New CPR guide sets compression limits, scratches vasopressin

New guidelines on cardiopulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) set upper limits on chest compression rate and depth, add naloxone to the care of suspected opioid abusers, and remove vasopressin from the advanced cardiac life support (ACLS) algorithm.

The American Heart Association published its revised guidelines Oct. 15 in Circulation. The AHA released its previous guidelines in 2010.

“Everyone has a role to play in the chain of survival – from bystanders to dispatchers, emergency responders to health care providers,” Dr. Mark Creager said in a statement. “When everyone knows their role, knows CPR, and works together, we can dramatically improve cardiac arrest victims’ chances of survival,” said Dr. Creager, AHA president and director of the Heart and Vascular Center at Dartmouth-Hitchcock Medical Center, Lebanon, N.H.

The 2015 guidelines’ new recommendations include the following:

• Resuscitation pathways. The guidelines note that the resuscitation pathways are very different for patients who experience cardiac arrest present in either a hospital setting (IHCA) or out-of-hospital setting (OHCA). In OHCA, the patient depends on lay rescuers to not only recognize the situation but also call for help, initiate CPR, and, if available, administer defibrillation until emergency medical personnel arrive. However, IHCA involves prevention of cardiac arrest and smooth delivery of care in a multidisciplinary setting.

• Layperson CPR. Untrained lay rescuers should provide compression-only CPR for OHCA. Trained lay rescuers who are able to provide rescue breaths should begin CPR with compressions followed by breaths at a ratio of 30 compressions to two breaths. Compression-only CPR is easier to perform for untrained lay rescuers, the guidelines note, and survival rates are similar using CPR with or without rescue breaths in adult cardiac arrest with a cardiac etiology.

• Compression rate and depth. The new guidelines set upper limits on chest compression depth and heart rate, recommending a compression rate of 100-120 compressions per minute with a depth of at least 2 inches, not to exceed 2.4 inches in adults.

• Social media dispatching. Despite limited evidence, the guideline authors said that it may be reasonable for communities to use social media technologies to alert lay rescuers with mobile phones about nearby OHCA cases.

• Naloxone and opioid addiction. Also new to the guidelines is the recommended use of naloxone for patients with suspected or known opioid addiction by appropriately trained lay rescuers or basic life support (BLS) providers.

• CPR training. The guidelines highlight several changes to simplify health care provider training in CPR. For example, trained rescuers can simultaneously perform some tasks to reduce the time to initiate chest compressions. Likewise, in a team of trained rescuers, multiple steps such as activating the emergency response system, chest compression, ventilation, and defibrillator retrieval can be accomplished simultaneously.

• High-quality CPR. Finally, the guidelines focus on emphasizing high-quality CPR with adequate compression rate and depth, complete chest recoil, few interruptions to compressions, and appropriate ventilation.

The guidelines offer several changes to advanced cardiac life support (ACLS). The algorithm was simplified by removing vasopressin, because the authors note that “the combined use of vasopressin and epinephrine offers no advantage to using standard-dose epinephrine in cardiac arrest.”

Likewise, the guidelines note conflicting studies to support the use of lidocaine after return of spontaneous circulation (ROSC). “However, the initiation or continuation of lidocaine may be considered immediately after ROSC from VF/pulseless ventricular tachycardia cardiac arrest,” the guideline authors wrote. Finally, the guidelines highlight updates in post–cardiac arrest care, including a wider range of target temperatures, between 32° C and 36° C, to be maintained for at least 24 hours in comatose adults with ROSC after cardiac arrest. In comparison, the 2010 guidelines called for a target temperature range of 32° C to 34° C for 12-24 hours. The guidelines also detail new updates for acute coronary syndrome, pediatric BLS, pediatric ACLS, and neonatal resuscitation.

As the AHA updates its CPR guidelines, it’s also important for lay rescuers and health providers to update their own training, noted Dr. Clifton Callaway, chair of the AHA’s Emergency Cardiovascular Care (ECC) committee.

“Research shows resuscitation skills can decline within a few months after training – far before the 2-year period in which basic and advanced life support skills are currently evaluated,” cautioned Dr. Callaway, professor of emergency medicine at the University of Pittsburgh. “Frequent training with shorter intervals of basic and advanced cardiovascular life support skills may be helpful for providers who are likely to encounter a cardiac arrest to ensure the patient receives high-quality CPR,” he added.
