Which Action Would The Nurse Take When Performing External Cardiac Compression
Performing external cardiac compression, commonly known as CPR (Cardiopulmonary Resuscitation), is a critical intervention in emergency situations where a patient’s heart has stopped beating or is experiencing cardiac arrest. The primary goal is to restore blood circulation to vital organs, especially the brain and heart, until advanced medical help arrives. Nurses, as frontline responders in many clinical and emergency settings, must be well-versed in the correct procedures and actions to take during external cardiac compression. This article provides a comprehensive overview of the steps, techniques, and considerations a nurse should follow when performing external cardiac compression, ensuring optimal patient outcomes and adherence to best practices.
Understanding the Importance of External Cardiac Compression
External cardiac compression is a lifesaving technique that involves manually compressing the chest to pump blood through the heart and circulate oxygenated blood to the brain and other vital organs. It is an essential component of CPR and is often performed in conjunction with rescue breaths, depending on the situation and current guidelines.
The importance of effective external cardiac compression cannot be overstated, as immediate action significantly increases the chances of survival and reduces the risk of permanent brain damage. Nurses, especially those in emergency, critical care, or pre-hospital settings, play a crucial role in initiating and maintaining high-quality chest compressions.
Initial Assessment and Preparation
Before initiating external cardiac compression, a nurse must perform a series of vital assessments and preparations to ensure the safety of the patient and the correctness of the intervention.
1. Verify Responsiveness and Breathing
- Shake the patient gently and ask loudly, “Are you okay?”
- Check for responsiveness by observing for movement or verbal response.
- Look for normal breathing or agonal respirations. If the patient is unresponsive and not breathing normally, immediate action is required.
2. Call for Help and Activate Emergency Response
- If alone, immediately call emergency services or activate the hospital’s emergency response system.
- Obtain or direct someone to retrieve an Automated External Defibrillator (AED) if available.
- Ensure help is on the way to assist with advanced care.
3. Ensure Scene Safety
- Confirm the environment is safe for both the patient and the responder.
- Remove any hazards that could cause further injury.
4. Prepare Equipment and Position the Patient
- Carefully position the patient on a firm, flat surface to facilitate effective compressions.
- Clear the chest area by removing clothing, jewelry, or any obstructive objects.
- Use a backboard if available, especially for patients lying on a soft surface.
Performing External Cardiac Compression
Once initial assessments are complete and help is on the way, the nurse proceeds with the core action: external cardiac compression. Proper technique and rhythm are essential for effective CPR.
1. Hand Placement and Body Positioning
- Place the heel of one hand on the center of the patient’s chest, specifically on the lower half of the sternum.
- Place the other hand on top of the first, interlocking fingers or keeping them raised to avoid pressure on the ribs.
- Keep arms straight, shoulders directly above the hands, and elbows locked.
- Use body weight to generate force rather than solely relying on arm strength.
2. Compression Technique and Depth
- Compress the chest at a depth of at least 2 inches (5 cm) for adults.
- Avoid excessive depth to prevent injury.
- Allow the chest to recoil completely between compressions to enable blood flow.
- Maintain a rate of 100 to 120 compressions per minute, roughly to the beat of the song “Stayin’ Alive” by the Bee Gees.
3. Rhythm and Continuity
- Perform continuous chest compressions without significant interruptions.
- Use a metronome or music to maintain the correct rate.
- Minimize pauses, except for necessary checks or to deliver rescue breaths if indicated.
Additional Considerations During External Cardiac Compression
Effective CPR involves more than just the mechanics of compressions. Nurses must adhere to guidelines and adapt to specific patient needs.
1. Ventilation and Compression Ratio
- For adults, current guidelines recommend continuous compressions with rescue breaths if trained and comfortable.
- If performing traditional CPR, deliver 30 compressions followed by 2 rescue breaths.
- Be mindful of the patient’s condition and whether airway management or advanced airway devices are in place.
2. Use of AED
- As early defibrillation is crucial, attach an AED as soon as it’s available.
- Follow the device prompts precisely.
- Ensure no one is touching the patient during shock delivery.
3. Monitoring and Reassessment
- Continuously monitor the patient’s responsiveness and breathing.
- Reassess every 2 minutes or after a cycle of compressions.
- Be prepared to adjust techniques based on the patient’s response.
Safety and Ethical Considerations
The nurse must prioritize safety and ethical standards during external cardiac compression.
1. Avoiding Injury
- Proper hand placement and technique minimize rib fractures or internal injuries.
- Be gentle but firm, especially in vulnerable populations such as the elderly or children.
2. Respecting Patient Autonomy and Legal Guidelines
- Follow established protocols and guidelines (e.g., American Heart Association, European Resuscitation Council).
- Document actions taken and patient response.
Post-Resuscitation Actions
Once spontaneous circulation is restored or the emergency is under control, the nurse’s role shifts to ongoing assessment and supportive care.
- Provide advanced airway management if trained.
- Monitor vital signs continuously.
- Prepare for transfer to a higher level of care.
- Communicate with the healthcare team and document all interventions.
Training and Skill Maintenance
Performing external cardiac compression effectively requires regular training and practice.
- Attend certified CPR courses periodically.
- Practice techniques on mannequins.
- Stay updated with the latest guidelines and recommendations.
Conclusion
In emergency scenarios requiring external cardiac compression, the nurse’s actions are pivotal in determining patient survival. From initial assessment and scene safety to precise hand placement, compression technique, and rhythm maintenance, each step must be performed with confidence and adherence to established protocols. Continuous education, practice, and awareness of the latest guidelines ensure that nurses are prepared to deliver high-quality CPR, ultimately saving lives and reducing the impact of cardiac arrest.
