How CPR Works

How CPR Works

Our body comprises different type of system each catering to the various need of our body. Circulatory system and respiratory system is one of them and are very vital for our survival. In CPR both of these plays an important role. When we breathe the air rich in oxygen reaches the lungs where hemoglobin present in RBC (red blood cells) binds itself with oxygen molecule and is transferred to different cells and organs by arteries and capillaries.

When someone suffers electrocution, severe trauma, fits, snake bite, severe nosebleed resulting in heavy blood loss and experience the cardiac arrest our heart changes its beating pattern and changes to ventricular fibrillation and stops beating altogether. This results in cessation or very little supply of oxygen to different parts of our body and kills the tissue and organ. By starting CPR we try to resuscitate (revive) the cardio (heart) pulmonary (lungs) function. It's not sure whether we can save the life of casualty but surely we can improve the chances by 40% if CPR is administered within 4 minutes of cardiac arrest and defibrillation is provided within 10 minutes.

Invented in 1960, CPR is a simple but effective procedure that allows almost anyone to sustain life in the first critical minutes of cardiac arrest. CPR provides oxygenated blood to the brain and the heart long enough to keep vital organs alive until emergency equipment arrives.

To make learning CPR easier, a system was devised that makes remembering it as simple as
