The BLS full form is Basic Life Support.
It refers to the initial medical care given to a person who is experiencing a life-threatening emergency such as cardiac arrest, breathing failure, or choking—before advanced medical help arrives.
This guide explains BLS in simple language, making it easy for students, beginners, and non-medical readers to understand.
What Is BLS (Basic Life Support)?
Basic Life Support (BLS) is a set of life-saving techniques used to keep a person alive when their heart stops, breathing stops, or their airway is blocked.
BLS focuses on:
- Maintaining blood circulation
- Supporting breathing
- Using an AED (defibrillator) if needed
- Preventing brain damage until medical professionals arrive
Why Is BLS Important?
BLS is critical because:
- Brain damage can start within 4–6 minutes without oxygen
- Early CPR can double or triple survival chances
- Immediate action saves lives in homes, offices, schools, and public places
Even non-medical people can save a life using BLS skills.
Key Components of Basic Life Support
BLS mainly includes the following elements:
Cardiopulmonary Resuscitation (CPR)
- Chest compressions to keep blood flowing
- Rescue breaths (if trained)
Use of AED (Automated External Defibrillator)
- Delivers an electric shock to restore normal heart rhythm
Airway Management
- Ensuring the airway is open and clear
Choking Relief
- Helping someone who cannot breathe due to a blocked airway
BLS Step-by-Step Process (Easy Flow)
- Check safety of the surroundings
- Check response (tap and shout)
- Call for emergency help
- Start CPR (if not breathing normally)
- Use AED as soon as available
- Continue care until help arrives
CPR Basics in BLS
Chest Compressions
- Rate: 100–120 compressions per minute
- Depth: About one-third of chest depth
- Allow full chest recoil
- Minimize interruptions
Compression to Breath Ratio
- 30 compressions : 2 breaths (for trained rescuers)
Types of CPR Used in BLS
Hands-Only CPR
- Only chest compressions
- Recommended for untrained or unsure rescuers
Traditional CPR
- Chest compressions + rescue breaths
- Used by trained individuals
Role of AED in BLS
An AED:
- Is portable and easy to use
- Gives voice instructions
- Detects abnormal heart rhythm
- Delivers shock only if needed
Using an AED early greatly increases survival chances.
Choking Management in BLS
Signs of Choking
- Unable to speak or breathe
- Hands on throat
- Blue or pale skin
- Weak or no coughing
5 & 5 Method
- 5 back blows
- 5 abdominal thrusts
Repeat until blockage clears or help arrives
Who Should Learn BLS? (Often Missing in Competitor Articles)
BLS is not only for doctors. It is useful for:
- Students
- Teachers
- Office workers
- Security staff
- Parents
- Drivers
- Fitness trainers
- General public
Anyone can become a life saver with BLS knowledge.
