Third, fatigue during CPR is a major factor. Given that mandatory retraining occurs usually on an annual or biannual basis, it becomes difficult to deliver compressions accurately. Performing CPR is a task that is seldom practiced in real life by the lay public even professional rescuers perform CPR at a much lower frequency than other procedures, such as measuring blood pressure or gaining intravenous access. Second, the training must be simple enough to acquire quickly and retain. It is thought that late middle school children may be the minimum age to learn and deliver CPR.

First, the rescuer must be of sufficient size and weight in order to generate adequate compressions. There are many challenges to achieving continuous, high-quality compressions. This “duty cycle” is repeated at a rate faster than 100 times per minute but slower than 120 times per minute, interrupted every 30 compressions to deliver a small volume of air to ventilate the lungs. The rescuer returns back to an upright position, releasing all pressure off the chest. Historically, chest compressions have been delivered manually, with the rescuer kneeling upright next to the victim, using two outstretched arms placed over the sternum, and bending at the hips to create a downward force. In subsequent updates to the AHA CPR guidelines the emphasis on high-quality compressions continued.

In 2005, the American Heart Association recommended that the management of cardiac arrest revolved around minimally interrupted chest compressions of adequate depth and sufficient rate to adequate blood pressure in the cardiovascular system, while ensuring that full recoil off the chest was achieved to allow blood flow through the coronary arteries. It became increasingly obvious that effective BLS in the form of high quality chest compressions was crucial in resuscitation efforts. However, in one study after another it became clear that these more complex and complicated techniques were not improving survival rates. It was thought that medications and ALS procedures such as intubation would help to increase survival rates.

Peter Safar first described the modern technique of pushing on the chest to create blood flow, researchers have worked to optimize manual compression depth and rate while trainers have trained millions of people worldwide in CPR.Īlong with automated external defibrillators and basic airway management, CPR is considered a fundamental component of BLS in cardiac resuscitation.įrom the 1970s to the late 90s, much attention was given to ALS. Survival from sudden cardiac arrest is zero percent if external chest compressions are not performed.
