Cardiopulmonary Resuscitation (CPR) Practice

Effective chest compressions during CPR can be assessed by observing the rise and fall of the chest with each compression, indicating that air is moving in and out of the lungs, which shows that ventilation is being supported. Additionally, if the victim's heart begins to regain activity, a pulse may be felt, further confirming that blood circulation is being restored.

This option reflects the essential goal of CPR, which is to maintain blood flow and provide oxygen to vital organs until definitive medical help arrives. The visible rise and fall of the chest is a clear indicator that air is being pushed into the lungs, facilitating gas exchange essential for survival.

The other options do not effectively gauge the quality of chest compressions or the outcomes we aim for in a resuscitation effort. For example, the notion that the chest should turn red is not a reliable measure of effective compressions and could be misleading. An absence of audible sounds does not necessarily imply effective compressions, as sounds may be dependent on various other factors. Lastly, compressions should be deep and at an appropriate rate to maximize blood flow, making the idea of fast and shallow compressions inappropriate for effective CPR.
