ACLS Circular Algorithm – Memorize It
ACLS · Adult Cardiac Arrest Circular Algorithm

Keep the rhythm going.

Three quick drills to lock in the loop: the cycle sequence, the drug & energy doses, and the reversible Hs & Ts.

Put the 2-minute cycle in order

Drag the cards (or use the arrow buttons on mobile) into the order the algorithm runs every cycle, then check your work.

    Doses, energy, and timing

    Question 1 of 11

    Flip every reversible cause

    Click a card to reveal it. Try naming it out loud before you flip – the goal is all 11 without peeking.
