As an ASHI Training Center, EmergiLearn can help YOU be prepared for the worst:
Sudden cardiac arrest, or SCA, can occur without warning to anyone, at any time. It is one of the leading causes of death among adults in the United States.
Sudden cardiac arrest happens when the normal electrical impulses in the heart unexpectedly become disorganized. The normally coordinated mechanical contraction of the heart muscle is lost, and a chaotic, quivering condition known as ventricular fibrillation can occur.
Blood flow to the brain and body abruptly stops. The lack of blood and oxygen to the brain causes the person to quickly lose consciousness, collapse, and stop breathing.
Brain tissue is especially sensitive to a lack of oxygen. When oxygen is cut off, brain death can occur quickly, within a matter of minutes. Without early recognition and care from a bystander, the person will not survive.
Cardiopulmonary resuscitation, or CPR, allows a bystander to restore some oxygen to the brain through a combination of chest compressions and rescue breaths.
