What is a risk associated with performing chest compressions too quickly?

Performing chest compressions too quickly can lead to reduced blood flow to the brain and vital organs. The primary goal of chest compressions during cardiopulmonary resuscitation (CPR) is to circulate blood effectively to maintain perfusion of vital organs and the brain. When the compressions are too rapid, it can negatively impact the hemodynamics of blood flow. Specifically, a high rate of compressions may not allow sufficient time for the heart to fill with blood between compressions, leading to inadequate stroke volume and ultimately reducing the overall cardiac output. This means that even though compressions are being delivered, they may not be effective in maintaining an adequate supply of oxygenated blood to critical areas, which can compromise survival outcomes.

In contrast, while compressions that are too fast can lead to problems such as rib fractures or fatigue for the rescuer, or may decrease the effectiveness of rescue breaths, it is the compromised blood flow to the brain and organs that poses the most immediate risk in terms of patient outcomes during a cardiac arrest scenario.
