What is the recommended depth of chest compressions for adult CPR?

The recommended depth of chest compressions for adult CPR is between 2 to 2.4 inches. This depth is crucial as it ensures that enough force is applied to generate adequate blood flow during cardiac arrest. Adequate compressions not only help to maintain circulation but also improve the chances of restoring a normal heart rhythm when combined with other resuscitation techniques. Compressions that are too shallow may not be effective in delivering blood to vital organs, whereas excessively deep compressions can lead to injuries to the chest and ribs. Therefore, following the current guidelines that specify a depth of 2 to 2.4 inches is essential for effective CPR.
