What is a potential risk of excessive compression depth during CPR?

The chosen answer, which highlights the increased risk of organ damage, is foundational to understanding the mechanics of CPR and the physiological effects exerted on the body during resuscitation efforts.

During cardiopulmonary resuscitation (CPR), compressing the chest too deeply or with excessive force can lead to significant internal trauma. Organs such as the lungs, liver, and spleen are particularly susceptible to injury from high-pressure compressions. For instance, deep compressions might cause rib fractures, which can puncture the lungs or lead to internal bleeding, especially in patients who might already have weakened bone structures or pre-existing health issues.

This understanding emphasizes the importance of maintaining the recommended compression depth during CPR, which is 5 to 6 centimeters in adults, rather than exceeding it in an attempt to enhance circulation. While effective compressions are critical for maintaining blood flow to vital organs, it is essential to balance the force applied to prevent additional harm.
