Epinephrine is given during cardiac arrest at what frequency?

Epinephrine is given during cardiac arrest at what frequency?

• A. Every 1 minute
• B. Every 2 minutes
• C. Every 3-5 minutes
• D. Only once

Answer: (C)

During CPR, epinephrine acts to raise coronary and cerebral perfusion pressures by causing vasoconstriction. Because its effect is not permanent, it’s given at regular intervals that fit the resuscitation cycle. The standard is to administer a 1 mg IV/IO dose every 3 to 5 minutes. This cadence provides ongoing vasopressor support during ongoing chest compressions and potential defibrillation attempts, without the risks that come with dosing more frequently. It’s not a one-time dose, and giving it more often than every 3 minutes hasn’t shown added benefit and may increase harmful effects.”
