Chest compressions are a critical component of cardiopulmonary resuscitation (CPR), and performing them correctly can significantly improve the chances of survival for someone experiencing cardiac arrest. The correct method involves compressing hard and fast at a rate of 100-120 compressions per minute. The guidelines emphasize that compressions should be deep enough to create adequate blood flow and should be delivered at a quick pace to maintain circulation during the emergency situation.

The recommended depth for adults is at least 2 inches (5 cm), ensuring that the heart is effectively pumping blood. The rhythm of 100-120 compressions per minute can be facilitated by mentally keeping in time with common songs that have a similar tempo, such as 'Stayin' Alive' by the Bee Gees. This pace ensures that you are providing compressions that are both effective and within the guidelines set by organizations such as the American Heart Association and the Canadian Resuscitation Council.

In summary, choosing to perform compressions hard and fast at the recommended rate directly aligns with established CPR protocols, making it the best approach for assisting someone in cardiac arrest.
