What is a consequence of an excessively high compression rate during CPR?

The consequence of an excessively high compression rate during CPR is that it can hinder the passive filling of the ventricles. During cardiopulmonary resuscitation, compressions need to be performed at an optimal rate, typically between 100 to 120 compressions per minute. If compressions are delivered too rapidly, there is insufficient time for the heart to refill with blood in between compressions. This impairs the ability of the heart to generate adequate stroke volume and consequently affects overall cardiac output.

Inadequate passive filling can lead to decreased coronary perfusion pressure, which is essential for resuscitation efforts, as it can reduce the likelihood of achieving a successful return of spontaneous circulation (ROSC). Maintaining a proper compression rate is vital for maximizing the effectiveness of CPR and enhancing the chance of recovery.

The other options relate to significant issues that can arise during improper CPR but do not specifically address the primary impact of a high compression rate on cardiac physiology as it pertains to filling dynamics.
