What is the minimum depth for compressions during adult CPR?

The minimum depth for compressions during adult CPR is 2 inches. This depth is critical because it helps ensure that the compressions effectively circulate blood and maintain perfusion to vital organs, especially the heart and brain.

Compressing the chest to this depth provides sufficient pressure to overcome the resistance of the chest wall, allowing for adequate blood flow during each compression. Studies and guidelines from organizations like the American Heart Association emphasize the importance of this depth to optimize outcomes in cardiac arrest situations.

Compressions that are shallower than 2 inches may not generate enough pressure to be effective in restoring blood flow, which is why guidelines specify this minimum depth. At the same time, excessive compression depth can lead to injuries or complications, highlighting the importance of adhering to this guideline for effective CPR.
