An elderly male suffered a cardiac arrest at a meeting. Another elderly male began to perform manual CPR but quickly tired and was unable to continue. The other person present - who had recently read an interview with one of the authors of an article in the American Journal of Emergency Medicine regarding Heel Compression CPR began to perform Heel CPR. The victim's heart was restarted before the arrival of EMS.
That's the whole point of Heel CPR - when you cannot get down on the ground or you have a problem pressing hard enough on the chest to get adequate compression depth, consider an alternative: Heel CPR. Go to www.slicc.org/ClassVideo and click on the Adult CPR video.
Dr. Perez and I wrote a paper about the advantages of Heel Compression CPR. It was promptly published in the American Journal of Emergency Medicine. We wrote the article describing our research so that organizations such as the American Heart Association and the American Red Cross would have a peer-reviewed basis for considering the adoption of the technique in their Bystander course curricula.
Because 85% of cardiac arrests occur in the home - and about half are witnessed - the witness is generally about the same age as the victim. Because of the age distribution of the victims, the witness / rescuer is likely to be unable to perform CPR in the same manner as a medical student or Intern - the typical cohort in a CPR study. Many cannot get down on the floor. Many have arthritis or other afflictions of the hands or arms that reduce their ability to perform Guideline-Compliant Chest Compressions ("GC3's"). It was for this reason that we developed Heel Compression CPR.
Heel Compression CPR enables four times as many people to perform GC3's. Here's the abstract from the AJEM publication:
