breathing high-flow oxygen flushes out stale air in upper airways, improving CO2 clearance
High-flow nasal cannula washes out anatomic dead space and improves gas mixing in large airways, contributing to more efficient CO2 clearance.
What this means for you
When stale, CO2-rich air is cleared from your upper airways between breaths, your lungs work more efficiently with every inhale. This means fresher oxygen reaches deeper into your respiratory system — something many people notice as a clearer head, easier breathing, and a greater sense of calm and energy.
