CPR changing from A-B-C to C-A-B
In 2010, the governing body for regulations to CPR, released the 2010 AHA guidelines for CPR and ECC. The most drastic change in those guidelines is the change from the basic method of rescue developed over a half century ago, of Airway, Breathing, Chest Compressions / Circulations, to chest compressions, airway, breathing. This change has come about due to several studies.
Since 2005, the focus has been to increase the quality of chest compressions and to minimize the pauses between intervals of chest compressions. Studies until then were showing that the quality of chest compressions, with depth, speed and recoil were poor. Another focus was the continuing issue of compression only CPR. This was the main focus in the 2005 major changes to the Guidelines for CPR and ECC.
2010 yielded more changes and more focus on chest compressions for adults and paediatric patients (children, and infants). The focus has continued on the importance of chest compressions and not only the delay between intervals but the delay to begin chest compressions. Studies show that with the time for lay rescuers to open an airway and attempt to ventilate involves too much time and that time is taken away from the rescuer moving towards doing chest compressions and applying an AED which dramatically increases survival rates. Studies show that the sooner chest compressions and AED are administered to a patient the higher the chance of survival.
New guidelines are trying to incorporate chest compressions prior to airway and breathing which is why the popular “A-B-C” method is changing towards a new “C-A-B” method. One obvious concern about this change is how students and lay person will adapt away from such a simple acronym.
