Approximately 350,000 people in the United States experience out-of-hospital cardiac arrest annually, with 60% to 80% of these individuals not making it to the hospital.[1] Approximately 10.4% of patients who experience cardiac arrest outside the hospital survive their initial hospital admission, with only 8.2% achieving good neurological and functional status.[2] In-hospital cardiac arrest occurs in around 1.2% of adult patients in United States hospitals. Of these patients, 25.8% are discharged alive, and 82% of those who are discharged have good neurological outcomes. The key components for consistently improving patient outcomes, both inside and outside hospitals, include guideline-based management, training in layperson cardiopulmonary resuscitation (CPR), and the design of a chain of survival system.[3] The American Heart Association (AHA) develops guidelines for CPR that provide evidence-based recommendations on managing cardiovascular emergencies and cardiac arrest. These guidelines date back to 1966 and have been periodically updated by the AHA based on emerging evidence and trials.[4] Notable improvements have been made over the years since the initial CPR guidelines were published. Significant improvements have been observed in outcomes for in-hospital cardiac arrest, whereas advancements in the emergency medical services (EMS) response to out-of-hospital cardiac arrest have lagged behind considerably.[5] Designing clinical trials for resuscitation poses ethical challenges, as randomization often occurs before informed consent can be obtained, necessitating a balance between risk, randomization, and ethical requirements for informed consent in medical research.[6] Some studies use at-risk community consultation as an alternative to informed consent before randomization, as out-of-hospital cardiac arrest is largely an unpredictable event. United States federal regulations now mandate community consultation and public disclosure before initiating clinical trials in emergency situations.[7] Strong evidence in resuscitation research is lacking due to these challenges. Many of the AHA Advanced Cardiac Life Support (ACLS) guidelines are based on expert opinion, prospective and retrospective observational data, and animal studies.[8]

Many of the AHA Advanced Cardiac Life Support (ACLS) guidelines are based on expert opinion, prospective and retrospective observational data, and animal studies.[8] The current consensus focuses on early recognition, high-quality CPR, and defibrillation of shockable rhythms. Adequate ACLS delivery relies heavily on basic life support (BLS) principles, with high-quality chest compressions being the cornerstone of neurologically intact survival. High-quality chest compressions are performed at the correct rate and depth, with complete recoil and minimal interruption. The adequate delivery of resuscitation, the education of the lay public and resuscitation providers, and the establishment of a well-functioning chain of survival are critical for improving resuscitation outcomes.[9]

The ACLS guidelines developed by the AHA aim to improve the management of severe cardiovascular emergencies, including cardiac arrest, stroke, and acute coronary syndromes. These guidelines encompass advanced medical procedures, medications, and techniques to stabilize patients and improve survival rates. Key components of ACLS include high-quality CPR, arrhythmia management, defibrillation, advanced airway placement, and IV medication administration. The structured algorithms provided in ACLS training enable healthcare professionals to make rapid, evidence-based decisions during critical situations, ensuring each step aims to optimize patient outcomes. The successful implementation of ACLS protocols relies heavily on the collaboration of an interprofessional team. Emergency medicine clinicians, paramedics, pharmacists, and other healthcare providers must collaborate to provide timely and coordinated care. Each team member brings unique expertise and skills, contributing to a comprehensive approach to patient care. This collaborative effort, supported by clear communication and shared decision-making, enhances patient safety, reduces errors, and ultimately improves patient outcomes. Effective interprofessional communication is paramount in ACLS administration, allowing for seamless information exchange and collaborative decision-making among team members. Regular training and simulations help reinforce these communication skills and ensure that all team members are familiar with the latest ACLS protocols and procedures. By fostering a culture of continuous learning and mutual respect, healthcare teams can better coordinate care, address any challenges that arise during emergencies, and provide high-quality, patient-centered care. This team-based approach not only improves patient outcomes but also enhances the overall performance and efficiency of the healthcare system in managing cardiovascular emergencies.
