“Do I need BLS or ACLS?” is one of the most common questions healthcare professionals ask when planning their courses. The answer depends on your role, your unit and your facility’s requirements. This article explains the difference, who each course is for, and how to choose.
What is BLS?
BLS (Basic Life Support) is the foundation of every resuscitation skill. It focuses on early recognition of cardiac arrest, high-quality CPR for adults, children and infants, use of the automated external defibrillator (AED), relief of airway obstruction and working within a resuscitation team.
BLS is a core requirement for most staff in healthcare facilities, clinical and non-clinical alike.
What is ACLS?
ACLS (Advanced Cardiovascular Life Support) builds on BLS and adds the management of complex cardiac events: recognizing life-threatening rhythms on the monitor, resuscitation drugs and doses, advanced airway management, algorithms for cardiac arrest, arrhythmias, acute coronary syndromes and stroke, and leading the resuscitation team.
Because it assumes mastery of the basics, training centers usually require BLS competence before enrolment.
Quick comparison
| Item | BLS | ACLS |
| Level | Basic | Advanced |
| Focus | High-quality CPR and AED | Managing cardiac arrest and arrhythmias, drugs and team leadership |
| Audience | All healthcare practitioners | Physicians and nurses in emergency, critical care and cardiology, and resuscitation team members |
| Prerequisite | None | BLS competence |
| Typical duration | One day | Two days |
How to choose
- General or support units: BLS is the core requirement and is usually enough.
- Emergency, critical care, cardiology or resuscitation teams: you need ACLS in addition to BLS.
- Working with children or newborns: look at PALS (Pediatric Advanced Life Support) and NRP (Neonatal Resuscitation Program), the specialist equivalents.
- In every case: check your facility’s and licensing body’s requirements; they are the final reference.
Card validity and renewal
American Heart Association (AHA) course cards are usually valid for two years. But the skill itself fades faster if it is not practiced, which is why hospitals are moving to short, frequent training on electronic manikins that measure performance, rather than relying on one course every two years.
What makes a good course
- Enough hands-on practice on feedback manikins that measure compression depth and rate.
- Realistic simulation scenarios close to what learners face in their units.
- Certified instructors and a learner-to-instructor ratio that allows individual correction.
- A genuine practical assessment before the card is issued.
Bottom line
BLS is the foundation for every healthcare practitioner; ACLS is the advanced step for those who manage critical cardiac events or lead resuscitation teams. Coral Solutions offers both with realistic simulation scenarios, alongside pediatric and neonatal resuscitation courses and a CPR quality improvement program that maintains skills between courses.
