Which factor is essential for effective CPR compressions?

Effective CPR compressions require compressing the chest to a depth of at least 2 inches in adults. This depth is crucial because it allows for adequate circulation of blood, ensuring that oxygen reaches vital organs during cardiac arrest situations. Shallow compressions may not create enough pressure to propel blood through the heart and into the rest of the body, reducing the chances of survival and recovery.

Compressions at this specified depth also help maintain proper blood circulation and assist in the effective function of the heart during CPR. This is based on research and guidelines established by organizations such as the American Heart Association. Therefore, focusing on achieving and maintaining the correct compression depth is a key aspect of effective CPR performance.
