In the high-stakes world of emergency medical care, following standardized procedures can make the difference between life and death. Algorithms in Basic Life Support (BLS) and Advanced Cardiac Life Support (ACLS) provide a systematic approach to critical situations, ensuring that every step is optimized for patient survival. In this blog, we’ll explore seven essential algorithms every medical professional must know to respond effectively in emergencies.
The Adult BLS Algorithm is fundamental for medical professionals and lay rescuers alike. This algorithm provides a clear, step-by-step guide for responding to an unresponsive adult, focusing on early intervention and effective CPR.
1. Assess the Situation:
• Ensure the scene is safe before approaching the patient.
• Check the patient for responsiveness by shaking their shoulders and shouting.
2. Activate Emergency Response:
• If the patient is unresponsive, call for help immediately.
• Send someone to call emergency services and get an Automated External Defibrillator (AED).
3. Start CPR:
• If the patient is not breathing or only gasping, begin chest compressions immediately.
• Place the heel of one hand in the center of the patient’s chest, place the other hand on top, and press hard and fast, at a rate of 100-120 compressions per minute, allowing full recoil between compressions.
4. Use an AED:
• As soon as the AED arrives, turn it on and follow the prompts.
• Attach the AED pads to the patient’s bare chest as indicated.
• Ensure everyone is clear of the patient while the AED analyzes the heart rhythm.
• Deliver a shock if the AED advises it, then immediately resume CPR.
5. Continue CPR:
• Continue cycles of 30 compressions and 2 breaths until advanced medical help arrives or the patient starts to show signs of life.
Importance:
Early CPR and defibrillation significantly increase the chances of survival in cardiac arrest cases. By following the Adult BLS Algorithm, rescuers can provide high-quality care that maximizes the patient’s chances of recovery.
The Pediatric BLS Algorithm is specifically designed to address the unique physiological needs of children from age 1 to puberty. This algorithm emphasizes the importance of tailored compressions and breaths, considering that pediatric cardiac arrests are often due to respiratory issues rather than primary cardiac events.
1. Assess the Situation:
• Ensure the scene is safe.
• Check for responsiveness by tapping the child and shouting.
2. Activate Emergency Response:
• If the child is unresponsive, call for help.
• Have someone call emergency services and retrieve an AED.
3. Check for Breathing and Pulse:
• Look for normal breathing; if the child is not breathing or only gasping, check for a pulse (carotid or femoral) for no more than 10 seconds.
• If there is no pulse, or if the pulse is less than 60 beats per minute with signs of poor perfusion, begin CPR.
4. Start CPR:
• Perform chest compressions at a rate of 100-120 per minute.
• For one rescuer, use a compression-to-breath ratio of 30:2. For two rescuers, use a ratio of 15:2.
• Use one or two hands (depending on the size of the child) to compress the chest about one-third the depth of the chest, approximately 2 inches (5 cm).
5. Use an AED:
• As soon as the AED arrives, turn it on and follow the prompts.
• Attach pediatric AED pads if available; if not, use adult pads ensuring they do not touch.
• Clear the child while the AED analyzes the rhythm and deliver a shock if advised, then resume CPR immediately.
6. Continue CPR:
• Continue cycles of compressions and breaths, switching roles every 2 minutes to avoid fatigue if multiple rescuers are available.
Importance:
The Pediatric BLS Algorithm recognizes that early and effective CPR can prevent deterioration to cardiac arrest caused by respiratory failure or shock. Tailoring the approach to the child’s size and condition helps ensure the best possible outcome in emergencies.
Infant resuscitation requires special considerations due to the delicate physiology of babies under 12 months old. The Infant BLS Algorithm provides a precise guide to ensure high-quality CPR and support until professional help arrives.
1. Assess the Situation:
• Ensure the scene is safe.
• Check for responsiveness by tapping the infant’s foot and shouting.
2. Activate Emergency Response:
• If the infant is unresponsive, call for help.
• Have someone call emergency services and retrieve an AED if available.
3. Check for Breathing and Pulse:
• Look for normal breathing; if the infant is not breathing or only gasping, check for a brachial pulse on the inside of the upper arm for no more than 10 seconds.
• If there is no pulse, or if the pulse is less than 60 beats per minute with signs of poor perfusion, begin CPR.
4. Start CPR:
• Perform chest compressions at a rate of 100-120 per minute.
• Use a compression-to-breath ratio of 30:2 if you are the only rescuer; if there are two rescuers, use a ratio of 15:2.
• Use two fingers for compressions if you are alone, or use the two-thumb encircling technique if there are two rescuers. Compress the chest about one-third the depth of the chest, approximately 1.5 inches (4 cm).
5. Use an AED:
• As soon as the AED arrives, turn it on and follow the prompts.
• Use pediatric pads if available, placing one pad on the front and one on the back of the infant. If pediatric pads are not available, use adult pads ensuring they do not touch.
• Clear the infant while the AED analyzes the rhythm and deliver a shock if advised, then resume CPR immediately.
6. Continue CPR:
• Continue cycles of compressions and breaths, switching roles every 2 minutes to avoid fatigue if multiple rescuers are available.
Importance:
Infants are particularly vulnerable to respiratory issues that can lead to cardiac arrest. The Infant BLS Algorithm focuses on gentle yet effective chest compressions and timely breaths to maintain circulation and oxygenation, increasing the chances of survival and recovery.
Mouth-to-mask ventilation is a vital skill for rescuers, providing effective breaths during CPR while maintaining a safer distance from the patient’s mouth. This method is especially useful in situations where a pocket mask is available and one rescuer is performing CPR.
1. Prepare the Pocket Mask:
• Ensure the mask is clean and ready for use.
• Position yourself at the patient’s head, ensuring you have a good view of their chest.
2. Open the Airway:
• Perform the head-tilt/chin-lift maneuver to open the patient’s airway.
• Avoid hyperextending the neck, especially if a spinal injury is suspected.
3. Seal the Mask:
• Place the mask over the patient’s nose and mouth.
• Use the C-E hand position: form a “C” with your thumb and index finger around the top of the mask, and use the other three fingers to form an “E” by lifting the patient’s jaw and creating a tight seal.
4. Provide Ventilations:
• Deliver a breath over one second, watching for the chest to rise.
• Ensure the breath is just enough to make the chest visibly rise, avoiding over-inflation which can cause gastric inflation and complications.
5. Resume Compressions:
• After providing two breaths, immediately resume chest compressions.
• Continue cycles of 30 compressions and 2 breaths until advanced help arrives or the patient shows signs of life.
Importance:
Mouth-to-mask ventilation is crucial for delivering oxygen efficiently while protecting the rescuer from direct contact with the patient’s mouth. This technique enhances the quality of breaths delivered and ensures that the patient receives adequate oxygenation during CPR.
When two rescuers are available, using a bag-mask device can significantly improve ventilation effectiveness during CPR. This method requires coordination and practice to ensure both rescuers perform their roles efficiently.
1. Positioning:
• One rescuer performs chest compressions while the other handles the bag-mask device.
• The rescuer handling the bag-mask should be positioned at the patient’s head.
2. Open the Airway:
• The rescuer at the head performs the head-tilt/chin-lift maneuver to open the airway.
• If a spinal injury is suspected, use the jaw-thrust maneuver without head extension.
3. Seal the Mask:
• Place the mask over the patient’s nose and mouth.
• Use the E-C clamp technique: form a “C” with your thumb and index finger around the top of the mask, and use the remaining fingers to lift the patient’s jaw, ensuring a tight seal.
4. Provide Ventilations:
• The rescuer at the head squeezes the bag to deliver a breath over one second, watching for chest rise.
• Ensure each breath causes visible chest rise without over-inflating the lungs.
5. Coordinate with Compressions:
• Perform cycles of 30 compressions and 2 breaths if there is only one compressor.
• If two rescuers are performing CPR, switch to a ratio of 15 compressions and 2 breaths.
• Minimize interruptions in compressions during ventilation.
6. Switch Roles Regularly:
• To prevent fatigue, switch roles every two minutes or after five cycles of compressions and breaths.
• Ensure smooth transitions to maintain high-quality CPR.
Importance:
Bag-mask ventilation in two-rescuer CPR is essential for providing effective oxygenation and ventilation while maintaining high-quality chest compressions. Proper technique and coordination between rescuers are critical to maximizing patient outcomes during resuscitation efforts.
The Simple Adult BLS Algorithm, detailed in the ACLS Handbook, provides a streamlined approach to handling unresponsive adults. This algorithm focuses on rapid assessment and immediate intervention to increase the chances of survival.
1. Assess for Responsiveness:

• Check for responsiveness by tapping the patient and shouting.
2. Activate Emergency Response:
• If the patient is unresponsive, call for help immediately.
• Send someone to call emergency services and retrieve an AED.
3. Check for Breathing and Pulse:
• Look for normal breathing. If the patient is not breathing or only gasping, check for a carotid pulse for no more than 10 seconds.
• If there is no pulse, or if you are unsure, begin CPR.
4. Start CPR:
• Perform chest compressions at a rate of 100-120 per minute.
• Use a compression-to-breath ratio of 30:2.
• Place the heel of one hand on the center of the chest, place the other hand on top, and press hard and fast, allowing full recoil between compressions.
5. Use an AED:
• As soon as the AED arrives, turn it on and follow the prompts.
• Attach the AED pads to the patient’s bare chest as indicated.
• Ensure everyone is clear of the patient while the AED analyzes the heart rhythm.

6. Continue CPR:
• Continue cycles of 30 compressions and 2 breaths until advanced medical help arrives or the patient shows signs of life.
• Regularly switch roles with other rescuers to prevent fatigue and maintain high-quality compressions.
Importance:
The Simple Adult BLS Algorithm is crucial for ensuring that unresponsive adults receive timely and effective CPR. By following these steps, rescuers can provide consistent and high-quality care, significantly improving the patient’s chances of survival and recovery.
The Pediatric Chain of Survival emphasizes a series of critical actions that, when performed in sequence, improve the chances of survival and recovery for children experiencing cardiac arrest. Unlike adults, pediatric emergencies often result from respiratory issues rather than cardiac events, making this algorithm especially important for effective intervention.
1. Prevention:
• The first link in the pediatric chain focuses on preventing cardiac arrest by addressing underlying respiratory issues, infections, and other health concerns early.
2. Early CPR:
• Initiate CPR immediately if the child is unresponsive and not breathing normally.
• Perform high-quality chest compressions and provide rescue breaths to maintain circulation and oxygenation.
3. Rapid Activation of EMS:
• Call emergency services as soon as possible to get professional medical help on the way.
• If you are alone, perform CPR for about two minutes before calling EMS, unless the arrest is witnessed.
4. Effective Advanced Life Support:
• Once EMS arrives, ensure effective advanced life support measures are taken, including airway management, IV access, and medication administration.
• Work collaboratively with EMS providers to ensure a smooth transition of care.
5. Integrated Post-Cardiac Arrest Care:
• After return of spontaneous circulation (ROSC), focus on post-cardiac arrest care, including targeted temperature management, maintaining proper ventilation and oxygenation, and monitoring for potential complications.
• Provide support for the child’s physical, cognitive, and emotional recovery.
Importance:
The Pediatric Chain of Survival underscores the need for a comprehensive approach to pediatric emergencies, from prevention to advanced care. By following these steps, healthcare providers can significantly improve the outcomes for children experiencing cardiac arrest, ensuring they receive timely and appropriate care at every stage.
