The effectiveness of CPR is primarily evaluated by observing the return of spontaneous circulation (ROSC) and improvement in vital signs. ROSC indicates that the heart has begun to beat again effectively after cardiac arrest, which is a critical hallmark of successful resuscitation efforts. Additionally, monitoring vital signs such as blood pressure, heart rate, and oxygen saturation provides further confirmation that perfusion to vital organs is being restored and that the patient is stabilizing.

Assessing the patient's responsiveness can provide some information about neurological function, but it does not offer direct insight into the effectiveness of the CPR being performed. Similarly, while blood pressure monitoring is essential in overall patient evaluation, it may not accurately reflect the immediate effectiveness of CPR until ROSC is achieved. The presence of spontaneous breathing signals improvement but is not as definitive as ROSC in assessing the success of CPR. In summary, monitoring for ROSC and vital signs is the most reliable method to evaluate the effectiveness of CPR.
