What is Basic Life Support (BLS)?
Ever wondered what you'd do in a life-or-death situation? Basic Life Support (BLS) is like your emergency toolkit for those critical moments. It's a set of skills that anyone can learn to save a life when it really counts. Whether you're a healthcare pro or just someone who wants to be prepared, BLS is all about being the hero in an emergency.
The American Heart Association (AHA) defines Basic Life Support (BLS) as a set of life-saving techniques that focus on maintaining a patient's circulation and breathing through cardiopulmonary resuscitation (CPR) until advanced medical assistance becomes available(1✔ ✔Trusted Source

BLS is a fundamental course provided by the AHA, crucial for healthcare providers, first responders, and qualified bystanders. It equips individuals with the skills needed to respond effectively in emergency situations, potentially making a life-saving difference.
Understanding Basic Life Support Steps
The BLS Algorithm
Basic Life Support follows an algorithm known as ‘the BLS algorithm,’ which is a systematic guide that outlines the steps to be followed in providing BLS. It serves as a crucial tool for healthcare providers and first responders, ensuring a structured approach in critical situations.
- Initial Assessment and Call for Help: The first step in BLS involves quickly assessing the situation and the individual's responsiveness. This helps determine the appropriate course of action.
- Check for Pulse: Check for the pulse of the patient either in the wrist or neck.
- Airway Maintenance: Ensuring an open airway is crucial. Techniques such as the head-tilt chin-lift maneuver can be employed to clear any obstructions.
- Performing Chest Compressions: If the individual is unresponsive and not breathing normally, initiating chest compressions is vital for maintaining blood circulation and oxygenation.
- Rescue Breathing (Ventilation): Providing artificial breaths is essential in cases where the individual is not breathing. Proper technique ensures the delivery of oxygen to the lungs.
- Early Defibrillation: The use of Automated External Defibrillators (AEDs) is crucial in restoring a normal heart rhythm during sudden cardiac arrest(2✔ ✔Trusted Source

ABC vs. CAB Protocol
Before 2010, the ABC sequence was believed to be the right protocol
A: Airway Maintenance
B: Rescue Breathing
C: Circulation/Compressions
In 2010, there was a shift from the traditional ABC sequence, initiated by the American Heart Association to prioritize early chest compressions. This prompt action is crucial for maintaining a steady flow of oxygenated blood to the brain and vital organs. Delays in this critical blood flow can significantly affect a patient's chances of recovery.
Updated BLS Protocol: CAB
The approach to Basic Life Support (BLS) has evolved. The current protocol emphasizes CAB:
C: Circulation/Compressions
A: Airway
B: Rescue Breathing(3✔ ✔Trusted Source

Performing Chest Compressions
Performing effective chest compressions is a crucial component of Basic Life Support (BLS). Here's a step-by-step guide on how to perform chest compressions:
Position Yourself: Ensure that the person in need of assistance is lying on a firm, flat surface. Kneel beside them and locate the center of their chest, which is typically at the nipple line.
Hand Placement: Place the heel of one hand (usually the dominant hand) on the center of the person's chest. If the person is an adult or adolescent, use two hands, one on top of the other.
Interlock Fingers: Interlock your fingers, keeping them straight and ensuring that your palm is not touching the chest.
Position Your Body: Position yourself with your shoulders directly over your hands, keeping your elbows straight. Use your body weight to apply downward pressure during compressions.
Compression Depth: For adults and adolescents, compress the chest at least 2 inches (5 centimeters) deep. For infants, compress about 1.5 inches (4 centimeters) deep.
Compression Rate: Aim for a compression rate of 100-120 compressions per minute.
This is roughly equivalent to the beat of the song "Stayin' Alive" by the Bee Gees.
Allow Full Recoil: Allow the chest to fully recoil between compressions. This means letting it return to its normal position before initiating the next compression.
Minimize Interruptions: Try to minimize interruptions in compressions. Only stop when you need to check for signs of life or to use an AED (if available).
Continue Compressions: Continue performing chest compressions until the person shows signs of life, qualified medical help arrives, or you are physically unable to continue.
Remember, the goal of chest compressions is to circulate oxygenated blood to the brain and vital organs. This is a critical step in maintaining life until professional medical assistance is available. Keep in mind the proper depth, rate, and technique to ensure the best chance of a positive outcome.
Heimlich Maneuver: Technique to Prevent Choking (Infants and Adults)
The Heimlich Maneuver, also known as abdominal thrusts, is a fundamental skill taught in Basic Life Support (BLS) training. It is a critical technique used to dislodge obstructing objects from the airway, potentially saving lives in choking emergencies.
Heimlich Maneuver for Infants
When an infant is choking, it's crucial to approach the situation with care and precision. Here's how the Heimlich Maneuver is performed on an infant:
- Assess the Situation: Confirm that the infant is truly choking and in need of assistance.
- Positioning: Hold the infant face down, with the head lower than the body, resting on your forearm. Ensure that the infant's head and neck are well-supported.
- Back Blows: Use the heel of your hand to deliver five quick, forceful blows to the infant's upper back between the shoulder blades. These back blows are aimed at dislodging the obstructing object.
- Chest Thrusts: After the back blows, carefully turn the infant face up while maintaining head and neck support. Place two fingers in the center of the infant's chest, just below the nipple line. Perform five chest thrusts, pushing downward about 1.5 inches (about 4 centimeters) at a rate of about 100-120 compressions per minute.
- Check the Mouth: After each set of back blows and chest thrusts, check the mouth for the obstructing object. If you see it, carefully remove it with your fingers.
- Continue Until Object is Dislodged: Repeat the sequence of back blows and chest thrusts until the object is expelled and the infant can breathe on their own or when professional medical help arrives.
Heimlich Maneuver for Adults
The Heimlich Maneuver on adults is slightly different due to their size and strength:
- Assess the Situation: Confirm that the adult is truly choking and in need of assistance.
- Positioning: Stand behind the choking adult and wrap your arms around their waist.
- Make a Fist: Place your fist, thumb side in, just above the navel and below the ribcage.
- Perform Abdominal Thrusts: Use quick, upward thrusts with your fists, aiming to force the obstructing object out.
- Continue Until Object is Dislodged: Repeat the abdominal thrusts until the object is expelled and the person can breathe on their own or professional medical help arrives.
It's crucial to remember that if the person becomes unconscious, start CPR immediately. In both cases (infants and adults), seeking professional medical attention is essential after the choking episode, even if the object is successfully dislodged.
Being proficient in the Heimlich Maneuver is a vital skill that can be a lifesaver in emergency situations. Regular BLS training and practice are essential to ensure readiness to respond effectively when it matters most.
Airway Maintenance: Head-up Tilt Chin Technique
The "head-up tilt chin technique," also known as the "head tilt-chin lift maneuver," is a crucial step in basic life support (BLS) for maintaining an open airway in an unconscious person. It is commonly used to clear any obstructions in the airway and facilitate effective breathing.
How is it performed?
Positioning: Approach the unconscious person and kneel beside them.
Hand Placement: Gently place one hand on the person's forehead and the fingers of your other hand under their chin.
Tilt the Head: With the hand on the forehead, apply gentle backward pressure to tilt the head back. This action helps to open the airway by lifting the tongue away from the back of the throat.
Lift the Chin: Simultaneously, use your fingers under the chin to lift it upwards. This helps further extend the neck and ensure a clear passage for air.
Assess Breathing: After performing the head-up tilt chin technique, place your ear close to the person's mouth and nose, while looking at their chest. This allows you to simultaneously listen and feel for breaths.
Look for Chest Rise: Observe if the chest rises and falls, indicating normal breathing.
Listen and Feel for Breath: Use this time to determine if the person is breathing normally, irregularly, or not at all.
This technique is especially important in situations where the person is unresponsive and not breathing normally. It helps create a clear pathway for air to flow into the lungs, facilitating effective respiration. Always remember to approach the person carefully and gently to avoid any further harm or injury. Additionally, if there's any suspicion of a neck or spine injury, it's crucial to use the jaw thrust maneuver instead, as tilting the head back in such cases could be harmful.
Airway Maintenance: Jaw Thrust Maneuver
This maneuver is used when there is a suspicion of a neck or spine injury, and tilting the head back (as in the head-up tilt chin lift technique) could potentially worsen the situation. Here's how the Jaw Thrust Maneuver is performed:
Positioning: Approach the unconscious person and kneel beside them.
Hand Placement: Place your fingers on the angles of the person's lower jaw, near the back of the jawbone.
Lift the Jaw: Gently lift the jaw forward, bringing it slightly upwards. This maneuver helps to move the tongue away from the back of the throat, creating an open airway.
Maintain Head Immobilization: While performing the jaw thrust, ensure that you're stabilizing the person's head and neck to prevent any potential movement that could exacerbate a neck or spine injury.
Assess Breathing: After performing the jaw thrust, check for normal breathing by placing your ear close to the person's mouth and nose, while looking at their chest.
Look for Chest Rise: Observe if the chest rises and falls, indicating normal breathing.
Listen and Feel for Breath: Use this time to determine if the person is breathing normally, irregularly, or not at all.
The Jaw Thrust Maneuver is especially important in scenarios where there's a concern about possible neck or spine injuries, as it minimizes movement in those areas. Remember to perform this technique gently and smoothly to avoid causing any further harm to the person.
Modified Jaw Thrust for Infants: For infants, use a modified jaw thrust maneuver by placing your thumbs on the infant's cheekbones and lifting the jaw upward.
It's crucial to be familiar with both the Head-Up Tilt Chin Technique and the Jaw Thrust Maneuver, as the appropriate technique will depend on the specific situation and the condition of the individual.
Rescue Breaths
How to perform rescue breathing?
Ensure the Airway is Open: Tilt the head back slightly to open the airway.
Give Rescue Breaths
For Adults and Children: Give 1 breath every 5-6 seconds. Each breath should last about 1 second and make the chest visibly rise.
For Infants: Give 1 breath every 3-5 seconds. Each breath should be gentle and cause the chest to rise.
Continue giving rescue breaths until the person starts breathing on their own, or until professional medical help arrives.
Automatic External Defibrillator (AED)
Another important technique in basic life support (BLS) is the Use of Automated External Defibrillators (AEDs).
AEDs are portable electronic devices that are used to analyze a person's heart rhythm and, if necessary, deliver an electric shock to restore a normal heartbeat during sudden cardiac arrest.
How to use an AED?
- Power On the AED: Turn on the AED. Most modern AEDs will have voice prompts that guide you through the process.
- Attach Electrode Pads: Place the electrode pads on the person's bare chest. One pad goes on the upper right chest, just below the collarbone, and the other pad goes on the left side, just below the armpit.
- Analyze Rhythm: The AED will analyze the person's heart rhythm. Make sure no one is touching the person during this process.
- Follow Voice Prompts: If the AED detects a shockable rhythm (such as ventricular fibrillation or ventricular tachycardia), it will instruct you to deliver a shock.
- Stand Clear: Ensure that no one is touching the person, and press the shock button as instructed.
- Resume CPR: After the shock is delivered, immediately resume CPR, starting with chest compressions.
- Continue to Follow AED Prompts: The AED will continue to provide voice prompts, guiding you on when to analyze rhythm and when to deliver additional shocks, if necessary.
Remember, AEDs are designed to be user-friendly and provide clear instructions. They are a critical component of BLS, especially in cases of sudden cardiac arrest, where early defibrillation can greatly increase the chances of survival. It's important to be trained on how to use an AED properly.
