CPR using chest compressions only is better than standard CPR

cpr chest compressions

A new study, published in the journal Circulation, has found that long term survival is better in patients who receive CPR with chest compressions only compared to standard CPR which is a combination of chest compression and mouth to mouth resuscitation. When a person suffers from a cardiac arrest, it has been noted that the bystanders are so intimidated by the procedure of standard CPR that they end up performing no CPR at all. It is in these circumstances that chest compression CPR has been found better than the standard CPR.

An earlier study, done in 2008, had found no short term survival differences in cardiac arrest victims who received chest compression – only CPR and those who received standard CPR.  Even the American Heart Association has preferred chest compression-only CPR in order to make the process easy for the bystanders. However these recommendations are applicable only when a patient suffers from cardiac arrest outside hospital settings and there are no trained paramedics at the site. It has also been stressed that this is applicable only for adult patients and not for pediatric patients.

For their study, the researchers looked at the data from two randomized trials done in 2010 wherein 3,200 adults suffered from cardiac arrests due to heart conditions in front of bystanders. The victims received either standard CPR or chest compression-only CPR. The long term outcome of 78 % of these patients was studied by the authors. It was observed that one year survival rate of patients who received only chest compressions was 12% compared to 10% for those who received the standard CPR. The mortality in the group who received chest compressions only was 9% lower than the group who received standard CPR. The researchers noted that the short term benefit persisted over five years. This means that chest compression-only CPR performed by the bystanders immediately after an adult suffers from a cardiac arrest due to some heart problem, stands to benefit the patient even in long term. The researchers have opined that in case of cardiac arrest with no obvious non cardiac cause, there is already some oxygen in the blood of the victim. When such a patient receives chest compressions, this oxygen is distributed to the vital organs.
