When it comes to cardiac emergencies, time is of the essence. The Chain of Survival is a crucial concept that every medical professional must understand and implement swiftly to increase a patient’s chances of survival.
The Chain of Survival consists of the following critical steps:
1. Early Recognition and Call for Help
• Identifying cardiac arrest quickly and calling for emergency medical services (EMS) immediately.
• Time saved at this stage can significantly impact the patient’s outcome.
2. Early CPR
• Starting high-quality chest compressions immediately to maintain blood flow to vital organs.
• Ensuring compressions are deep enough and at the correct rate (100-120 compressions per minute).
3. Rapid Defibrillation
• Using an Automated External Defibrillator (AED) as soon as it is available.
• The AED can restore a normal heart rhythm in cases of sudden cardiac arrest due to ventricular fibrillation.
4. Advanced Life Support
• Administering advanced medical care by trained professionals.
• This includes airway management, medications, and other interventions.
5. Post-Cardiac Arrest Care
• Comprehensive care after the return of spontaneous circulation (ROSC).
• Focus on stabilizing the patient, preventing complications, and addressing underlying causes.
6. Recovery
• Added in the 2020 guidelines, emphasizing the importance of recovery and rehabilitation.
• Includes physical, cognitive, and emotional support for the patient and debriefing for rescuers.
Understanding and efficiently executing each link in the Chain of Survival is paramount. Early initiation of BLS has been shown to dramatically increase the likelihood of survival and recovery for cardiac arrest victims.
Staying updated with the latest guidelines is essential for providing the best care possible. The 2020 BLS guidelines introduced several significant changes aimed at improving the effectiveness of life-saving measures. Here are the key updates:
1. Emphasis on Early CPR by Lay Rescuers
• The importance of initiating CPR by bystanders has been re-emphasized.
• The risk of harm to the patient is low if they are not in cardiac arrest, so bystanders should not hesitate to start CPR even if they are unsure about the patient’s condition.
2. Addition of the Recovery Link in the Chain of Survival
• A sixth link, Recovery, has been added to both Adult and Pediatric Chains of Survival.
• This highlights the need for ongoing care after the return of spontaneous circulation (ROSC), including physical, cognitive, and emotional support for the patient.
3. Post-Cardiac Arrest Care
• Close attention is required for oxygenation, blood pressure control, and evaluation for percutaneous coronary intervention after ROSC.
• Targeted temperature management and multimodal neuroprognostication are crucial for recovery.
4. Mental Health Support for Rescuers
• After a resuscitation effort, debriefing for lay rescuers, EMS providers, and hospital-based healthcare workers is beneficial.
• This support helps address the mental health and well-being of those involved in the resuscitation.
5. Management of Cardiac Arrest in Pregnancy
• Maternal resuscitation focuses on the mother, with preparation for early perimortem cesarean delivery if necessary to save the infant and improve maternal resuscitation success.
These changes underscore the continuous evolution of BLS practices based on the latest research. By understanding and applying these updates, medical professionals can enhance their life-saving techniques and provide better care during emergencies.
Providing effective Basic Life Support (BLS) to adults requires understanding and executing several critical steps. Here’s a step-by-step guide:
1. Scene Safety and Assessment
• Before approaching the patient, ensure the scene is safe for both the rescuer and the patient.
• Check the patient for responsiveness by tapping and shouting. If there is no response, shout for help.
2. One-Rescuer BLS/CPR Technique
• Call EMS: If alone, call emergency services immediately and get an Automated External Defibrillator (AED) if available.
• Check Breathing and Pulse: Assess for normal breathing and check the carotid pulse for no more than 10 seconds. If unsure, begin CPR.
• Chest Compressions: Place the heel of one hand on the center of the chest, and the other hand on top. Perform chest compressions at a depth of at least 2 inches (5 cm) at a rate of 100-120 per minute.
• Rescue Breaths: Open the airway using the head-tilt/chin-lift maneuver. Give 2 breaths, each over 1 second, watching for chest rise.
3. Two-Rescuer BLS/CPR Technique
• One rescuer performs chest compressions while the other manages the airway and provides rescue breaths.
• Switch Roles: Rescuers should switch roles every 5 cycles of 30 compressions and 2 breaths to prevent fatigue and maintain high-quality compressions.
4. Use of Automated External Defibrillator (AED)
• Turn on the AED: Follow the prompts provided by the device.
• Attach AED Pads: Place one pad on the upper right side of the chest and the other on the lower left side.
• Analyze Rhythm: Allow the AED to analyze the heart rhythm. Ensure no one is touching the patient during this time.
• Deliver Shock if Advised: If a shock is advised, ensure everyone is clear of the patient and press the shock button. Immediately resume CPR after the shock.
Performing BLS effectively requires practice and adherence to these steps. The combination of high-quality chest compressions, timely rescue breaths, and prompt use of an AED can significantly improve the chances of survival in adults experiencing cardiac arrest.
BLS for children and infants requires modifications to account for their smaller size and different physiological responses. Here’s a detailed guide:
1. Differences Between Adult and Pediatric BLS
• Children and infants often suffer from respiratory emergencies that lead to cardiac arrest, unlike adults who typically experience primary cardiac events.
• The compression to breath ratio differs: 30:2 for one-rescuer and 15:2 for two-rescuers in pediatric cases.
2. One-Rescuer BLS for Children
• Scene Safety and Assessment: Ensure the scene is safe. Tap the child and shout to check for responsiveness.
• Call for Help: If alone, perform CPR for about 2 minutes before calling emergency services if the collapse was unwitnessed.
• Chest Compressions: Use one or two hands (depending on the size of the child) to perform compressions at a depth of about 2 inches (5 cm). Perform 30 compressions followed by 2 breaths.
• Rescue Breaths: Open the airway with the head-tilt/chin-lift maneuver and give 2 breaths, watching for chest rise.
3. Two-Rescuer BLS for Children
• Scene Safety and Assessment: Ensure the scene is safe. Tap the child and shout to check for responsiveness.
• Call for Help: Send the second rescuer to call emergency services and get an AED.
• Chest Compressions: One rescuer performs 15 compressions while the other gives 2 breaths.
• Switch Roles: Rescuers should switch roles every 5 cycles to maintain high-quality compressions.
4. One-Rescuer BLS for Infants
• Scene Safety and Assessment: Ensure the scene is safe. Tap the infant’s foot and shout to check for responsiveness.
• Call for Help: If alone, perform CPR for about 2 minutes before calling emergency services if the collapse was unwitnessed.
• Chest Compressions: Use two fingers to perform compressions at a depth of about 1.5 inches (4 cm). Perform 30 compressions followed by 2 breaths.
• Rescue Breaths: Cover the infant’s mouth and nose with your mouth and give 2 gentle breaths, watching for chest rise.
5. Two-Rescuer BLS for Infants
• Scene Safety and Assessment: Ensure the scene is safe. Tap the infant’s foot and shout to check for responsiveness.
• Call for Help: Send the second rescuer to call emergency services and get an AED.
• Chest Compressions: One rescuer uses the two-thumb encircling hands technique to perform 15 compressions while the other gives 2 breaths.
• Switch Roles: Rescuers should switch roles every 5 cycles to maintain high-quality compressions.
Understanding and applying these pediatric-specific techniques can significantly improve outcomes in emergencies involving children and infants.
Effective airway management and rescue breathing are critical components of BLS. Here’s a guide on how to perform these techniques:
1. Mouth-to-Mouth Ventilation
• Adults and Older Children
• Open the Airway: Use the head-tilt/chin-lift maneuver. Avoid this if you suspect a neck injury.
• Seal the Mouth: Pinch the victim’s nose shut and create a seal over their mouth with yours.
• Deliver Breaths: Give 2 breaths, each lasting about 1 second, and watch for the chest to rise.
- Resume Compressions: If the chest does not rise, retilt the head and try again.
2. Mouth-to-Mouth/Nose Ventilation for Infants
• Open the Airway: Use the head-tilt/chin-lift maneuver, ensuring a neutral position.
• Seal the Mouth and Nose: Cover both the infant’s mouth and nose with your mouth.
• Deliver Breaths: Give 2 gentle breaths, each lasting about 1 second, and watch for the chest to rise.
• Alternative Technique: If you cannot cover both the mouth and nose, pinch the nose shut and seal your mouth over the infant’s mouth.
3. Mouth-to-Mask Ventilation
• Position the Mask: Place the mask over the victim’s face, covering the nose and mouth.
• Create a Seal: Use one hand to hold the mask in place, forming a “C” shape with your thumb and index finger, and the other hand to lift the jaw.
• Open the Airway: Use the head-tilt/chin-lift maneuver.
• Deliver Breaths: Give breaths through the mask, watching for chest rise.
4. Bag-Mask Ventilation
• Two-Rescuer Technique: One rescuer performs chest compressions while the other manages the bag-mask.
• Create a Seal: Place the mask on the victim’s face and form a seal using the “E-C clamp” technique.
• Open the Airway: Use the head-tilt/chin-lift maneuver.
• Deliver Breaths: Squeeze the bag to give breaths, each lasting 1 second, and watch for chest rise.
These techniques ensure that adequate ventilation is provided to the patient, maintaining oxygenation and increasing the chances of survival until advanced care is available. Proper airway management and rescue breathing can make a significant difference in the outcome of a cardiac arrest situation.
Choking is a common and preventable cause of cardiac arrest. Recognizing and responding to choking emergencies promptly is crucial. Here’s how to manage choking in different age groups:
1. Choking in Adults and Children (Over One Year Old)
• Mild Obstruction
• The person can breathe, cough, and make sounds.
• Encourage them to keep coughing to expel the object.
• Stay with them and monitor their condition.
• Severe Obstruction
• The person cannot breathe or make sounds and may clutch their throat (universal choking sign).
• Abdominal Thrusts (Heimlich Maneuver):
• Stand behind the person and wrap your arms around their waist.
• Place a fist above their navel and grasp it with your other hand.
• Perform quick, upward thrusts into the abdomen.
• Continue until the object is expelled or the person becomes unresponsive.
• If the Person Becomes Unresponsive:
• Lower them to the ground and begin CPR.
• Check the mouth for the object each time you open the airway to give breaths.
2. Choking in Infants (Under One Year Old)
• Mild Obstruction
• The infant can breathe, cough, and make sounds.
• Encourage coughing and monitor their condition closely.
• Severe Obstruction
• The infant cannot breathe, cough, or make sounds and may turn blue.
• Back Blows and Chest Thrusts:
• Hold the infant face down on your forearm, supporting the head and neck.
• Deliver 5 firm back blows between the shoulder blades with the heel of your hand.
• If the object is not expelled, turn the infant face up, supporting the head.
• Give 5 quick chest thrusts using two fingers, pressing on the lower half of the breastbone.
• Repeat the sequence of back blows and chest thrusts until the object is expelled or the infant becomes unresponsive.
• If the Infant Becomes Unresponsive:
• Place the infant on a firm, flat surface and begin CPR.
• Check the mouth for the object each time you open the airway to give breaths.
3. Self-Assessment for Relief of Choking
• Scenario 1: A 21-year-old college student collapses while eating and turns blue.
• Likely cause: Choking.
• Next step: Perform abdominal thrusts.
• Scenario 2: A daycare provider finds a 3-year-old unresponsive and not breathing.
• Next step: Perform 2 minutes of CPR before calling 911/EMS if alone.
• Scenario 3: An infant is not breathing and has a weak pulse.
• Next step: Begin CPR if the pulse is less than 60 beats per minute.
Knowing how to manage choking emergencies effectively can save lives. Prompt and appropriate intervention can prevent a minor incident from becoming a life-threatening situation.
