What is the proper technique for performing chest compressions during CPR? Use upper body weight to compress the chest about one inch, at a rate of 60 compressions per minute
Use all the force of your arm strength to compress the chest about two inches, at a rate of 60 compressions per minute
Use upper body weight to compress the chest about two inches, at a rate of 100 compressions per minute
Use all the force of your arm strength to compress the chest about one inch, at a rate of 100 compressions per minute

Use upper body weight to compress the chest about two inches, at a rate of 100 compressions per minute.

Explanation:

"CPR" stands for "Cardiopulmonary resuscitation." This is a technique that is being used in order to save the lives of people in emergency situations. This is only done when the person has "no pulse." A CPR allows the oxygenated blood to be delivered to the body's vital organs, including the brain, which then prevents the person from dying.

In order to "restore the blood circulation," you have to use your upper body weight in compressing the person's chest. It should be at least 5 cm or 2 inches, but not greater than 6 cm. This assures quality chest compressions. The rate should be at 100 to 200 compressions. It should be done in an uninterrupted fashion.
