DHO First Aid Practice Test

Laying a victim who has difficulty breathing on their back with the head slightly raised is the correct approach because this position can facilitate easier airflow into the lungs. Elevating the head helps to open up the airways, reducing any potential obstruction caused by the tongue or pharyngeal tissues. This position can also alleviate pressure on the diaphragm, making it easier for the victim to take deeper breaths.

The elevation allows gravity to assist with lung expansion and can be especially beneficial for individuals experiencing respiratory distress or conditions like asthma. It also aids in comfort and can help to relieve anxiety, which frequently accompanies breathing difficulties.

In contrast, laying flat on their back without elevation may hinder breathing efforts, particularly in cases where the victim might be experiencing fluid buildup or swelling in the airways. Being on their side might be beneficial in certain situations, but it is usually not the most effective for maximizing airflow as the semi-upright position does. Laying flat on their stomach is typically not advisable for anyone struggling to breathe, as it can further compress the chest and restrict lung expansion.
