What is the correct way to perform CPR on an adult?

Performing CPR on an adult involves specific techniques that are critical for maintaining blood flow and maximizing chances of survival in a cardiac emergency. The correct method emphasizes pushing hard and fast in the center of the chest at a rate of 100-120 compressions per minute. This guideline represents best practices for CPR, as compressions performed within this rate have been shown to be most effective in circulating blood and oxygen to vital organs, including the brain.

The technique includes compressing the chest to a depth of at least 2 inches and allowing full recoil between compressions. This action helps create a vacuum that aids in the return of blood to the heart, which is vital for restoring the heart's function.

While other options contain elements relevant to CPR, they are not aligned with current recommendations. For instance, compressing at a rate lower than 100 compressions per minute reduces the effectiveness of the maneuver. Additionally, pushing softly or slowly compromises the strength needed for adequate blood circulation. Furthermore, the frequency of rescue breaths (5 after every 30 compressions) isn't the current standard in hands-only CPR situations, as the emphasis is placed on continuous chest compressions without interruptions for breaths in many cases. Therefore, the guidelines that promote pushing hard and fast at the
