IT TAKES JUST 4 MINUTES for the brain to begin to deteriorate when someone stops breathing.
During cardiac arrest, a person’s chances of recovery decline by 10 % every minute that emergency care is delayed. Cardiopulmonary resuscitation saves lives. With proper training, CPR is easy to learn and use ,and it can mean the difference between life and death in an emergency.

CPR, or cardiopulmonary resuscitation, is an emergency life-saving procedure used on someone who is not breathing and has no pulse. A trained rescuer fills the victim’s lungs with air and administers chest compression to pump blood from the heart through the body. Thousands of lives are saved each year through the timely use of CPR. CPR is a procedure that must be properly and promptly performed until emergency medical help arrives.
In sudden cardiac arrest, the heart goes from a normal heartbeat to a quivering rhythm called ventricular fibrillation (VF). This happens in approximately 2/3rds of all cardiac arrests. VF is fatal unless an electric shock called defibrillator can be given. CPR does not stop VF, but CPR extends the window of time in which defibrillator can be effective.
CPR provides a trickle of oxygenated blood to the brain and heart and keeps these organs alive until defibrillator can shock the heart into a normal rhythm.
WHAT IS HEART ATTACK?
A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. Injury to the heart muscle causes chest pain and pressure. If blood flow is not restored within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to die for 6-8 hours at which time the heart attack usually is “complete.” The dead heart muscle is replaced by scar tissue. Approximately one million Americans suffer a heart attack each year.
What are the symptoms of a heart attack?
Although chest pain or pressure is the most common symptom of a heart attack, heart attack victims may experience a diversity of symptoms that include:
- Pain, fullness, and/or squeezing sensation of the chest
- Jaw pain, toothache, headache
- Shortness of breath
- Nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort
- Heartburn and/or indigestion
- Arm pain (more commonly the left arm, but may be either arm)
- Upper back pain
- General malaise (vague feeling of illness)
- No symptoms (Approximately one quarter of all heart attacks are silent, without chest pain or new symptoms. Silent heart attacks are especially common among patients with diabetes mellitus)
