Statistics indicate that 70%-80% of cardiac arrest cases occur either in the home or at public places. In such cases, the person nearest at hand to the victim is often a bystander with no medical expertise such as a relative, an office colleague, or a passer-by. If those present at the scene are able to provide CPR to the victim promptly, the latter’s chances of survival are significantly increased.
This is because time is the essence when treating a cardiac arrest victim. Once the heart stops beating and blood flow stops, a person will lose consciousness within 15 seconds. Within another 30 to 60 seconds, he will stop breathing, and irreversible damage to his brain cells will follow after several minutes of oxygen deprivation.
What is CPR?
Cardiopulmonary resuscitation, commonly known as CPR, is an emergency procedure performed in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing. It is indicated in those who are unresponsive with no breathing.
What is the purpose of CPR?
CPR is unlikely to restart the heart. Its main purpose is to restore partial flow of oxygenated blood to the brain and the heart. The goal is to delay tissue death and to extend the opportunity for successful resuscitation without permanent brain damage or death. The administration of an electric shock, termed defibrillation, is usually needed to restore viable heart rhythm. CPR will succeed in inducing heart rhythm and should be continued until the patient is breathing or is declared dead.
CPR can be given in four steps (CABD):
- Chest Compressions
- Airways Maintaining
- Breathing Support
