During CPR for adults, what is the depth of chest compressions recommended?

The recommended depth of chest compressions during CPR for adults is about 2 inches. This depth ensures that sufficient force is applied to create blood flow and maintain circulation during cardiac arrest. Compressions that are too shallow may not effectively circulate blood, which is critical for the brain and vital organs to receive oxygen during this life-threatening situation. The 2-inch depth guideline is supported by the American Heart Association and is set to achieve optimal results in resuscitation efforts. This measure reflects a balance between delivering strong enough compressions to sustain blood flow while also minimizing the risk of injury from excessively deep compressions.
