Which method is primarily employed to check breathing in a casualty?

The look-listen-feel technique is the primary method employed to check breathing in a casualty because it provides a systematic approach to assessing respiratory function.

This technique involves several steps. First, the caregiver should look for chest movement to identify visible signs of breathing. Next, they listen for breath sounds at the casualty's mouth or nose, which can indicate airflow. Finally, the feel component involves checking for airflow against the caregiver's cheek or feeling for chest rise and fall. This comprehensive approach allows the caregiver to effectively determine if the casualty is breathing normally, abnormally, or not at all.

Employing this technique helps ensure that all aspects of breathing are considered, leading to a more accurate assessment of the casualty's respiratory status.
