Are you struggling to remember ACLS algorithm? You’re not alone. With so many steps and decisions involved, it’s easy to feel overwhelmed. But with the right approach, it becomes much easier. At Heart Start CPR, we know that memorization alone isn’t enough as you need to truly understand the steps and be able to recall them under pressure.
Whether you’re preparing for an ACLS certification or reviewing your skills, these strategies will help you remember the ACLS algorithm more effectively and feel more prepared in real-life situations.
Understanding the ACLS Framework
Before jumping into memorization, it’s important to understand how ACLS algorithms are structured. They are designed as step-by-step guides to help healthcare providers manage cardiac arrest, arrhythmias, and post-resuscitation care.
The most common ACLS algorithms include:
- Cardiac Arrest (VFib/Pulseless VT, PEA, Asystole) – The steps to take when the heart is not beating effectively.
- Bradycardia (Slow Heart Rate) – Identifying and treating dangerously slow rhythms.
- Tachycardia (Fast Heart Rate) – Determining whether a fast rhythm is stable or unstable and what actions to take.
- Post-Cardiac Arrest Care – The next steps after resuscitation to stabilize a patient.
10 Tips to Memorize ACLS Algorithms Quickly
Learning the ACLS algorithm can be hard. The key is to break the information down, use memory aids, and reinforce your learning through repetition and practice. These ten tips will help you remember ACLS protocols and apply them with confidence.
1. Understand the Logic Behind ACLS Algorithms
Instead of mechanically memorizing steps, focus on why each action is taken. This will help you apply the protocols confidently in real-world scenarios. Ask yourself:
- Why do we give epinephrine in cardiac arrest? (Hint: It improves coronary perfusion and increases the chances of ROSC.)
- When is defibrillation necessary, and when is it ineffective? (Defibrillation works for shockable rhythms like VF and pulseless VT but won’t help in asystole or PEA.)
- Why is early recognition of bradycardia or tachycardia important? (Delaying intervention can lead to hemodynamic instability, cardiac arrest, or worsening arrhythmias.)
2. Use Mnemonics and Acronyms for Easy Recall
Mnemonics are a great way to simplify complex information. Using shortcuts makes it easier to recall important information under stress. Some common ones include:
- NAVEL – Drugs that can be given via an endotracheal tube: Naloxone, Atropine, Vasopressin, Epinephrine, Lidocaine.
- If you’re fast, slow it down. If you’re slow, speed it up. – A simple way to remember how to treat tachycardia versus bradycardia.
- Every Dead Person Attracts Love (EDPAL) – Epinephrine, Defibrillation, CPR, Amiodarone, Lidocaine.

3. Break It Down Into Manageable Sections
Instead of trying to memorize everything at once, focus on one section at a time. Break it down into smaller sections so the information is easier to absorb and retain.
- Start with one algorithm at a time – Don’t rush through everything. Take the time to understand each step before moving on to the next.
- Follow a structured order – Begin with Cardiac Arrest, then move on to Bradycardia and Tachycardia, and finally, review Post-Cardiac Arrest Care to see how it all connects.
- Study in short, focused sessions – Studying for long hours can be exhausting and ineffective. Instead, break your study time into shorter, focused sessions to retain information more efficiently.

4. Utilize Flashcards and Repetition to Help You Remember
Flashcards are a simple but powerful way to reinforce what you learn. Whether you prefer physical flashcards or a digital app, create cards with key information like medications, dosages, and algorithm steps. Take just 5–10 minutes a day to quiz yourself and say the answers out loud—it helps with recall. The more you repeat the information, the more natural it will feel when you need it in a real emergency.
5. Practice with Algorithm Flowcharts and Visual Aids
Many people find it easier to remember information visually rather than by reading paragraphs of text.
- Print out ACLS flowcharts and post them where you study.
- Use color coding to highlight key decision points.
- Draw your own simplified versions to remember key concepts.
6. Engage in Hands-On Training and Simulations
Reading about ACLS is one thing, but practicing it in a real-world setting is what helps the information stick. At Heart Start CPR, our ACLS training includes:
- Realistic emergency scenarios to simulate high-pressure situations.
- Step-by-step guidance from experienced instructors.
- Repetitive practice to reinforce correct responses.
Training in a controlled environment makes it easier to apply ACLS skills in real emergencies.
7. Use Digital Tools, Apps, and Online Quizzes
There are many online resources to help reinforce ACLS concepts, including:
- ACLS Megacode Simulations – Online case studies where you can apply what you’ve learned.
- YouTube tutorials – Watch YouTube videos on step-by-step breakdowns of ACLS protocols.
- ACLS study test – Flashcards and ACLS practice test quizzes to reinforce knowledge.
8. Teach Others to Strengthen Your Retention
Teaching someone else forces you to organize your thoughts and explain ACLS concepts clearly.
- Walk a friend or colleague through a mock scenario.
- Try to explain why each step is necessary instead of just listing steps.
If you can teach it confidently, you know you truly understand it.
9. Apply Real-World Scenarios for Better Context
Instead of memorizing ACLS steps in isolation, think about how they apply in real emergencies. Visualizing actual situations makes it easier to recall protocols under pressure.
Consider these scenarios:
- What should you do if a patient collapses in the hospital hallway? Would you check responsiveness first, call for help, or begin chest compressions?
- How would you manage a patient in the ER experiencing pulseless ventricular tachycardia? Should you start CPR immediately, deliver a shock, or administer medications first?
By putting yourself in these situations, you train your brain to recognize patterns and respond instinctively.
10. Review Regularly and Stay Updated with AHA Guidelines
ACLS guidelines change over time, so it’s important to stay updated. The American Heart Association (AHA) releases updates every 5 years, adjusting medication recommendations and treatment protocols.
You can make a habit of reviewing ACLS material regularly, even after passing your certification. The more often you review, the more confident you will feel when faced with a real emergency.
Common Mistakes to Avoid While Studying ACLS
Many healthcare providers find ACLS challenging, not because the material is too difficult, but because of how they approach studying. Here are some common mistakes that can make learning ACLS harder than it needs to be:
- Trying to memorize steps without understanding why they matter.
- Cramming at the last minute instead of reviewing consistently.
- Skipping hands-on practice.
- Neglecting visual learning tools like flowcharts and diagrams.
- Not staying updated on guideline changes.
