ACLS (Advanced Cardiovascular Life Support) training covers the advanced skills healthcare providers use when a patient's heart or breathing fails: rhythm recognition, emergency medications, airway management, and team leadership. You demonstrate those skills in a hands-on test and then pass a written exam. If you are wondering what is included in ACLS training, the short answer is that it is far more practical than most people expect, and most of the class is spent practicing rather than listening. This article walks through each component so you know what to expect, how the course formats differ, and how to prepare before you sign up with Best Emergency Services Training.
Who ACLS Is Built For and What You Should Know Beforehand
ACLS is designed for people who manage cardiac arrest and other cardiovascular emergencies as part of their work: physicians, nurses, paramedics, respiratory therapists, and other clinicians in acute care, emergency, critical care, and similar settings. It is not a general public course. Laypeople who want CPR training are better served by a CPR and AED class, and most healthcare students start with BLS before moving on.
The AHA expects you to arrive with certain knowledge. In practice, that means:
- A current BLS Provider card, or at least BLS skills you can perform correctly on the day.
- Comfort reading basic ECG rhythms, including normal sinus rhythm, ventricular fibrillation, and the common tachycardias and bradycardias.
- Familiarity with the drugs commonly used in resuscitation, so that the names and purposes are not new to you.
The AHA publishes a pre-course self-assessment for ACLS, and it is worth taking seriously. It shows quickly whether your rhythm and pharmacology knowledge is where it needs to be. Check the current requirements for your specific course with your instructor, since wording and tools can change.
The most common mistake
Many learners assume ACLS replaces BLS. It does not. High-quality CPR is the foundation the whole course builds on, and you will be evaluated on compressions, ventilations, and minimizing interruptions throughout the scenarios. A provider who knows every drug but delivers shallow, interrupted compressions will struggle in the megacode.
If your BLS skills are rusty, Best Emergency Services Training can help you refresh them before your ACLS class, so you walk in confident about the fundamentals rather than relearning them under test pressure.
The Core Clinical Content: Algorithms, Rhythms, and Medications
The clinical heart of ACLS is a set of decision pathways called algorithms. An algorithm is a step-by-step flowchart that tells the team what to assess and do next based on the patient's condition. A few terms come up constantly:
- VF/pVT: ventricular fibrillation and pulseless ventricular tachycardia, the shockable rhythms.
- Asystole: no electrical activity, a nonshockable rhythm.
- PEA: pulseless electrical activity, where the monitor shows organized electrical activity but there is no pulse.
- ROSC: return of spontaneous circulation, the point at which the heart restarts effectively.
The main algorithms
Expect to work through the cardiac arrest algorithm, bradycardia, tachycardia with a pulse, acute coronary syndromes, and acute stroke. The cardiac arrest pathway is the centerpiece. It splits on rhythm: shockable rhythms lead to defibrillation, while asystole and PEA focus on high-quality CPR, medications, and identifying reversible causes. The other pathways teach you to assess whether an unstable patient needs pacing, cardioversion, or medication, and how to move quickly on chest pain and stroke symptoms.
Why rhythm recognition drives everything
You cannot choose the right pathway without reading the rhythm. Misidentifying VF as PEA means a missed shock; treating a stable tachycardia as unstable means unnecessary cardioversion. That is why the course spends real time on ECG interpretation, and why the pre-course self-assessment matters.
Medications
The course discusses drug categories used across the algorithms, including vasopressors such as epinephrine, antiarrhythmics such as amiodarone, adenosine for certain supraventricular tachycardias, and atropine for symptomatic bradycardia. You learn what each drug is for, when it appears in the pathway, and the cautions that go with it. Doses and timing belong in your course materials, not in an article: always confirm them against the current AHA provider manual and guidelines, since details are revised over time.
The AHA updates its resuscitation guidelines periodically, and as of 2026 instructors teach from the current AHA guideline cycle. Because content can shift between cycles, rely on the manual and algorithm cards your class provides. Many classes also allow reference tools, so you are not expected to memorize every number, but confirm the policy for your session.
Hands-On Skills Practiced in Class
ACLS is taught in person with an instructor and manikins, and the skills portion is where most of your time goes. The format rewards repetition: you perform a task, get specific feedback, and do it again until it is automatic.
High-quality CPR and bag-mask ventilation
You practice compressions to AHA standards for depth, rate, and full chest recoil, often with feedback devices on the manikin that show whether you are on target. You also use a bag-mask device, which is harder than it looks. Getting a good mask seal and delivering effective breaths while a partner compresses is a skill that improves only with practice.
Airway management
The course covers basic airway adjuncts and gives an overview of advanced airway concepts, such as supraglottic devices and endotracheal intubation. The key lesson is how airway work fits around compressions: the goal is to avoid long pauses, so advanced airway placement should not interrupt chest compressions more than necessary. Confirm with your instructor how deeply your session covers each device, since emphasis varies by course design.
Defibrillation and cardioversion
You will use both an AED and a manual monitor/defibrillator. For manual devices, you learn to charge, clear the patient, deliver the shock, and resume compressions immediately. You also practice the safe-shock steps: verbal clearance, a visual check that no one is touching the patient or bed, and attention to oxygen sources. Synchronized cardioversion for unstable tachycardia is covered as well, including why it differs from defibrillation.
IV/IO access
Vascular access, through IV or intraosseous routes, is part of medication delivery and is discussed in the course. Whether you physically practice placement depends on the course format and equipment, so ask your training provider what your session includes if that matters for your role.
Team Dynamics and Megacode Scenarios
Resuscitation is a team effort, and the AHA treats team behavior as a core skill, not an add-on. In ACLS you rotate through team leader and team member roles. The leader assigns tasks, watches the big picture, and makes decisions. Members perform their assigned tasks and speak up when they notice a problem.
Three habits are emphasized repeatedly:
- Closed-loop communication: the leader gives a clear instruction, the team member repeats it back, then confirms when it is done.
- Clear roles: everyone knows who is on compressions, airway, monitor, and medications.
- Mutual respect: constructive feedback and the freedom to question a decision without conflict.
What a megacode looks like
A megacode is a simulated patient case in which each learner takes a turn leading the team through changing rhythms and decisions. Imagine a scenario in which a patient is found unresponsive and pulseless in VF. As team leader, you direct compressions, confirm the rhythm, call for a shock, and request IV or IO access. After a round of CPR and a drug, the rhythm changes. Perhaps a pulse returns, and now you are managing a patient with ROSC.
That is where post-cardiac arrest care comes in. You review the basics: optimizing oxygenation and blood pressure, obtaining a 12-lead ECG, considering the cause of the arrest, and thinking about temperature management and transfer to appropriate care. The scenario ends when you have shown you can lead the full sequence, not just the shock.
Freezing as team leader
It is common to blank when you first lead. The scenario moves quickly, and the algorithm in your head suddenly feels blurry. Instructors expect this and coach during practice rounds, prompting you to restate what you see, name the rhythm, and choose the next step. Speaking your thinking out loud is the best way through it, and it is exactly what a real team leader does.
Testing, Certification Card, and Renewal
ACLS assessment has two parts. The first is a hands-on skills evaluation, which typically includes a CPR and AED skills test and a megacode in which you lead a scenario. The second is a written exam covering the algorithms, rhythms, pharmacology, and team concepts. The AHA sets the passing score and format, and these can change, so confirm the current details with your instructor before test day rather than relying on a number you saw elsewhere.
If you pass, you receive an AHA ACLS Provider card. As of 2026, AHA cards are valid for two years and are issued as eCards, which you claim online and can download or print. Delivery details can vary by training center, so ask how and when yours will arrive.
Initial versus renewal courses
An initial ACLS course is the full-length format for first-time students or those whose card has lapsed beyond what the renewal format allows. A renewal (update) course is shorter and designed for providers who hold a current ACLS card and are renewing before it expires. It assumes you already know the material and focuses on refreshing it and retesting. Eligibility rules, including how much grace there is after expiration, are set by the AHA and the training center, so check before booking. Letting a card expire often means repeating the longer initial course.
Check your employer's requirements
Hospitals, clinics, and licensing bodies sometimes have their own rules about which course format they accept, how long before expiration you may renew, or whether specific certifications are required for your unit. A quick message to your manager or education department before you register can save you from paying for a class that does not satisfy your employer.
Course Formats and How to Choose One
ACLS comes in two main formats. An instructor-led classroom course delivers everything in person. A blended learning option has you complete the cognitive portion online, then attend an in-person skills session with an instructor. Both lead to the same AHA card, because both include a hands-on component.
That hands-on requirement is the line that separates real certification from a lookalike. A legitimate AHA card requires in-person skills practice and testing with an instructor. A fully online-only certificate, with no hands-on evaluation, is not AHA certification, and many employers will reject it.
Options at Best Emergency Services Training
Best Emergency Services Training offers several ways to complete ACLS: classes at multiple offsite locations, onsite group training for hospitals, practices, and other organizations, and one-on-one or home instruction for learners who need a more personal setting. Accommodations are available for physical limitations, so tell us what you need when you schedule.
A checklist for choosing a class
- Confirm the course is AHA-authorized and that you will receive an AHA eCard.
- Ask about the instructor-to-student ratio. Smaller groups mean more manikin time and more coaching during megacodes.
- Check how quickly you can get a session, especially if a deadline is close.
- Ask what the fee includes, such as the provider manual, the eCard, or the online portion. Fees change, so verify the current price directly as of your booking date.
How to prepare
Complete the pre-course self-assessment and review any weak spots. Study the algorithms until you can describe the logic, not just the boxes. Practice reading rhythm strips. Finally, bring your current BLS card to class, along with any materials your training provider asks for.
Putting ACLS Together: Knowledge, Skills, and Leadership
ACLS combines algorithm knowledge, hands-on skills, team leadership, and testing into one course, and each piece supports the others. Before you book, check your BLS status: if your card is current and your skills are sharp, you are ready to start, and if not, a quick refresher will make the ACLS class far smoother.
