CPR for adults
💡 What You Need to Know
- Life-Saving Intervention: Cardiopulmonary Resuscitation (CPR) is an emergency procedure performed when the heart stops beating.
- Purpose: It combines chest compressions and artificial ventilation to manually pump blood to the brain and other vital organs until medical help arrives or the heart restarts.
- Time-Sensitive: Immediate CPR can double or triple a person's chance of survival from cardiac arrest.
- Cardiac Arrest: This occurs when the heart suddenly stops pumping blood effectively, leading to loss of consciousness and cessation of breathing.
🤒 Associated Symptoms
- Unresponsiveness: The individual does not respond to verbal commands or gentle shaking.
- No Breathing or Abnormal Breathing: The person is not breathing, or is only gasping (agonal breathing), which is not effective.
- Absence of Pulse: No palpable pulse can be found in major arteries (e.g., carotid artery in the neck).
- Sudden Collapse: Often, the person collapses suddenly without warning.
- Loss of Consciousness: The individual is unconscious and cannot be roused.
🛡 Crucial Precautions
- Scene Safety First: Always ensure the environment is safe for both the rescuer and the patient before approaching.
- Personal Protective Equipment (PPE): Use barrier devices (e.g., pocket mask) for ventilations if available, to prevent direct contact with bodily fluids.
- Proper Hand Placement: Ensure correct hand position (center of the chest, lower half of the sternum) to maximize effectiveness and minimize injury.
- Avoid Excessive Force: While compressions should be firm and deep, avoid unnecessary roughness that could cause additional trauma.
- Confirm Need for CPR: Rapidly assess for unresponsiveness and absence of normal breathing/pulse before initiating compressions.
🍽 Dietary Directions & Restrictions
- Airway Clearance: Ensure the patient's airway is clear of any food, fluids, or foreign objects before attempting ventilations to prevent aspiration.
- Potential for Regurgitation: Be aware that regurgitation of stomach contents can occur during CPR; turn the head to the side if vomiting occurs to prevent aspiration.
- Post-Resuscitation NPO: Following successful resuscitation, the patient will typically be kept 'nil per os' (NPO) until a full medical evaluation and airway protection assessment are completed.
- Hydration Status: While not directly related to CPR performance, underlying dehydration or electrolyte imbalances can contribute to cardiac events, highlighting the importance of overall patient health.
⚠️ Attendant Guidelines
- Call Emergency Services: Immediately call 911 (or your local emergency number) and activate the emergency response system.
- Initiate Compressions Promptly: Begin chest compressions without delay if the person is unresponsive and not breathing normally.
- Locate AED: If an Automated External Defibrillator (AED) is available, retrieve it and apply it as soon as possible.
- Continuous High-Quality CPR: Continue compressions and ventilations until emergency medical services (EMS) arrive, an AED is ready for use, or the person shows signs of life.
- Minimize Interruptions: Limit pauses in chest compressions to less than 10 seconds.
🩺 Physician's Perspective
- Early Recognition is Key: Prompt identification of cardiac arrest and immediate initiation of CPR are critical determinants of patient outcome.
- High-Quality Compressions: Focus on adequate depth (2-2.4 inches or 5-6 cm), rate (100-120/min), and full chest recoil between compressions.
- Defibrillation Importance: For shockable rhythms (Ventricular Fibrillation/Pulseless Ventricular Tachycardia), early defibrillation significantly increases survival rates.
- Post-Resuscitation Care: Comprehensive post-cardiac arrest care, including targeted temperature management and hemodynamic support, is vital for neurological recovery.
- Training and Certification: Encourage all healthcare providers and the public to obtain and maintain current CPR certification.
🎓 Academic & Nursing Corner
- Systematic Assessment: Utilize the 'CAB' approach (Circulation, Airway, Breathing) for rapid assessment in an emergency.
- Team Dynamics: Understand roles and responsibilities within a resuscitation team to ensure efficient and coordinated care.
- Ventilation Technique: Practice effective bag-mask ventilation or mouth-to-mouth techniques, ensuring a good seal and visible chest rise.
- Documentation: Accurately record the time CPR was initiated, interventions performed, medications administered, and patient response.
- Ethical Considerations: Be aware of advanced directives (e.g., DNR orders) and ethical considerations surrounding resuscitation efforts.
🔬 Clinical Reference Index
- Compression Depth (Adult): At least 2 inches (5 cm) but no more than 2.4 inches (6 cm).
- Compression Rate (Adult): 100 to 120 compressions per minute.
- Compression-to-Ventilation Ratio (Adult, Single Rescuer): 30 compressions to 2 breaths.
- Compression-to-Ventilation Ratio (Adult, Healthcare Provider, Advanced Airway): Continuous compressions (100-120/min) with 1 breath every 6 seconds (10 breaths/min) asynchronously.
- Chest Recoil: Allow complete chest recoil after each compression to ensure adequate cardiac filling.
- AED Use: Follow AED prompts; deliver a shock if advised, then immediately resume CPR.
