General Concepts
Main Components of CPR (C - A - B)
The main components of CPR are often remembered as "C-A-B," representing Chest Compressions, Airway, and Breathing. These components are critical in maintaining blood circulation and oxygen supply to vital organs, increasing the chances of survival until advanced medical help arrives.
C - Chest Compressions: Chest compressions are the foundation of CPR. They help circulate oxygen-rich blood to vital organs, especially the brain. Proper technique is crucial to ensure effectiveness. To perform Chest Compressions:
- Place the heel of one hand on the center of the victim's chest (lower half of the sternum).
- Use the other hand to interlace fingers and keep the elbows straight.
- Compress the chest at least 2 inches deep (adults) at a rate of 100-120 compressions per minute.
- Allow the chest to recoil fully between compressions.
A - Airway: Establishing an open airway is vital for effective ventilation and the delivery of oxygen to the lungs. Ensure the victim's airway is clear of any obstructions. To open the airway:
- Tilt the victim's head backward gently while lifting the chin up with two fingers.
- Look, listen, and feel for signs of breathing for no more than 10 seconds.
B - Breathing: Once the airway is open, provide rescue breaths to deliver oxygen to the victim's lungs. This step is particularly important if the victim is not breathing normally. To provide Rescue Breaths:
- Maintain an effective seal over the victim's mouth and nose.
- Deliver 2 rescue breaths after every 30 chest compressions.
- Each breath should last about 1 second and make the chest rise visibly.
High-Quality CPR
High-quality CPR is crucial for increasing the chances of survival in cardiac arrest situations. It involves a combination of effective chest compressions, maintaining an open airway, and providing adequate ventilation. Here is a CPR cheat shthe key elements of high-quality CPR:
- Early Recognition and Activation: Recognize the signs of cardiac arrest and activate the emergency response system immediately. Early activation ensures that professional help is on the way.
- Early Chest Compressions: Start chest compressions as soon as possible. Delaying compressions reduces the chances of survival. Begin with a compression rate of 100-120 compressions per minute.
- Adequate Compression Depth: Compress the chest at least 2 inches (5 cm) for adults. Ensure that the chest fully recoils between compressions. Inadequate depth compromises blood flow.
- Allowing Full Chest Recoil: Allow the chest to fully recoil between compressions. Incomplete chest recoil reduces blood flow and the effectiveness of compressions.
- Minimizing Interruptions: Minimize interruptions in chest compressions. Every second counts, and prolonged pauses significantly impacts survival rates.
- Effective Ventilations: If providing rescue breaths, ensure an effective seal over the victim's mouth and nose. Deliver each breath over 1 second, with enough volume to make the chest rise visibly.
- Maintaining a Proper Compression-to-Ventilation Ratio: Follow the recommended compression-to-ventilation ratio. For adults, it is 30 compressions to 2 breaths. For hands-only CPR, continuous compressions without interruptions are often recommended.
- Avoiding Excessive Ventilations: Avoid over-ventilating the victim. Too much emphasis on rescue breaths leads to delays in chest compressions, which are the priority.
- Team Coordination (if applicable): In a healthcare setting with a team of providers, effective communication and coordination are essential. Assign roles and switch roles to prevent fatigue and maintain quality CPR.
- Using Feedback Devices (if available): If available, use CPR feedback devices that provide real-time information on compression depth, rate, and recoil. These tools helps optimize performance.
Adult Chain of Survival - IHCA (In-Hospital Cardiac Arrest)
In-hospital cardiac arrest (IHCA) demands a swift and coordinated response to maximize the chances of survival. The Adult Chain of Survival for IHCA outlines a systematic approach within healthcare facilities. It begins with the rapid recognition of cardiac arrest, prompting an immediate activation of the hospital's emergency response system. Subsequently, the focus shifts to the delivery of high-quality CPR, minimizing interruptions in chest compressions.
The chain includes the potential use of defibrillation to restore a normal heart rhythm and progresses to advanced life support administered by healthcare professionals. Post-cardiac arrest care, including targeted temperature management, forms the final link in this critical chain, striving to optimize the patient's recovery prospects.
Adult Chain of Survival - OHCA (Out-of-Hospital Cardiac Arrest)
Out-of-hospital cardiac arrest (OHCA) presents unique challenges, necessitating a community-oriented approach. The Adult Chain of Survival for OHCA emphasizes early recognition and activation of emergency services. Immediate high-quality CPR is crucial, focusing on chest compressions to maintain blood circulation.
Rapid defibrillation with an automated external defibrillator (AED) by bystanders or emergency responders is a pivotal step. Advanced life support follows, delivered by healthcare professionals upon arrival. The chain concludes with post-cardiac arrest care, recognizing the importance of ongoing medical attention beyond the initial resuscitation efforts.
Pediatric Chain of Survival
Cardiac emergencies in pediatric patients demand specialized care, and the Pediatric Chain of Survival outlines a sequence tailored to their unique needs. Early recognition of distress and activation of emergency services are paramount.
The chain prioritizes immediate high-quality CPR, adjusted to the size and age of the child. Rapid defibrillation is crucial in the presence of a shockable rhythm. Advanced life support, administered by trained healthcare providers, follows. The chain culminates in post-cardiac arrest care, recognizing the significance of ongoing medical attention and support for pediatric patients on their journey to recovery.
