What is the importance of watching for chest rise when delivering rescue breaths?

Watching for chest rise when delivering rescue breaths is crucial because it serves as an indicator of effective ventilation. When rescue breaths are administered, the goal is to deliver enough air to inflate the lungs, which leads to visible movement of the chest. This chest rise confirms that air is entering the lungs properly. If there is no chest rise, it may indicate that the airway is obstructed or that the technique being used for delivering breaths is not effective.

This feedback helps rescuers understand whether they need to adjust their approach, such as repositioning the airway, ensuring a proper seal around the victim's mouth, or identifying other potential issues. Effective ventilation is paramount in a cardiac arrest situation as it helps to oxygenate the blood, supporting the patient's chances of recovery. Therefore, confirming chest rise during rescue breaths directly correlates with the efficacy of the lifesaving measures being performed.
