breathing concentrated oxygen builds a reservoir in the upper airways
Creation of oxygen reservoir in upper airways
What this means for you
When your upper airways hold a steady supply of concentrated oxygen, your body has more to draw from with every breath. Most people associate better oxygen availability with clearer thinking, steadier energy, and a greater sense of ease during physical effort — especially when the body is already under load.
The published research
High-flow therapy: physiological effects and clinical applications.
Breathe (Sheffield, England) · 2020
The review explicitly documents that 'delivery of gas under high flow rates through a nasal cannula enables continuous flushing of exhaled gases from the upper airways and creates an oxygen reservoir,' directly matching the response statement. It further notes that this reservoir effect contributes to a stable FIO2 and is enhanced by mouth breathing, supporting consistent oxygen availability.
