BLS vs CPR: What’s the Difference & Which Certification Do You Need?

BLS and CPR are not the same. While both teach life-saving techniques, BLS (Basic Life Support) is a more advanced certification designed for healthcare professionals, while CPR is a foundational course intended for the general public. Choosing the right certification depends on your role, responsibilities, and the level of training required.

In this blog we will break down the key differences between BLS and CPR, explain what each certification covers, and help you determine which one is right for you.

BLS vs CPR: What’s the Difference?

If you think BLS is just a fancy acronym for CPR, you’re not alone – but you would be mistaken. This is a common misconception since BLS certification does have some overlap with CPR certification. However, there are stark differences in the depth and scope of the skills taught in each course. This article will illuminate the essential differences between BLS versus CPR certification so that you can make the right call when it comes to choosing a course.

What Is BLS Certification?

Basic Life Support , or BLS, is a training program developed by the American Heart Association (AHA) that teaches skills for recognizing and responding to life-threatening cardiac and respiratory emergencies. Per the AHA, these skills “address the treatment of cardiac arrest as well as other immediately life-threatening conditions including respiratory arrest and FBAO [foreign body airway obstruction].”

Who Needs BLS Certification?

BLS certification is required for healthcare professionals (nurses/physicians/medical assistants) as well as first responders (EMTs, firefighters, and police officers) who expect to encounter patients with life-threatening emergencies. BLS certification is also required for other lesser-known positions such as nursing students, medical students, lifeguards and swimming instructors.

What BLS Training Covers

BLS training covers all of the material for CPR certification, including compressions, rescue breaths and AED usage, but covers even more:

• Multi-rescuer CPR techniques
• Bag-valve mask (BVM) usage
• Foreign-body airway obstruction management (including conscious and unconscious patients)

What Is CPR Certification?

CPR certification is a more focused training that teaches a narrower range of skills for responding to life-threatening cardiac emergencies. The training is typically meant for laypersons with the goal of increasing survival rates in cardiac arrest scenarios. The idea is to empower bystanders to begin life-saving compressions and basic interventions until EMS arrives to take over.

Who Needs CPR Certification

This training is typically taught to non-healthcare personnel and bystanders including teachers, coaches, caregivers and security staff who need to understand the basics of performing CPR in an emergency situation until EMS or other professional healthcare providers arrive. At the end of the day, anyone can take this training and benefit from it, but many non-healthcare employers will still require or offer the training for their staff.

What CPR Training Covers

CPR training covers the basics for life threatening cardiac emergencies, including:

• Recognizing cardiac arrest
• Performing high-quality chest compressions
• Performing rescue breaths
• Using an AED

Key Differences Between BLS and CPR

As you can see, there are marked differences between BLS and CPR certification in terms of the scope, personnel and settings for which they are required. The primary differences between these two certifications pertain to the level of training provided, the target audience and the skills covered in the course.

Level of Training

BLS certification provides a more comprehensive training that allows for advanced resuscitation techniques, typically in healthcare settings. Conversely, CPR has a more basic, focused approach that can be adopted in any scenario, inside or outside of a healthcare setting.

Target Audience

BLS certification is primarily geared toward healthcare professionals, first responders, and other healthcare-adjacent positions (students/lifeguards). CPR certification, on the other hand, is accessible to all non-healthcare individuals including teachers, coaches, and security staff.

Skills Covered

BLS certification covers all of the education within CPR certification but also includes more advanced techniques such as multi-rescuer CPR, BVM usage, and foreign body airway obstruction (FBAO) management. CPR certification focuses on the essentials of the technique, including performing high quality chest compressions, rescue breaths, and use of an AED.

Now that you’ve learned some of the essential differences between BLS and CPR certification, you can decide what path is best for you. See the following chart to determine which course best meets your needs:

Additionally, the decision of whether to pursue BLS or CPR certification will often be dictated by your occupation, being dependent on whether you are in a healthcare setting or not. See the following chart for further direction:

Can You Take BLS or CPR Certification Online?

Is it possible to take a BLS or CPR certification course online? Thankfully, the answer is yes! Both BLS and CPR courses are available in online-only formats. Be aware, though, that some employers may require a certification course with an in-person skills check off or other additional trainings, so be sure to verify with your employer that an online-only format is acceptable before registering. Other formats may be hybrid or “blended”, utilizing an online portion for the didactic portion and an in-person skills check to complete the training.
