How many compressions should be given per minute during CPR?

• A. 50-70 compressions
• B. 80-100 compressions
• C. 100-120 compressions
• D. 120-150 compressions

Answer: (C)

During CPR, the recommended guideline for the number of chest compressions per minute is 100-120. This rate is crucial for effectively circulating blood and oxygen throughout the body, particularly during cardiac arrest when the heart is not pumping effectively. Research has shown that compressions at this rate support better outcomes for victims by maintaining adequate blood flow to vital organs, especially the brain, which is highly sensitive to oxygen deprivation.

Maintaining this rate helps ensure that compressions remain consistent and effective. It's also important to ensure that compressions are hard and fast, at a depth of about 2 inches for adults, while allowing for complete chest recoil between compressions. This approach maximizes the volume of blood that is pumped, contributing significantly to the patient's chance of survival until professional help arrives.

Choosing a rate outside of the 100-120 range can compromise the efficiency of CPR, so adhering to this guideline is vital for effective resuscitation efforts.
