What indicates that CPR is being performed effectively?

Performing CPR effectively is demonstrated by the victim showing signs of life. This includes any indication that the person is regaining consciousness, such as responsiveness, movement, or the ability to breathe on their own. These signs indicate that the brain and vital organs are receiving adequate blood flow and oxygen, which is the primary goal of CPR until further medical help arrives.

The other indicators would not be signs of effective CPR. For instance, a victim remaining unresponsive suggests that circulation is likely not being restored, indicating that CPR may not be effective. Pale skin color is a sign of poor blood flow and is counterproductive to the goal of CPR, which aims to improve oxygenation and perfusion. A decreasing heart rate is also concerning, as it may signify further deterioration of the victim's condition rather than improvement. Hence, the presence of any signs of life is the strongest indicator that CPR is being performed effectively.
