What is BLS? 

In addition to earning your CPR certification, BLS training is one of the most effective ways to learn important, life-saving skills. BLS, or basic life support, is a medical training course intended to teach essential skills to healthcare workers. While similar to CPR training courses, BLS addresses a broader range of skills and emergency scenarios.

Here, we take a closer look at Basic Life Support and what you learn in these courses. We also discuss the difference between BLS and CPR and look at some of the benefits of earning your BLS certification through 100 percent online courses. 


BLS stands for basic life support and refers to a specific type of medical certification. This certification is designed for those working in the healthcare field and instructs individuals on how to effectively respond to various emergency situations. A BLS course teaches you how to a cardiac arrest episode, obstructed airways, performing CPR, and how to use an automated external defibrillator (AED). 


Basic life support classes can teach you how to safely assess the scene of an emergency, and if necessary, provide chest compressions and ventilation to the victim. These courses also teach you how to safely and effectively use an AED. Here’s a closer look at some of the specific skills that you can learn in a BLS course.

1. Assessing the scene.

Before any action should be taken, a bystander must first assess the scene of the emergency. The last thing you want to do is to put yourself or others in additional danger, which is why these classes teach you how to safely assess the scenario.

2. Adult CPR.

A core component of BLS classes is learning how to properly perform CPR on an adult. Through a combination of chest compressions and rescue breaths, CPR can keep blood and oxygen flowing through the body of someone who experienced cardiac arrest.

3. Child and infant CPR.

While cardiac arrest is much more common in older adults, there are still emergency situations (such as near-drowning or choking) that require CPR for children and infants. While adult CPR and child CPR is similar, there are key distinctions you should make depending on the victim. BLS teaches you how to effectively perform CPR on a victim of any age.

4. Using an AED.

BLS classes also train you on how to properly use an automated external defibrillator (AED). These small medical devices, in tandem with CPR, can aid someone who has experienced cardiac arrest. An AED emits a small electrical shock that essentially resets the victim’s heart.

5. AHA Chain of Survival.

There’s more to responding to a cardiac arrest victim than performing CPR. The AHA Chain of Survival highlights six critical steps, from calling 911 all the way to recovery, to help improve survival rates.

6. Legal issues.

In addition to medical skills, a complete BLS course will also cover various legal considerations you should understand before stepping in at the scene of an emergency. While most states have good Samaritan laws, which protect the rights of anyone attempting to perform CPR, it’s still important to understand the legal implications. 


It’s easy to get confused between BLS classes and CPR classes. While there are similarities, there are also important differences. Make sure to research the details of any medical training course before you enroll.

CPR is a core component of BLS classes, but it isn’t the complete course. While most CPR classes are designed to work for anyone (regardless of your medical experience), BLS courses are intended for healthcare professionals. This means that the information is more specialized and you’ll also learn other skills, such as how to assess the scenario, team basic life support, and legal considerations.
