CARDIAC ARREST
  A cardiac arrest occurs when the heart stops beating. It may stop altogether or the rhythm may become chaotic preventing it from pumping effectively. Without blood circulation, brain damage begins after about four minutes and death usually occurs after about ten minutes. Cardiac arrest may occur as a result of a heart attack, but everyone who suffers a heart attack does not have a cardiac arrest or need CPR.

Other common causes of cardiac arrest are:

  • Electric shock
  • Drowning
  • Drug overdose
  • Suffocation
  • Trauma
