During CPR, what should be monitored for signs of effective compressions?

Monitoring for visible chest rise during cardiac arrest and CPR is crucial because it is a clear indicator that effective compressions are being delivered to the patient. When performed correctly, chest compressions create enough pressure to allow the heart to circulate blood, which in turn facilitates oxygen delivery to vital organs. Visible chest rise demonstrates that air is being pushed out of the lungs, indicating that there is adequate depth and force behind the compressions.

While patient responsiveness may be measured after CPR efforts, it is not an immediate sign of the effectiveness of the compressions themselves. Similarly, heart rate increase can take time to manifest after effective compressions and may not provide instant feedback during the procedure. Changes in a patient's facial color can occur due to a variety of factors during a medical emergency, and are not solely indicative of compression effectiveness. Therefore, visible chest rise is the most direct and observable measure to ensure that compressions are effectively enhancing circulation during CPR.
