Cardiac Arrest

May 31, 2013

Cardiac arrest occurs when your heart prevents circulating blood around the body. The most common cause of a cardiac arrest is a debilitating abnormal heart rhythm called ventricular fibrillation. It is also identified as cardiopulmonary arrest. It is different from heart attack (myocardial infarction), where blood circulation to the continuous beating of heart is interrupted.

Cerebral hypoxia or lack of oxygen supply to the brain, cause sufferers to lose awareness and stop normal respiration. Injury to the brain is likely if cardiac arrest is without treatment for more than five minutes, although new treatments such as induced hypothermia have begun to improve this time. To improve survival and nerve recovery, immediate response is critical.

Cardiac arrest is a medical emergency. In certain groups of sufferers, it is often reversible if handled early enough. When surprising cardiac arrest leads to loss of life, this is called sudden cardiac death (SCD).

Causes of Cardiac Arrest:

  • Less amounts of blood
  • Lack of oxygen
  • If the person’s body is very hot or very cold
  • Clotting of blood in the lungs or coronary arteries

Is Cardiac Arrest different from Heart Attack?

Cardiac arrest is totally different from heart attack. A cardiac arrest happens when your heart prevents pumping blood around the body. As a result you will be subconscious and will not be able to take respiration normally. Immediate cardiopulmonary resuscitation (CPR) and defibrillation is needed to have any chance of success.

Cardiopulmonary resuscitation (CPR):

Unless someone begins cardiopulmonary resuscitation (CPR), the person is affected with long lasting harm to the brain and other body parts.

CPR means:

Chest compression (pumping the heart by exterior cardiac massage), to keep the flow going until the emergency vehicle comes and Rescue breathing (inflating the respiratory system by using mouth-to-mouth resuscitation).
