How deep should chest compressions be for adults?

Chest compressions for adults should be at least 2 inches deep to be effective in providing adequate circulation during cardiopulmonary resuscitation (CPR). This depth is crucial as it allows for sufficient compression of the heart, facilitating the necessary blood flow to vital organs, particularly the brain, during cardiac arrest.

Compressions that meet or exceed this depth also ensure that pressure is applied effectively to create the necessary blood flow while minimizing the risk of injuries caused by either insufficient or overly forceful compressions. The recommendation for a depth of at least 2 inches aligns with guidelines established by leading resuscitation organizations, which emphasize the importance of achieving this depth to maximize the chances of survival and recovery. Therefore, understanding that chest compressions must be of adequate depth is essential for effective CPR delivery.
