Constant compressions critical to CPR
February 06, 2009Interrupting chest compressions during resuscitation reduces the chances of heartbeat return after defibrillation. New research published in the open access journal BMC Medicine shows that for every second of a pause in compressions there is a 1% reduction in the likelihood of success.
Kenneth Gundersen from the University of Stavanger, Norway, worked with a team of researchers to quantify the effect of compression interruptions on the probability of a return of spontaneous circulation (ROSC). He said, "We analysed data from 911 interruptions and found that every second without the blood perfusion generated by chest compressions has a negative impact on the estimated probability of ROSC".
The American Heart Association's first aid guidelines were updated last year, suggesting that the 'mouth-to-mouth' component of CPR was unnecessary. This new research supports that position, in that the pause in compressions required to perform artificial respiration may reduce the patient's chances of recovering their heartbeat.
Gundersen said, "The first priority when witnessing a cardiac arrest is to make an emergency call. Beyond this our results show that performing powerful chest compressions with minimal interruptions is of utmost importance. The quality of CPR matters and everyone should practice their CPR skills at regular intervals."

CPR Current Events and CPR News RSSCardiac arrest casualties form a valuable source of donor kidneys
A pilot study of a system for harvesting kidneys from non-heart-beating donors where attempts of resuscitation after a witnessed out-of-hospital cardiac arrest have failed (uncontrolled NHBDs) resulted in 21 successful kidney transplants - a 10% increase in the transplantation rate - over 17 months.
Cooling treatment after cardiac arrest is cost-effective, Penn study shows
A brain-preserving cooling treatment called therapeutic hypothermia is a cost-effective way to improve outcomes after out-of-hospital cardiac arrest, which claims the lives of more than 300,000 people each year in the United States and leaves thousands of others neurologically devastated.
New UAB Study Finds Novice Parents Overlook Many Child-Injury Risks
University of Alabama at Birmingham (UAB) Department of Psychology researchers report that new parents identified less than half of the safety hazards in a simulated home environment, and most perceived that their children were less vulnerable to injuries than other children.
Survival rates for elderly receiving hospital CPR did not improve from 1992 to 2005
A study of elderly patients receiving CPR in the hospital shows that rates of survival did not improve from 1992 to 2005.
Hospitalized patients need better understanding of CPR and outcomes
Many hospitalized patients overestimate their chance of surviving an in-hospital cardiac arrest and do not know what CPR really involves, a University of Iowa study has shown.
Mock CPR drills in kids show many residents fail in key skills, Hopkins study reveals
Research from the Johns Hopkins Children's Center exposes alarming gaps in training hospital residents in "first response" emergency treatment of staged cardiorespiratory arrests in children, while at the same time offering a potent recipe for fixing the problem.
Doctors differ on whether hospices should follow CPR guidelines
Experts in two papers published on bmj.com today disagree on whether cardiopulmonary resuscitation (CPR) guidelines should apply to hospices.
Penn study: Chances of surviving cardiac arrest depend on where patients are treated
Efforts to fight the toll of cardiac arrest have typically focused on pre-hospital factors -- bystander CPR education and improvement, public defibrillation programs, and quicker EMS response. But new research from the University of Pennsylvania School of Medicine reveals that the hospital where patients are cared for after being resuscitated plays a key role in their chances of survival following these incidents, which takes the lives of more than 300,000 Americans each year.
Study findings help EMS respond to cardiac arrest emergencies more safely and efficiently
When cardiac arrest patients cannot successfully be resuscitated by emergency medical services in the field, lifesaving attempts to race them to a nearby hospital via ambulance often prove to be futile.
LSUHSC study finds high-dose HBO2 therapy extends survival window after cardiopulmonary arrest
A ground-breaking study by researchers at the School of Medicine at LSU Health Sciences Center New Orleans published in the August 2008 issue of Resuscitation has major implications for the #1 cause of death of Americans -- sudden cardiac arrest.
