Generally, it involves giving rhythmic compression to the chest, in order to help the heart in pumping blood to the brain. Compressions can be accompanied with artificial respiration; which can be mouth to mouth or mouth to nose.
When is CPR required?
CPR is required to be given to an unconscious person with no pulse or feeble pulse. In most cases, during a Cardiac Arrest, our heart is not able to pump blood sufficiently to the brain which results in a condition called Syncope.
Constant supply of blood to the brain is required to maintain proper level of oxygen supply. CPR can be quite helpful in avoiding tissue death.
How to Do CPR
How to check for pulse?
One can feel a person’s pulse through various regions on the patient’s body. The most common site is the Side of the wrist (radial pulse). Alternative regions are on neck besides his Adam’s apple (Carotid Pulse), below ankle (Posterior tibial) or groin (Femoral). These are the areas where the fat deposition is low and one can feel the pulse easily.
Top Techniques to Do CPR
CPR can be classified into two broad classes, one outside the hospital and the other is inside the hospital.
CPR outside the Hospital
It is done by a rescuer with minimal available sources. It is done to delay the tissue death until the help arrives.
Important Things for Rescuer to Know about CPR
First of all, it’s important to check the airway for any obstruction that may be present. It can be due to the tongue, a blood clot or some foreign particle. Loosen the clothes of patient and make him lie on a flat surface.

Tilt his / her head on lateral side so that if regurgitation takes place it does not block the airway. Now the rescuer should cross his fingers and start the compression on chest.
The compression should be in proper interval in association with artificial breathing. Ratio of compression to ventilation should be 30:2. The compression should be done on middle of the sternum. Head should lie below the level of the body so that the wind pipe is straight and ventilation is effective. Ventilation can be mouth to mouth or mouth to nose. Breath should be in such a way that there is a visible inflation of chest. And compression should be with 1-2 inches on mid-sternum.
Give 30 compressions and then 2 breaths. Rescuer should press the nostrils of patient and seal the mouth with mouth and exhale, there should be visible inflation in patient’s chest. After each compression, wait for the chest to recoil to proceed for another compression. Call for some medical help.
CPR Inside the Hospital
CPR inside the hospital is done by professionally qualified persons and is done with automated devices and Defibrillators. Automated devices are designed to provide compressions and ventilations automatically at predefined intervals. They have more advantages than the conventional CPR techniques.
Advantages of Automated devices
Force of compression is constant, while during manual CPR the force cannot be constant.
More effective than the manual one as the rescuers can feel fatigued after some time and is not able to provide proper compressions after a period of time.
Rescuer is free to examine the changes in the patient and can do some other things beneficial to the patient like calling for help, preparing for defibrillation etc.
Defibrillator is a device which is used to give electrical stimulation to heart to help it to start functioning again.
