How often should Epinephrine be given during cardiac arrest?

Explanation:
During cardiac arrest, epinephrine is used to boost blood flow to the heart and brain by increasing perfusion pressure during CPR. To keep that effect going, the medication is given in repeating doses at roughly CPR-cycle intervals. Guidelines support administering epinephrine every 3-5 minutes, with the dose typically given IV/IO each time. Among the options, every five minutes aligns with this standard practice, ensuring repeated dosing as long as the arrest continues. Giving it more frequently (every minute or every 2 minutes) isn’t in line with the guideline window, and giving it only once would not sustain its benefit during ongoing CPR.
