For effective CPR, what is the core principle to be maintained for compressions?

For effective CPR, maintaining consistency in compressions and adhering to the correct rate is crucial. This principle ensures that the heart can be adequately stimulated to circulate blood and oxygen to vital organs, which is essential during cardiac arrest. The recommended compression rate is 100 to 120 compressions per minute, and compressions should be delivered with sufficient force to create adequate blood flow while allowing for complete chest recoil between compressions.

Consistent and correctly timed compressions not only enhance the likelihood of a positive outcome but also help to keep the rhythm and pacing of the CPR process uniform, making it easier for the rescuer and any assisting personnel. This rhythm helps to create a more effective and efficient resuscitation effort, ultimately improving the chances of survival for the individual in cardiac arrest.

The other options do not adequately emphasize the importance of both the rate and consistency of compressions, which are vital for effective CPR.
