How is the effectiveness of CPR typically measured?

The effectiveness of CPR is typically measured by evaluating the quality of chest compressions and the presence of Return of Spontaneous Circulation (ROSC). High-quality compressions, characterized by adequate depth, rate, and minimal interruptions, are essential for successful resuscitation efforts. Additionally, the detection of ROSC is a critical indicator that circulation has resumed and the patient may have a chance for recovery. Monitoring these parameters helps assess whether the CPR being administered is effective and achieving the desired physiological responses.

While other methods, such as checking blood pressure or assessing consciousness, can provide information about a patient's overall status, they are not reliable indicators of the immediate effectiveness of CPR. Instead, the primary focus during CPR is ensuring that the compressions are being delivered effectively and monitoring for signs that the heart has resumed normal function.
