Cardiopulmonary resuscitation is a critical emergency procedure used during cardiac arrest to sustain blood circulation and oxygen delivery to essential organs until normal heart function can be restored. The method consists of chest compressions to simulate heartbeats and artificial respirations to maintain oxygenation. Cardiopulmonary resuscitation can be performed in 2 primary forms—conventional cardiopulmonary resuscitation, which combines compressions with ventilations, and compression-only cardiopulmonary resuscitation, recommended by the American Heart Association for untrained bystanders. High-quality cardiopulmonary resuscitation—marked by proper rate, depth, minimal interruptions, and full chest recoil—is essential for increasing the chances of survival, especially when paired with early defibrillation. This activity provides healthcare professionals with evidence-based instruction on recognizing and managing cardiac arrest using cardiopulmonary resuscitation. Participants explore American Heart Association guidelines, learn the differences between conventional and compression-only cardiopulmonary resuscitation, and understand how to deliver effective, high-quality resuscitation. The activity emphasizes timely action, proper technique, and the collaborative efforts of interprofessional teams to enhance patient outcomes in critical situations. Objectives: Identify the key components of high-quality cardiopulmonary resuscitation, including optimal compression rate, depth, and ventilation techniques. Implement American Heart Association guidelines for cardiopulmonary resuscitation during cardiac arrest scenarios. Differentiate between adult, pediatric, and infant cardiopulmonary resuscitation guidelines and appropriate modifications for each patient population. Communicate effectively with team members during resuscitation to ensure coordinated and timely interventions. Access free multiple choice questions on this topic.

Cardiopulmonary resuscitation (CPR) is a life-saving technique used during cardiac arrest to maintain blood flow and oxygenation to vital organs until spontaneous circulation can be restored. The modern approach to CPR originated from the pioneering work of several clinicians in the 1950s and has since evolved into the standard practice we follow today. In North America, the American Heart Association (AHA) issued the most widely accepted guidelines, which are published every 5 years following the International Liaison Committee on Resuscitation (ILCOR) meeting.[1] According to the Centers for Disease Control and Prevention, more than 356,000 individuals in the United States experience an out-of-hospital cardiac arrest every year. Of these cases, approximately 60% to 80% result in sudden death due to the abrupt cessation of organized cardiac function.[2] Ventricular fibrillation is the most common cause of sudden cardiac arrest in adults. Although advances in emergency cardiac care have improved survival rates, sudden cardiac arrest remains a leading cause of death worldwide. As of 2022, cardiac disease continues to be the leading cause of death in the United States.[3] Approximately 70% of out-of-hospital cardiac arrest cases occur at home, and 50% of these incidents are unwitnessed. Despite improvements in emergency medical services, overall survival rates remain low. Among adults with nontraumatic out-of-hospital cardiac arrest who receive resuscitation attempts from emergency responders, the survival rate to hospital discharge is only 10.8%. In contrast, adults who experience cardiac arrest in a hospital setting have a significantly higher survival rate, with up to 25.5% surviving to discharge.[4]

CPR can lead to various complications, both skeletal and visceral, which may impact patient outcomes. Skeletal injuries are among the most common, with rib fractures occurring in up to 70% of cases and sternal fractures in about 30% of cases, often due to prolonged or forceful chest compressions.[12] Visceral injuries include contusions and lacerations to internal organs such as the heart, lungs, liver, and pericardium. Studies have documented cardiac and pulmonary contusions in more than 50% of CPR cases, along with occurrences of hemothorax and hemopericardium.[12] Cardiac injuries may involve transmural contusions or ruptures of the right atrium or aorta. Acute lung injury, including CPR-associated lung edema, can result from aggressive compressions and poor ventilation techniques. Hemothorax and pneumothorax are also recognized complications, typically secondary to fractured ribs and lung trauma. Other potential injuries include retrosternal and mediastinal hematomas and liver lacerations, especially with mechanical CPR devices.

Improving patient-centered care, safety, outcomes, and team performance during CPR requires a comprehensive approach that includes clinical skills, ethical considerations, communication, and coordinated care systems. This approach ensures that resuscitation efforts are effective, respectful of patient preferences, and supported by well-trained, collaborative healthcare teams. High-quality CPR depends on maintaining proper compression rate and depth while minimizing interruptions. Training programs should include simulation-based exercises, leadership development, and cognitive aids to reinforce best practices and reduce errors. The AHA recommends incorporating these strategies into life support training to enhance outcomes.[17] Ethical responsibilities include respecting do-not-resuscitate orders and recognizing when CPR may be medically futile. Healthcare providers must weigh the urgency of intervention against patient preferences and prognosis. Effective communication is critical during resuscitation. To improve coordination and performance, teams should have clear roles, a designated leader, and regular debriefings. A systems-level approach, including public CPR education, access to defibrillators, and structured emergency response systems, also supports better outcomes.[18][19] Post-resuscitation care requires coordination across disciplines to manage ventilation, hemodynamics, and neurological function. Teamwork and leadership training have improved adherence to guidelines, communication, and overall CPR quality.[17] Enhancing CPR outcomes involves a multifaceted strategy combining clinical training, ethical awareness, clear communication, and integrated care systems. These elements work together to ensure timely, effective, patient-centered interventions during resuscitation efforts.
