BLS vs. CPR Certification: Which Course Do You Need?

If your employer tells you that you need CPR certification, finding the right class should be simple.

Then you start searching and see terms like:

BLS. CPR. Heartsaver. CPR/AED. First Aid CPR AED. HeartCode BLS.

Suddenly, choosing a class isn't so simple.

One of the most common questions we hear at SPARK CPR is:

“Do I need BLS or regular CPR certification?”

Both courses teach lifesaving CPR and AED skills, but they are designed for different audiences and different workplace requirements.

For most people, the easiest way to determine which course you need is to look at what you do for work and exactly what certification your employer requires.

Here's how BLS and CPR certification differ—and how to choose the right American Heart Association course.

What Is BLS Certification?

BLS stands for Basic Life Support.

The American Heart Association BLS Provider Course is designed primarily for healthcare professionals, trained first responders, and students entering healthcare professions.

The current AHA BLS course teaches participants how to recognize life-threatening emergencies, perform high-quality CPR, provide effective ventilations, use an AED, relieve foreign-body airway obstruction, and function effectively as part of a resuscitation team. The course covers adult, child, and infant patients and reflects the 2025 American Heart Association Guidelines for CPR and Emergency Cardiovascular Care.

Typical BLS students include nurses, physicians, EMTs, paramedics, firefighters, dental professionals, respiratory therapists, medical assistants, healthcare students, and others who may need to perform CPR as part of their professional responsibilities.

SPARK CPR provides American Heart Association BLS certification and renewal courses for healthcare professionals throughout Monroe, Wayne, and Washtenaw counties.

What Do People Mean by “CPR Certification”?

“CPR certification” is often used as a general term, but there isn't just one CPR course for everyone.

For someone outside the healthcare environment, the appropriate American Heart Association course is often a Heartsaver CPR AED or Heartsaver First Aid CPR AED course.

The AHA specifically designed its Heartsaver courses for people with little or no medical training who need CPR, AED, or First Aid training for employment, regulatory requirements, or personal preparedness.

This can include employees working in schools, childcare, manufacturing, construction, fitness, hospitality, security, offices, churches, and many other non-clinical settings.

SPARK CPR offers American Heart Association Heartsaver CPR, AED, and First Aid training for individuals and organizations throughout Southeast Michigan.

What Is the Main Difference Between BLS and Heartsaver CPR?

Both courses teach CPR.

Both teach AED use.

Both can result in an American Heart Association course completion card.

The major difference is who the course is designed for and the level at which the student is expected to respond.

BLS Is Designed for Healthcare Professionals

BLS assumes the student may be responding as part of a professional healthcare or emergency-response team.

The course places additional emphasis on high-quality CPR, ventilations, multiple-rescuer response, team dynamics, and performing CPR in both healthcare and prehospital environments.

Students practice CPR for adults, children, and infants and are tested on specific CPR and AED skills.

Heartsaver Is Designed for Workplace and Community Responders

Heartsaver training is generally designed for people who are not healthcare professionals but need CPR and AED skills for work, regulatory compliance, or emergency preparedness.

The course focuses on recognizing an emergency, activating EMS, performing CPR, using an AED, responding to choking, and—depending on the course selected—providing First Aid.

That makes Heartsaver a strong choice for teachers, coaches, office employees, manufacturing staff, childcare employees, fitness staff, church employees, and other workplace responders.

BLS vs. Heartsaver CPR at a Glance

The American Heart Association states that its BLS Provider Course is intended for healthcare professionals and trained first responders, while Heartsaver courses are intended primarily for people with little or no medical training who need training for work or regulatory purposes.

Who Usually Needs BLS Certification?

If you work directly in healthcare or emergency response, there is a good chance your employer requires BLS rather than a general CPR course.

Common examples include:

• Nurses

• Physicians

• EMTs and paramedics

• Firefighters

• Respiratory therapists

• Dental professionals

• Medical assistants

• Patient-care technicians

• Healthcare students

• Other clinical personnel who may participate in patient resuscitation

However, your job title alone doesn't determine your certification requirement.

A dental office, hospital, nursing program, EMS agency, or healthcare employer may establish specific training requirements.

Always verify the exact course your employer or school requires before registering.

If your requirement specifically says AHA BLS Provider, a Heartsaver card should not be assumed to satisfy that requirement.

Who Usually Needs Heartsaver CPR, AED, and First Aid?

Heartsaver courses are generally better suited for people who need emergency-response training but do not routinely provide medical care as part of their job.

That can include school employees, athletic coaches, childcare workers, manufacturing employees, office staff, security personnel, fitness professionals, construction employees, church staff, and other workplace responders.

The American Heart Association describes Heartsaver First Aid CPR AED as a course for people with little or no medical training who need training for job, OSHA, or other regulatory requirements—or simply want to be prepared for an emergency.

For businesses and organizations that need to train multiple employees, SPARK CPR can also bring onsite CPR, AED, and First Aid training directly to your workplace.

Do Nurses Need BLS or CPR Certification?

Healthcare employers commonly require nurses to maintain BLS Provider certification.

This is because nurses may need to respond to cardiopulmonary arrest as part of a healthcare team rather than solely as a bystander.

BLS training includes adult, child, and infant CPR, AED use, ventilations, and team-based resuscitation skills.

A nurse whose employer specifically requires AHA BLS should therefore register for a BLS Provider course, not a Heartsaver CPR class.

Do Dental Professionals Need BLS?

Many dentists, dental hygienists, dental assistants, and other dental professionals are required by their employer, licensing requirements, or professional setting to maintain CPR training.

Whether that requirement specifically calls for BLS can depend on the employee's role and applicable rules.

Because dental offices may encounter medical emergencies and often employ several people who need certification simultaneously, SPARK CPR can provide onsite group CPR and BLS training directly at dental offices throughout our service area.

Before enrolling, confirm whether your employer requires BLS Provider or another CPR course.

Do Teachers and Coaches Need BLS?

Usually, a healthcare-provider BLS course is not necessary simply because someone is a teacher or athletic coach.

For many school employees, an approved CPR/AED or First Aid CPR AED course such as American Heart Association Heartsaver is more appropriate.

As we discussed in our guide to Michigan school CPR requirements, Michigan has specific CPR and AED training provisions affecting certain teachers and high-school athletic coaches.

The American Heart Association Heartsaver First Aid CPR AED program is among the courses recognized by the Michigan Department of Education for applicable teacher First Aid and CPR requirements.

For schools that need to train several teachers or coaches at once, SPARK CPR offers onsite CPR and AED training for schools.

Is BLS “Better” Than Regular CPR?

Not exactly.

BLS contains additional healthcare-provider skills and team-response components, but that doesn't mean everyone should automatically take BLS.

The best course is the one that matches your role and your requirement.

A nurse working in an emergency department needs different training than an office employee who may respond to a coworker's cardiac arrest.

Likewise, an employee who needs First Aid certification may actually get more relevant workplace training from Heartsaver First Aid CPR AED than from BLS because BLS itself is not a First Aid course.

More advanced isn't always more appropriate.

Does BLS Include First Aid?

No.

This is one of the most common misunderstandings.

BLS teaches high-quality CPR, AED use, ventilations, choking response, and other basic cardiovascular life-support skills.

It is not a general First Aid course.

If your employer requires First Aid, CPR, and AED certification, an American Heart Association Heartsaver First Aid CPR AED course may be the appropriate option unless BLS is separately required.

Some healthcare employees may need both BLS and additional First Aid training depending on their job.

Does BLS Include AED Training?

Yes.

AED use is an important part of BLS.

The current AHA BLS Provider Course includes recognition of cardiac arrest, high-quality CPR, early AED use, ventilations, choking response, and team-based resuscitation.

Heartsaver CPR AED and Heartsaver First Aid CPR AED courses also include AED training.

So the difference between the two courses isn't whether you learn to use an AED.

The difference is the audience, clinical context, and depth of the overall training.

How Long Is BLS Certification Good For?

After successfully completing the requirements of the American Heart Association BLS Provider Course, students receive a BLS Provider course completion eCard that is valid for two years.

American Heart Association Heartsaver CPR/AED and Heartsaver First Aid CPR AED course completion cards are also generally valid for two years.

You should still follow your employer's policies regarding renewal timing.

Waiting until your card has already expired can create unnecessary problems for employment, clinical rotations, credentialing, or workplace compliance.

Can I Take BLS Online?

The American Heart Association offers HeartCode BLS, which uses a blended-learning format.

Students complete the cognitive portion online and then complete an in-person hands-on skills session.

The AHA states that its classroom and blended BLS options teach the same learning objectives and result in the same BLS Provider course completion card.

This can be helpful for healthcare professionals working long or irregular schedules.
