Cardiopulmonary resuscitation (CPR) can save lives, but in a cardiac emergency, even trained bystanders may hesitate to perform CPR.  One potential reason, researchers say, is mouth-to-mouth resuscitation.  Fears of disease transmission or simply the added complexity of combining rescue breathing with chest compressions may deter people from giving CPR.  Fortunately, research has shown that mouth-to-mouth resuscitation may not be as important in CPR as previously thought.  In fact, under some circumstances, traditional CPR with mouth-to-mouth resuscitation may actually decrease the survival rate for victims of cardiac arrest. The best way to learn all about the information discussed int this article is to receive your CPR Certification in Redwood City.
The American Heart Association (AHA) recommends at least 100 chest compressions per minute, with two rescue breaths given after every 30 compressions.  This is still the preferred CPR method for medical personnel and others who are experienced at administering CPR in Redwood City by taking a CPR Course.  By taking over circulation and respiration, the combination of chest compressions and rescue breathing helps to deliver oxygen to the lungs and moves oxygen-carrying blood through the bloodstream.
Since 2010, however, the AHA has recommended a simplified version of CPR, hands-only CPR, for bystanders who do not have specialized CPR training or whose training is limited.  As the name suggests, hands-only CPR (also called compression-only CPR or cardiocerebral resuscitation) eliminates rescue breathing, concentrating on the delivery of chest compressions.  The recommended number of chest compressions remains the same in this method.
The AHA’s recommendation is based on a growing number of scientific studies which show increased survival rates using the hands-only method, especially when the person performing CPR is instructed by a 911 dispatcher.  For example, a study published in the New England Journal of Medicine in 2010 showed a 9% increase in the survival rate of people suffering from cardiac arrest when the hands-only method was used.  Even more encouragingly, a 2012 Japanese study showed that cardiac arrest sufferers were 33% more likely to survive with normal brain function if hands-only CPR and a defibrillator were used together.  The technique works because some oxygen remains in the bloodstream after someone suffers cardiac arrest, and the compressions help to distribute the oxygen to bodily tissues.
Despite the increased survival rate, there are some circumstances in which hands-only CPR should not be used.  Children suffering from cardiac arrest still require rescue breathing to enhance their survival chances.  If there is an obvious cause for heart stoppage other than cardiac arrest, such as suffocation or drowning, traditional CPR should be used.  Finally, because no fresh oxygen is delivered in hands-only CPR, mouth-to-mouth resuscitation should still be used if the rescuer does not know how long the victim has been in cardiac arrest, or if professional rescuers cannot respond quickly to take over and transport the victim to a hospital.  Some studies have indicated that if an ambulance is more than 15 minutes away, traditional CPR is more likely to save lives.  However, whenever someone’s heart stops beating, any CPR method is better than no CPR and that is why you should take CPR Course in Redwood City.
Although hands-only CPR should not be used in every situation, it can make a significant difference in the survival of victims of cardiac arrest.  Hard, fast chest compressions without a pause for mouth-to-mouth resuscitation can save lives.

CPR and First Aid 2010 AHA Guidelines

Redwood City, Palo Alto, Menlo Park CPR Classes

In 2010, the American Heart Association compiled its most recent set of guidelines regarding advancements and recommendations for cardiopulmonary resuscitation, CPR, and Emergency Cardiovascular Care, ECC. These guidelines were published in the organization’s online journal, Circulation. This set of guidelines commemorated the 50th Anniversary of CPR and provided a well researched assessment of current practices in both CPR and first aid.

With regard to CPR, the most pressing issue for the American Heart Association originates in its own recommendation. While the guidelines continue to promote conventional CPR, that is, CPR which is administered with intervals of chest compressions and mouth-to-mouth resuscitation, the American Heart Association advocated in 2010 for a change in sequence.

The association acknowledged that “fewer than 50% of persons in cardiac arrest receive bystander CPR” ( In an effort to increase bystander willingness to perform CPR in emergency medical situations, the association placed primary emphasis on chest compressions and use of defibrillators as an appropriate sequencing response to cardiac arrest. Studies indicated that adults in cardiac arrest responded well to this sequencing, while drowning victims and newborns responded favorably to conventional sequencing CPR, which includes intervals of mouth-to-mouth resuscitation following every thirty chest compressions. These studies prompted the association to promote retraining of CPR across the spectrum of healthcare professionals and volunteers.

Additionally, the association recognized the importance of both the rate and the depth of chest compressions. Ideally, chest compressions should occur at a rate of thirty compressions in approximately eighteen seconds. Each compression should occur at a depth of two inches.  Previously, a chest compression depth of one and a half inches was considered satisfactory.

Other recommendations made by the association include more frequent training than the usual two-year interval for recertification and further examination of therapeutic hypothermia as an effective treatment for post cardiac arrest. To minimize interruptions during the administration of chest compressions, the association recommended the elimination of checking for a pulse during the emergency response sequence. With regard to first aid, the areas of interest in the guidelines were much less conclusive. Topics of continued interest were noted; however, the association remained undecided on any further recommendations due to inconclusive study results.

Topics included in the 2010 guidelines with regard to first aid include anaphylaxes, the administration of aspirin for chest pains, hands only CPR, advocacy of the “recovery” position, use of tourniquets, spinal stabilization, snake bites, and frostbite. The association added jellyfish stings to this list of first aid concerns, and also acknowledged the use of oral fluid replacement, particularly in drinks containing electrolytes, for dehydration.

The American Heart Association’s 2010 Guidelines are a two-part report; the first part includes an executive summary that highlights achievements and pinpoints challenges in both CPR and first aid. The second part includes evidence evaluation and management of conflicts of interest. Despite the association’s recommendations for changes, particularly with regard to the administration of CPR to cardiac arrest victims, the American Heart Association continues to acknowledge CPR, even in its conventional form, as a vital lifesaving skill in the event of medical emergencies.
