What indicates effective chest compressions during CPR?

Effective chest compressions during CPR are indicated by the visible rise and fall of the chest. This observable movement is crucial because it demonstrates that there is sufficient force being applied to the chest to generate adequate blood flow and facilitate oxygen delivery to the brain and vital organs. The rise and fall of the chest reflect that there is enough pressure created during compressions to temporarily disrupt the intrathoracic pressure, allowing for proper ventilation.

When the chest visibly rises, it signifies that air is being effectively drawn into the lungs, which is essential for providing oxygen to someone who is unresponsive and not breathing adequately. This sign is a critical measure of effective CPR, as it ensures that the rescuer is providing compressions at the right depth and rate, aligning with current guidelines that emphasize high-quality, effective compressions for improving survival outcomes in cardiac arrest situations.

In contrast, minimal chest movement could suggest inadequate compression depth, while obtaining a pulse and listening for breath sounds are not valid indicators of effective compressions during CPR itself.
