What is the purpose of CPR?

• A. To maintain blood circulation and oxygenation until further medical help arrives
• B. To alleviate pain and discomfort during emergency situations
• C. To assist in the recovery of unconscious patients
• D. To provide immediate medication for heart conditions

Answer: (A)

The purpose of CPR, or cardiopulmonary resuscitation, is primarily to maintain blood circulation and oxygenation in a person who has stopped breathing or whose heart has stopped beating. When a person experiences cardiac arrest, their heart is unable to pump blood effectively, which means that vital organs, including the brain, are deprived of oxygen. This can lead to irreversible brain damage or death within a matter of minutes if blood flow is not restored.

CPR involves a combination of chest compressions and rescue breaths (if performed in the full sequence) to artificially maintain blood flow and provide oxygen to the lungs, effectively keeping the victim alive until professional medical help, such as EMTs or paramedics, arrives on the scene. This immediate response can significantly increase the chances of survival and reduce the risk of long-term damage.

Other options relating to alleviating pain or providing medication do not capture the critical lifesaving function of CPR itself. While alleviating discomfort may be part of general emergency care, the primary goal of CPR is to sustain life-supporting blood circulation and gas exchange.
