What is the most effective method to monitor the success of resuscitation during CPR?

The most effective method to monitor the success of resuscitation during CPR is based on changes in heart rate. As the heart begins to respond to resuscitative efforts, a return of the pulse or heart rate can indicate that circulation is being restored. During effective CPR, the focus is on ensuring that the heart is pumping adequately again; therefore, observing the heart rate offers the best immediate feedback regarding the effectiveness of the resuscitation efforts.

While respiratory rate is important in assessing breathing and can indicate improvements in the patient’s condition, it does not provide direct information about cardiac function or circulation during CPR. The reactivity of pupils to light is more of a neurological indicator and can take time to show changes post-resuscitation, making it less reliable for immediate monitoring. Blood pressure is also critical; however, it can be challenging to measure accurately during CPR, especially in pediatric patients, thus limiting its effectiveness as a direct measure during the resuscitation process.
