Heel-Only CPR: A Giant Step for Resuscitation?

Heel-Only CPR: A Giant Step for Resuscitation?

Research has demonstrated the benefits of “hands-only CPR” or “continuous chest compressions,” as an approach that is easily learned and likely to increase bystander intervention in cases of sudden cardiac arrest, compared with traditional CPR, which includes chest compressions plus rescue breathing.

However, anyone who has given CPR knows it can be extremely tiring. Further, its effectiveness depends on quality (e.g., rate, depth of compression, leaning).

But what would happen if instead of compressing the chest using the heels of their hands, bystanders used the heels of their feet? Would chest compressions be more effective? Would rescuers have more endurance?

Robert H. Trenkamp, Jr., MBA, of Saving Lives in Chatham County (SLICC), a member of the Sudden Cardiac Arrest Foundation Advisory Council, and Fernando J. Perez, MD, of St. Joseph/ Candler Hospital Emergency Department in Savannah GA, set out to test this theory.

They assembled a test cohort whose age distribution matched that of cardiac arrest victims, rather than traditional research subjects, such as medical residents.

“There are a lot of differences between bystanders and healthcare providers,” said Trenkamp. “Most bystanders have not been trained and they are not supervised. They rarely have immediate backup to relieve their efforts and so they have to provide chest compressions from the time of the arrest until EMS arrival. And they haven’t been told they might break ribs and if this happens they still need to continue.”

The Savannah study revealed that 49 people—each acting as his or her own control by attempting 10 minutes of manual compressions before attempting 10 minutes of heel compressions—showed that four times as many people were able to hit 10 minutes using their heels, compared with using their hands (65 percent vs. 16 percent). This was in the context of using a CPR manikin with chest stiffness that is one-third less than the average adult chest.

"Stamina gets a boost with heel compressions,” said Trenkamp. “Because one cannot use his or her total weight—just the upper body weight—when performing manual compressions, the use of heel compressions increases the percentage of the adult population that can deliver guideline-compliant chest compressions.” Many people in the age group tested cannot perform guideline-compliant chest compressions manually, he added. Some cannot get down on the floor and some have arthritis issues with their hands or wrists that interfere with performance of manual chest compressions.

SLICC has taught heel compressions to more than 10,000 laypersons in the Savannah, GA area. Its class videos are available online here

Mission & Vision

The mission of the Sudden Cardiac Arrest (SCA) Foundation is to prevent death and disability from sudden cardiac arrest. The vision of the SCA Foundation is to increase awareness about sudden cardiac arrest and influence attitudinal and behavioral changes that will reduce mortality and morbidity from SCA.
