The Evolution of CPR

  Many of our customers have taken CPR courses before, and they often wonder why they are required to re-certify every two years. One reason being that the majority of us simply do not use the skill that often, and it is easy to forget the exact protocol. It never hurts to have a refresher. But, the main reason is that the American Heart Association along with other groups are routinely analyzing CPR data and survey results. Often, this leads to slight changes in technique in an attempt to make the use of CPR more effective.


    If you have taken an AHA CPR course before, then the main change you will notice is in the sequence. Before, you probably leaned that the correct sequence was ABC (A: open the airway, B: give breaths, and C: compressions). However, now the sequence has been changed to CAB. The reason behind this is due the fact that research has concluded compressions are the most effective when given as early as possible.

    Additional research indicates that compressions alone may be the most effective mechanism in CPR. Often, in the “layman” CPR classes, we stress the benefits of hands-only CPR. Even if you think you know it perfectly, it’s easy to lose yourself in an emergency situation. If you forget the exact ratio, or are not immediately comfortable with mouth-to-mouth, then it’s best to go ahead put your hands in the middle of the chest, and “start pumping hard and fast.”  This way, by jumping in with compressions, you are automatically having a positive effect on the victim’s survival chances.


    Far too often, people who know CPR freeze and panic. This change in the sequence is not only more effective, but it is an effort to get people to respond, and for them to realize that their actions can only help. Attempting to do something is always better than regretting that you stood by and did nothing.
