Epi Gets Pulses Back. But Then What?

You know the dose: 1 mg every 3–5 minutes. Congratulations—you’ve memorized the box. But do you actually know what epinephrine is doing after you push it? In this episode of The Ten Minute Medic, we dig into why epi doesn’t magically “restart the heart,” how alpha-mediated vasoconstriction and coronary perfusion pressure give the myocardium a fighting chance, why timing differs between shockable and nonshockable arrests, and why getting ROSC isn’t necessarily the same thing as saving a life. We’ll also tackle the uncomfortable evidence behind our favorite little 1-mg syringe. Because if your entire understanding of epinephrine is “the algorithm says give it,” we need to talk.
