mg Epinephrine, IO

Epinephrine is the first medication given in VF/VT arrests as well as for PEA/Asystole arrests. Atropine is only given in symptomatic bradycardias; amiodarone is given to correct refractory VF/VT; and adenosine is used to chemically cardiovert supraventricular tachycardias (SVTs).
