CPR can serve as a critical lifesaver when administered in time and properly for someone having a heart attack. It has been observed that bystander CPR has better results when more people are present, reported Resuscitation journal on Jan. 2, 2014. This finding has come from research aimed at identifying the factors
which are associated with good quality bystander cardiopulmonary resuscitation (BCPR).
The data for this Japanese research was collected from 553 out-of-hospital cardiac arrests (OHCAs) which were managed with BCPR in the absence of emergency medical technicians (EMT) during 2012. The quality of the BCPR administered was evaluated by EMTs at the scene and was assessed in relation to the standard recommendations for chest compressions, including proper hand positions, rates and depths. It was concluded that the presence of multiple rescuers with bystander-initiated CPR are predominantly associated with the administration of good-quality BCPR.
In a review of this research by MedPage Today it has been stated that cardiac arrest victims were more likely to be given good-quality bystander-initiated cardiopulmonary resuscitation (CPR) when multiple people assisted. It was also noted in this research that good-quality bystander CPR was not as commonly performed by a family member, by older bystanders, and in home environments.
It was also noted that neurologically favorable survival 1 year after the cardiac event did not differ significantly between those people who received good-quality versus poor-quality resuscitation. It has been reported by experts in emergency medicine that the key to survival and positive neurological outcomes for those who experience an out-of-hospital cardiac arrest is the initiation of bystander CPR. This CPR should be performed with just chest compressions, without mouth-to-mouth resuscitation. However, the authors also noted that survival among patients hit with out-of-hospital cardiac arrest remains low.
