How should chest compressions be delivered?

Delivering chest compressions effectively is critical in emergency situations, such as cardiac arrest, to maintain blood circulation. The correct approach is to perform regular, rhythmic downward thrusts at the correct pace, which is typically around 100 to 120 compressions per minute. This technique ensures that adequate blood is being pushed through the body to vital organs, particularly the brain and heart, increasing the chances of survival until professional medical help arrives.

Regular and rhythmic compressions also help maintain the effectiveness of blood flow during CPR. This consistency is crucial, as erratic or inconsistent movements can lead to inadequate perfusion and reduced effectiveness of the resuscitation effort. The appropriate pace and force are essential to ensure that compressions are deep enough (about 2 to 2.4 inches for adults) and carried out correctly to achieve the desired physiological effect.
