Oxygen vs. No Oxygen: The Summit Statistics

The Reality of Breathing at the Mount Everest Summit

A Breath of Life

97% of successful Mount Everest summit attempts use supplemental oxygen. The remaining 3% are elite athletes who redefine human limits on a Mount Everest expedition.

The Success Gap

Climbers using 'Os' have a significantly higher success rate. Oxygen keeps the body warm and the mind clear, which is vital for navigating the technical sections of the Mount Everest summit ridge.

The Health Toll

Climbing without oxygen causes permanent brain cell loss and severe frostbite risk. It is a level of Mount Everest expedition intensity that very few humans can safely endure.

Modern Flow Rates

Modern regulators allow for higher flow rates, making the Mount Everest summit feel like 6,000m instead of 8,848m. This technology has opened Everest trekking peaks to a wider range of climbers.

No Shame in Support

Supplemental oxygen is the safety net of the Mount Everest expedition. Use it to ensure you return home to share your summit story.
