What is a key sign of effective chest compressions during CPR?

Visible rise and fall of the chest is a key sign of effective chest compressions during CPR because it indicates that sufficient volume is being delivered into the lungs, promoting oxygenation and circulation. When compressions are done correctly, the chest will compress and then return to its normal position, allowing air to enter the lungs. This visual cue serves as an immediate feedback mechanism for healthcare providers, ensuring that their technique is effective and that they are generating sufficient tidal volume to support the patient’s needs.

In contrast, decreased heart rate, while it may occur in certain scenarios of resuscitation, does not directly reflect the effectiveness of the compressions. Similarly, patient regaining consciousness is more of a long-term outcome rather than an immediate sign of effective CPR. Increased respiratory rate can be a result of many factors and does not specifically indicate that chest compressions are being performed effectively. Thus, the visible rise and fall of the chest during compressions is the most reliable indicator of effective technique.
