Cardiac arrest can be caused by a malfunction of the heart’s electrical system, a heart attack, drug overdose, drowning or other causes. The lack of oxygenated blood can cause brain damage or death in 10 minutes or less. CPR can keep blood flowing to the brain and other organs, doubling or tripling a person’s chance of survival.
