What is Basic Life Support (BLS)? And How Does it Help in Saving Lives?

Posted November 8, 2021 by in Health + Fitness

Basic Life Support (BLS) is a foundational training for medical professionals and frontline responders who deliver proper care to their patients. It is a level of medical care used in emergency, life-threatening situations until the victim can be cared for professionally at a hospital. It can be helpful for people who are choking or suffering from cardiac arrest, making the difference between life and death. Basic life support is an essential course for all healthcare professionals, and it is included in all first aid training courses and related life-saving techniques and procedures, such as cardiopulmonary resuscitation. CPR can be performed on an individual whose heart has stopped. Its main goal is to buy sufficient time until a specialist arrives. Knowledge of first aid is also important to perform it correctly and this is the reason why first aid is important to learn.

Below you can find out why it’s necessary to get a BLS certification and how it can save someone’s life!

Importance of BLS Certification

Basic life support can save someone’s life. By utilizing these skills, you’ll be able to provide medical support to people in various emergencies. People with BLS certification are capable of saving others from lethal emergencies. However, you need to understand the motive behind basic life support.

This training isn’t about treating or curing a medical condition. It’s about buying some time until the proper medical help arrives. BLS is a very useful method, and you must perform it correctly. That’s why you must complete BLS courses from a reputed institute.

Various institutes offer online training programs that allow you to earn a BLS certification online and help people in need. Fortunately, online education allows you to study at your own pace from the comfort of your house. 

  1. Cardiopulmonary Resuscitation (CPR)

Cardiopulmonary resuscitation (CPR) is a well-recognized technique used in emergencies. It is used to help people who have experienced cardiac arrest. A life-threatening situation occurs when a person’s heart unexpectedly stops beating. Unfortunately, this can lead to brain damage or often death in a few minutes if that person doesn’t get quick medical assistance.

If you find a person collapsing on the floor and not responding, and there is no pulse, you must start CPR to help save his life. Performing CPR techniques involves physically compressing their chest to pump enough blood to their vital organs even when their heart has stopped. Suppose you are one individual, and you want to act to an unresponsive individual. In that case, chest compressions will prove the best way to do that. While you can also perform rescue breaths, the crucial thing is to circulate blood. That’s because when you help circulate blood, passive air exchange can occur in a person’s lungs.

  1. Using an AED to Save a Life

The automated external defibrillator (AED) is a machine that uses an electric shock on someone’s heart to bring it back to the normal rhythm. An AED consists of two pads connected with wires placed directly on an individual’s bare chest. A portable box helps detect the person’s heart rhythm. The automated external defibrillator is a less complicated version of the machine used in hospitals for people during a cardiac arrest. Before using AED on any person, you need to ensure they are unresponsive by checking their lack of pulse. Of course, you will first want to contact emergency medical services for immediate help.

Fortunately, today you’ll find AEDs that are ready to use and well-equipped with audio instructions that allow you to use them properly. Although there is no requirement to get a certification to use AEDs, you must seek proper training to become more confident.

  1. The Heimlich Maneuver Technique

The Heimlich maneuver is among the most helpful techniques to dislodge a food item or any other foreign object stuck in the windpipe. Suppose you notice someone is choking and can’t talk. In that case, you must immediately call emergency medical services (EMS) and try the Heimlich method to help save them. When that person cannot speak, their windpipe is choked, and they can’t breathe. You can also notice other signs of choking, such as covering their throat with their hands (Universal distress signal). The person will turn blue and will gasp for air. The Heimlich maneuver technique is performed by wrapping the arms around the person behind and holding your hands together. Then, you do several upward thrusts toward that individual’s belly button until that foreign object comes out of that person’s mouth. It’s necessary to know that this technique can only be used on adults.

  1. Helps Someone with Compromised Breathing

There are various lethal medical emergencies in which people can’t breathe properly. That means their lungs aren’t receiving a sufficient amount of oxygen. When any such situation arises, you should perform a few specific exercises that can help increase oxygen supply in that individual’s body. One of the best ways is to turn a person on their side. Additionally, you can do another specific beneficial technique, such as the head tilt-chin lift, to save someone’s life. It is a simple maneuver to perform, and you can easily do that by pushing back on the individual’s forehead while slightly pulling their chin upward. It will prevent their soft tissues and tongue from obstructing their airway.


Basic life support skills and techniques will enable you to act promptly in any emergencies before medical assistance arrives. BLS training will help you learn the effective and proper maneuvers for rescuing people in a wide variety of emergencies. The BLS training program includes different life-saving techniques such as CPR, AED, Heimlich maneuver, and more. Everyone needs to learn these skills, especially the frontline healthcare professionals. You will get a BLS certification after completing life-saving training that enables you to help save people’s lives in any situation.
