In what manner should chest compressions be delivered during CPR?

Delivering chest compressions during CPR is crucial for maintaining blood circulation in a victim experiencing cardiac arrest. The most effective method is to perform compressions that are hard, fast, and deep.

Compressions should be delivered at a rate of 100 to 120 compressions per minute and to a depth of at least 2 inches (5 cm) for adults. This approach helps create sufficient blood flow to vital organs, particularly the brain and heart, during the critical minutes when the heart is not pumping effectively.

The focus on hardness and depth ensures that the compressions generate enough pressure to effectively circulate blood. Fast compressions help to maintain an adequate heart rate for artificial circulation, crucial in the absence of a functioning heartbeat. This technique is endorsed by both the American Heart Association and other leading organizations, underlining its importance in improving survival rates for cardiac arrest patients.

Other options, while they may suggest various techniques, do not meet the established guidelines for effective CPR and therefore would not provide the necessary support to the victim.
