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

The Reilly method of air conservation emphasizes techniques that can help firefighters manage their air supply more effectively during operations. Humming is a key component of this method. When a firefighter hums, the activity tends to slow down the breathing rate, create a slight vibration in the throat that can help maintain an open airway, and can reduce the overall oxygen consumption. This practice encourages a calm and controlled breathing rhythm, allowing for better air management during critical situations.

While other strategies such as visualization, stepped breathing, and counting may be helpful in various contexts for stress management or breathing control, they are not specifically highlighted as components of the Reilly method in the same way that humming is recognized. Humming serves a unique purpose in optimizing air efficiency by promoting an awareness of breathing patterns and helping to conserve air supply, which is essential for firefighters relying on limited air supplies during emergency response.
