Have you ever seen anyone’s life saved by giving CPR at the right time? It is a useful technique, when done, correctly can save lives in case of emergency. Many of us often know about the method, but are not clear about what CPR stands for? In the article, we will clearly define the abbreviation and what does each letter explain individually.

What do CPR letters stand for?

CPR means cardiopulmonary resuscitation. It is used in case of emergency to save lives. The procedure needs proper training and includes mouth to mouth respiration and chest compression. It involves the right moves and breathing techniques, which are taught during the professional training program. By this method, the patient regains his breathing, and the oxygen supply starts throughout the body. It will keep the person alive till medical help arrives. CPR effectively saves lives in case of any emergencies like heart attack, stroke, electric shocks, or even drowning.

In all these situations, the individual gets blocks breathing, and oxygen supply stops in the body, which is life-threatening. Hence with pumping in oxygen through mouth and chest compressions, the lungs start functioning, and the heartbeat normalizes. Moreover, when the oxygen can’t reach the brain for just a few minutes, it can result in permanent brain death. So, by giving CPR immediately, the heart starts pumping blood to the brain and elsewhere in the body. To understand the tern more precisely, let’s look at each of the letters individually.


Cardio, as the name, suggests refers to the heart. In an average person, it contracts and expands over 60 times per minute. It is one of our body’s major organs and starts functioning even before we open our eyes in this world. Oxygen-rich blood is pumped throughout the body through the heart. If this main organ stops working for a few minutes, the oxygen won’t reach, leading to tissues and other organs damaging. It would ultimately, in a few minutes, result in death. Therefore the organ must continue functioning correctly.

P= Pulmonary

Pulmonary refers to lungs. After heart, it is one of the major organs in our body. When we breathe, the lungs fill up the oxygen necessary for functioning. The oxygen and sugar combine to give out the fuel that we utilize to carry on daily routines. Tissues can’t store much oxygen; hence the continuous flow is necessary so that each part gets a sufficient amount.

R= Resuscitation

It means giving life to someone near to death. Once your heart stops functioning, the body deprive of oxygen. Within few minutes, the tissues and organs start dying, resulting in brain damage. It hardly takes about 5-6 minutes for this process, and after 10 minutes, recovery is impossible. CPR is given within this time. Hence, it saves life by continuing the heart to pump blood to the rest of the body.

So, what does CPR stand for is clearly defined here? As the name explains, emergency treatment results in the recovery of the heart and lungs. For professional CPR training, contact
