The 2010 AHA Guidelines were recently released in October. This is an exciting time for all healthcare professionals, professional rescuers, and the lay rescuer. There are some significant changes in the AHA guidelines. It is important to begin your review as soon as possible to understand the recommendations. As an authorized provider of CPR and ECC courses, We thought it would be beneficial to highlight key areas of the recommendations. In this multipart series, we will guide you through the new recommendations and provide the rationale for the changes.
The 2010 AHA Guidelines for CPR and ECC are based on an international evidence evaluation process that involved hundreds of international resuscitation scientists and experts who evaluated, discussed, and debated thousands of peer-reviewed publications.
MAJOR ISSUES AFFECTING ALL RESCUERS
- There is continued emphasis on high-quality CPR
- Compression rate of at least 100/min
- Compression depth of at least 2 inches in adults and at least 1/3 of the anterior-posterior diameter of the chest in children and adults
- Allow complete recoil after each compression
- Minimizing interruption of compressions
- Avoid excessive ventilation
- Ratio of compression to ventilation 30:2 for 1 rescuer CPR
- Breaths delivered over 1 second
- Once an advanced airway is in place continuous compressions should be performed (at least 100/min) and 1 rescue breath every 6 to 8 seconds.
CHANGE FROM A-B-C TO C-A-B
The 2010 AHA Guidelines for CPR and ECC recommend a change in the BLS sequence of steps from A-B-C (Airway, Breathing, Chest compressions) to C-A-B (Chest compressions, Airway, Breathing) for adults, children, and infants.
Rationale:
- Highest survival rates from cardiac arrest are reported among patients of all ages who have a witnessed arrest and an initial rhythm of ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). In these patients, the critical initial elements of BLS are chest compressions and early defibrillation.
- A-B-C sequence, chest compressions are often delayed while the responder opens the airway to give mouth-to-mouth breaths, retrieves a barrier device, or gathers and assembles ventilation equipment. By changing the sequence to C-A-B, chest compressions will be initiated sooner and the delay in ventilation should be minimal.
- Most victims of out-of-hospital cardiac arrest do not receive any bystander CPR. One reason may be the A-B-C sequence that starts with opening the airway and delivering breaths may deter people from starting CPR. Starting with chest compressions might encourage more rescuers to begin CPR.
