How deep should compressions be for adults during CPR?

During CPR for adults, the recommended depth for chest compressions is at least 2 inches. This guideline is based on research indicating that compressions within this range are more effective in generating blood flow to vital organs, particularly the heart and brain. Compressions that are too shallow may not create sufficient pressure to circulate blood, which could significantly diminish the chances of survival in a cardiac arrest situation.

The emphasis on this depth ensures that the compressions are not only effective but also within a range that can be safely administered without causing injury. The goal during CPR is to provide strong, effective compressions at a rate of 100 to 120 per minute, which paired with the correct depth maximizes the chances of a successful outcome.
