BLS vs CPR:
What's the Difference?

One of the most common questions we get before booking a class is: "Do I need BLS or CPR?" It's a fair question — the terms get used interchangeably all the time, including by people who should know better. But they're not the same thing, and choosing the wrong one can leave you or your team out of compliance with licensing or employment requirements.

Here's the clear breakdown.

What Is CPR?

CPR stands for Cardiopulmonary Resuscitation. It's the physical act of manually compressing the chest and delivering rescue breaths to keep blood and oxygen circulating when someone's heart has stopped. CPR is a skill — not a certification level.

When most people say they need "CPR certification," they typically mean the American Heart Association Heartsaver CPR and AED course — the standard certification for the general public, workplaces, schools, and anyone who isn't a licensed healthcare provider.

What Is BLS?

BLS stands for Basic Life Support. The full course name is BLS for Healthcare Providers, and it's designed specifically for people who work in clinical settings — nurses, physicians, medical assistants, dentists, dental hygienists, physical therapists, EMTs, and other licensed healthcare professionals.

BLS covers everything in the Heartsaver course, plus additional clinical skills that healthcare providers need:

• Bag-mask ventilation — using a BVM device to deliver rescue breaths
• 2-rescuer CPR — coordinating with another provider during resuscitation
• Advanced airway management techniques
• Team-based resuscitation protocols used in clinical environments

BLS is a higher level of certification than Heartsaver CPR — it assumes the learner will be working in a clinical environment with equipment and other trained providers available.

Side-by-Side Comparison

Which One Do You Need?

Here's the simple rule:

If you are a licensed healthcare provider or work in a clinical setting — you need BLS. This includes nurses, physicians, dentists, dental hygienists, medical assistants, physical therapists, occupational therapists, EMTs, and any other role where BLS is specifically required by a licensing board or employer.

If you work in a business, school, daycare, or non-clinical workplace — you need Heartsaver CPR and AED. This satisfies OSHA compliance requirements, California Title 22 for childcare, and the general workplace safety standard for non-clinical environments.

Can BLS Replace Heartsaver CPR?

Yes — BLS is a higher-level certification that satisfies any requirement that Heartsaver CPR would satisfy. If you hold current BLS certification, you meet the requirements for both clinical and non-clinical settings.

However, Heartsaver CPR does not satisfy BLS requirements. A dental assistant who takes a standard Heartsaver class is not compliant with California Dental Board licensing requirements — they need BLS.

What About First Aid?

First Aid is a separate training component that covers bleeding control, burns, fractures, allergic reactions, shock, and other non-cardiac emergencies. It's not included in the standard BLS for Healthcare Providers course — but it is commonly bundled with Heartsaver CPR for workplace and childcare compliance.

For most businesses and schools, we recommend the combined Heartsaver CPR, AED and First Aid course — it covers everything in one session and satisfies both OSHA and Title 22 requirements.

Frequently Asked Questions

I got CPR certified years ago. Does that still count?

Only if it's still current. AHA certification is valid for two years. If your card has expired, you need to recertify — past certification doesn't carry forward.

My employer says I need "healthcare CPR" — is that BLS?

Almost certainly yes. "Healthcare CPR," "professional rescuer CPR," and "CPR for healthcare providers" all refer to the AHA BLS for Healthcare Providers course.

Is there a difference between BLS renewal and a new BLS course?

Not significantly. Both result in the same two-year AHA certification card. Renewal courses may be slightly shorter since participants are already familiar with the material, but both include a full hands-on skills component.

Can I take BLS instead of Heartsaver to over-certify?

Yes — BLS satisfies all Heartsaver requirements plus the additional clinical requirements. If your team includes a mix of healthcare and non-healthcare staff, we can certify everyone with BLS in a single session.
