Epinephrine has been the standard vasopressor for use during cardiac arrest since the inception of modern CPR. The effectiveness of epinephrine is due to its ability to increase myocardial oxygen supply by improving coronary blood flow and pressure through peripheral vasoconstriction. Myocardial stimulation through beta-adrenergic receptors is unimportant for resuscitation. Pure alpha-adrenergic agents have been found to have similar success to epinephrine but no better. When used for initial therapy for cardiac arrest, higher doses of epinephrine have not been found to promote better survival than the standard 0.015 mg/kg dose.
