How should effectiveness of resuscitation be evaluated during CPR?

Evaluating the effectiveness of resuscitation during CPR is crucial for determining whether the interventions are producing the desired outcomes. Monitoring the responsiveness of the patient is a key indicator of effectiveness because it helps ascertain whether the brain and central nervous system are receiving an adequate supply of oxygen. If the patient begins to show signs of responsiveness, it suggests that circulation has improved, which is a positive sign of resuscitation efforts.

While observing the patient's eyes can offer some information about neurological function, it is not a comprehensive method for assessing the effectiveness of CPR. Checking for pulses intermittently may indicate the presence of circulation; however, it is often not practical during continuous CPR since pulse checks can be time-consuming and may interrupt the flow of chest compressions, which are critical for maintaining blood flow. A combination of pulse checks and ventilations could provide some insights into resuscitation efforts, but again, the priority during CPR should be maintaining good compressions and ensuring adequate ventilation rather than taking pause for multiple checks.

Overall, focusing on the patient's responsiveness directly addresses the goal of resuscitation: restoring adequate oxygenation and circulation, making responsiveness the most informative and direct assessment of CPR effectiveness.
