What is the recommended compression depth for CPR in adults?

The recommended compression depth for CPR in adults is 2 inches. This depth is essential to ensure that adequate blood flow is generated to the brain and vital organs during cardiac arrest. Achieving a compression depth of 2 inches helps to effectively compress the chest cavity and creates enough pressure to circulate blood.

Depth of compressions is critical because too shallow compressions may not be effective in perfusing vital organs, while overly deep compressions could potentially cause injury to the chest wall or internal structures. Thus, adhering to the guideline of compressing at least 2 inches strikes a balance between efficacy and safety, maximizing the chances of survival until professional medical help can arrive.
