Which of the following is NOT a sign of effective CPR?

An effective CPR process is characterized by several key indicators that demonstrate the proper delivery of chest compressions and ventilations. The correct answer indicates a condition that should not be present during effective CPR.

When performing CPR correctly, the goal is to maintain blood flow to vital organs, which is reflected in several observable signs. Minimal pauses in compressions ensure that the heart is being continuously pumped, thereby maximizing the perfusion of blood to critical organs. Visible chest rise with breaths confirms that the air is being adequately delivered to the lungs, ensuring that oxygen is reaching the bloodstream.

In a scenario where CPR is being effectively administered, a decreased heart rate is not typically expected. Instead, chest compressions should lead to an increased heart rate and improved hemodynamics following resuscitation efforts. A color change in the patient’s skin may indicate poor perfusion or hypoxia, which should improve with effective CPR, rather than serving as a sign of its effectiveness.

Thus, a decrease in heart rate during compressions does not align with the expectations of effective CPR, making this condition an indicator of ineffective CPR rather than a sign of success in resuscitation efforts.
