Overview
Advanced cardiac life support refers to a set of guidelines used by medical providers to treat life-threatening cardiovascular conditions. These life-threatening conditions range from dangerous arrhythmias to cardiac arrest. ACLS algorithms frequently address at least five different aspects of peri-cardiac arrest care: Airway management, ventilation, CPR compressions (continued from BLS), defibrillation, and medications. Due to the seriousness of the diseases treated, the paucity of data known about most ACLS patients, and the need for multiple, rapid, simultaneous treatments, ACLS is executed as a standardized, algorithmic set of treatments. Successful ACLS treatment starts with diagnosis of the correct EKG rhythm causing the arrest. Common cardiac arrest rhythms covered by ACLS guidelines include: ventricular tachycardia, ventricular fibrillation, Pulseless Electrical Activity, andScope
ACLS algorithms include multiple, simultaneous treatment recommendations. Some ACLS providers may be required to strictly adhere to these guidelines, however physicians may generally deviate to pursue different evidence-based treatment, especially if they are addressing an underlying cause of the arrest and/or unique aspects of a patient's care. ACLS algorithms are complex but the table, below, demonstrates common aspects of ACLS care.ACLS Certification
Due to the rapidity and complexity of ACLS care, as well as the recommendation that it be performed in a standardized fashion, providers must usually hold certifications in ACLS care. Certifications may be provided by a few different, generally national, organizations but their legitimacy is ultimately determined by hospital hiring and privileging boards; that is, ACLS certification is frequently a requirement for employment as a health care provider at most hospitals. ACLS certifications usually provide education on the aforementioned aspects of ACLS care ''except'' for specialized resuscitation techniques. Specialized resuscitation techniques are not covered by ACLS certifications and their use is restricted to further specialized providers. ACLS education is based on ILCOR recommendations which are then adapted to local practices by authoritative medical organizations such as the American Red Cross, the European Resuscitation Council, or the Resuscitation Council of Asia''.'' BLS proficiency is usually a prerequisite to ACLS training; however the initial portions of an ACLS class may cover CPR. Initial training usually takes around 15 hours and includes both classroom instruction and hands-on simulation experience; passing a test, with a practical component, at the end of the course is usually the final requirement to receive certification. After receiving initial certification, providers must usually recertify every two years in a class with similar content that lasts about seven hours. Widely accepted providers of ACLS certification include, non-exclusively: American Heart Association, American Red cross, European Resuscitation Council or the Australian Resuscitation Council. Holding ACLS certification is a testament to a provider's education on ACLS guidelines. The certification does ''not'' superseded a provider's scope of practice as determined by state law or employer protocols; and does not, itself, provide anyEfficacy of ACLS
Like a medical intervention, researchers have had to ask whether ACLS is effective. Data generally demonstrates that patients have better survival outcomes (increased ROSC, increased survival to hospital discharge and/or superior neurological outcomes) when they receive ACLS; however a large study of ROC patients showed that this effect may only be if ACLS is delivered in the first six minutes of arrest. This study also found that ACLS increases survival but does not produce superior neurological outcomes. Some studies have raised concerns that ACLS education can be inconstantly or inadequately taught which can result in poor retention, leading to poor ACLS performance. One study from 1998 looked at the ACLS use of epinephrine, atropine, bicarbonate, calcium, lidocaine, and bretylium in cardiac arrests and found that these medications were not associated with higher resuscitation rates. Research on ACLS can be challenging because ACLS is a bundle of care recommendations; with each individual treatment component being profoundly consequential. There is active debate within the resuscitation research community about the value of certain interventions. Active areas of research include determining the value of vasopressors in arrests, ideal airway use and different waveforms for defibrillation.International guidelines
Stemming from the need for standardized, evidence based ACLS guidelines, an international network of academic resuscitation organizations was created. The International Liaison Committee on Resuscitation (ILCOR) is the central, international institution that regional resuscitation committees strive to contribute to and disseminate information from. The centralization of resuscitation research around ILCOR reduces redundant work internationally, allows for collaboration between experts from many regional organizations, and produces higher quality, higher powered research.International Liaison Committee on Resuscitation
ILCOR serves as a way for international resuscitation organizations to communicate and collaborate. ILCOR publishes scientific evidence reviews on resuscitation known as "Continuous Evidence Evaluation (CEE) and Consensus on Science with Treatment Recommendations (CoSTRs)". ILCOR uses 6 international task forces to review over 180 topics through a structured systematic-review process. ILCOR traditionally published updates and recommendations every five years but now conducts continuous review work. ILCOR produces international recommendations which are then adopted by regional resuscitation committees which publish guidelines. Regional guidelines can have more medicolegal bearing than ILCOR recommendations. ILCOR is composed of the following regional organizations:History
ILCOR
The International Liaison Committee on Resuscitation (ILCOR) was established 1992 to serve as a way for international resuscitation organizations to communicate and collaborate.AHA Guidelines
The ACLS guidelines were first published in 1974 by theERC Guidelines
The first version of the European Resuscitation Council (ERC) guidelines were developed in 1992. The 2000 ERC guidelines were developed in collaboration with ILCOR. 5-year updates were published from 2000 to 2015 and annual updates have been published since 2017.See also
