General Concept on Basic Life Support
Heart disease continues to be a leading cause of death over years and research continues to improve how we respond to emergency situations with our life saving techniques. The Basic Life Support (BLS) is a skill that comprises of training these techniques in the form of an organized series of systematic response often referred to as ” Chain of Survival”.
When the heart pumps the blood through the lungs, the blood takes in oxygen and releases carbon dioxide in the lungs. The oxygenated blood returns to the heart where it is again pumped out to supply oxygen to all parts and vital organs of the body. When the heart stops, the blood flow stops and the person becomes unconscious. Lack of oxygen will cause permanent damage to the heart and the brain.
Brain cells can begin to die within 5 minutes of oxygen loss.
Basic Life Support helps to prevent and slow the damage until appropriate medical aid is available thereby increasing the survival chances for the person.
CPR (Cardiopulmonary Resuscitation) is a first aid technique used when a person is not breathing or if their heart has stopped. This mechanism uses chest compression and mouth to mouth breathing to artificially pump the blood through the heart for continuation of blood circulation in the vital parts of the body.
Priorities of Emergency Response
Life threatening problems are identified and dealt with FIRST. It is to be ensured that the most important steps are undertaken in a logical order and nothing is omitted. This is done using the following steps:-
Chain of Survival for Adults
Keys for BLS
- Quickly start the Chain of Survival.
- Deliver high quality chest compression to circulate oxygen to the brain and vital organs.
- Know how to use AED. Provide rescue breathing.
- Understand working as a team with other rescuers.
- Be observant if any choking is present.
