Which is a component of the Reilly method of air conservation?

The Reilly method of air conservation is a technique developed to help firefighters manage their air supply during operations, particularly in high-stress situations such as firefighting. Humming is considered a component of this method because it serves multiple purposes.

When a firefighter hums, it creates resistance to airflow, which can slow down the breathing rate and prolong the duration of air supply in the tank. This practice also encourages a more controlled and rhythmic breathing pattern, which is essential in maintaining composure during challenging scenarios. Additionally, humming can help to reduce anxiety and improve focus, which are crucial when operating in environments filled with smoke or other stressors.

Understanding the role of humming within the Reilly method emphasizes the importance of conscious breathing techniques in maximizing the efficiency of air use, supporting the overall objective of air conservation during firefighting operations.
