CAB rather than ABC

The 2010 ILCOR resuscitation guidelines were published today. Key changes and continued points of emphasis from the 2005 BLS Guidelines include the following:

  • Sequence change to chest compressions before rescue breaths (CAB rather than ABC)
  • Immediate recognition of sudden cardiac arrest based on assessing unresponsiveness and absence of normal breathing (ie, the victim is not breathing or only gasping)
  • “Look, Listen, and Feel” removed from the BLS algorithm
  • Encouraging Hands-Only (chest compression only) CPR (ie, continuous chest compression over the middle of the chest) for the untrained lay-rescuer
  • Health care providers continue effective chest compressions/CPR until return of spontaneous circulation (ROSC) or termination of resuscitative efforts
  • Increased focus on methods to ensure that high-quality CPR (compressions of adequate rate and depth, allowing full chest recoil between compressions, minimizing interruptions in chest compressions and avoiding excessive ventilation) is performed
  • Continued de-emphasis on pulse check for health care providers
  • A simplified adult BLS algorithm is introduced with the revised traditional algorithm
  • Recommendation of a simultaneous, choreographed approach for chest compressions, airway management, rescue breathing, rhythm detection, and shocks (if appropriate) by an integrated team of highly-trained rescuers in appropriate settings
