We discuss the use of hypoxic generators to pre-acclimatize for 8000 meter mountains by Everest Climbers (without supplemental Oxygen) Killian Jornet, Adrian Ballinger, and Emily Harrington. We discuss the academic evidence for pre-acclimatization and why the published studies are lagging industry practice.

We talk about why pre-acclimatization with normabaric hypoxic generators makes sense for high-altitude mountaineering above 5,000 meters or 16,000 fee for people who have jobs. Most of the folks that can attempt high-altitude summits live far below 8,000 feet or 2,500 meters and have to acclimatize for weeks to attempt Aconcagua 6961 meters or 22,837 feet or months to attempt Mount Everest.

Your blood ox % should fall while in the tent or on the mask and your pulse rate should rise. Pulse ox meters are key to measuring the effectiveness of simulated altitude training.

Acclimatization stimulates the production of red blood cells and reduces the risks of developing symptoms of acute mountain sickness (AMS) on your ascent of a high to extreme altitude peak. AMS symptoms are headache, nausea, shortness of breath, difficulty breathing, and dizziness. More sever AMS are high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE) which can be life threatening if the climber cannot descend quickly.

We translate the settings into simulated altitude and suggest an acclimatization plan. This IS NOT medical or exercise advice. These are just the opinions of someone who has NO medical or exercise training. You should consult a physician and do your own readings of the academic research. Two studies we liked were
