Sten Rubertsson, M.D., Ph.D., of Uppsala University, Sweden and colleagues assessed cardiopulmonary resuscitation (CPR) in patients.
They assessed whether CPR in which chest compressions are delivered with a mechanical device would result in superior 4-hour survival in patients with out-of-hospital cardiac arrest compared to CPR with manual chest compression.
One Minute of CPR Training can Help Bystanders Save Lives in Emergencies
A new study presented at the American Heart Association's Scientific Sessions 2013 suggests that just one minute of CPR video training can help people save lives in emergency situations.

"Many factors affect the chances of survival after cardiac arrest, including early recognition of arrest, effective CPR and defibrillation, and postresuscitation care. One important link is the delivery of high-quality chest compressions to achieve restoration of spontaneous circulation. The effectiveness of manual chest compressions depends on the endurance and skills of rescuers, and manual compressions provide only approximately 30 percent of normal cardiac output. Manual CPR is also limited by prolonged hands-off time, and its quality is particularly poor when it is administered during patient transport. Mechanical chest compression devices have therefore been developed to improve CPR," according to background information in the article. "A strategy using mechanical chest compressions might improve the poor outcome in out-of-hospital cardiac arrest, but such a strategy has not been tested in large clinical trials."
This multicenter clinical trial, which included 2,589 patients with out-of-hospital cardiac arrest, was conducted between January 2008 and February 2013 in 4 Swedish, 1 British, and 1 Dutch ambulance services and their referring hospitals. Duration of follow-up was 6 months. Patients were randomized to receive chest compressions from a mechanical device combined with defibrillation during the compressions (n = 1,300) or manual CPR according to guidelines (n = 1,289). The mechanical chest compressions device had an integrated suction cup designed to deliver compressions according to resuscitation guidelines.

A study finds that in Denmark between 2001 and 2010 there was an increase in bystander CPR that was associated with an increase in survival following out-of-hospital cardiac arrest.
Four-hour survival was achieved in 307 patients (23.6 percent) with mechanical CPR and 305 (23.7 percent) with manual CPR. Among patients surviving at 6 months, 99 percent in the mechanical CPR group and 94 percent in the manual CPR group had good neurological outcomes.
"In patients with out-of-hospital cardiac arrest, mechanical chest compressions in combination with defibrillation during ongoing compressions provided no improved 4-hour survival vs. manual CPR according to guidelines. There was a good neurological outcome in the vast majority of survivors in both groups, and neurological outcomes improved over time," the authors write.

Mechanical Chest Compressions are Equally as Effective as Manual CPR: Study
The study was designed to show a better 4-hour survival in the group treated with mechanical chest compressions, and this was not achieved, said lead investigator Sten Rubertsson, MD, PhD.
