When hiking in the mountains at 12,000 ft of elevation, the atmospheric pressure is about 483mmHg. Oxygen makes up ~14% of alveolar air. The alveolar (lung) PO2 (partial pressure of oxygen) would be 66mmHg 760mmHg( 66mmHg, 760mmHg ), which will result in less more( less, more ) oxygen moving into the blood compared to what you would experience at sea level, where the atmospheric pressure is higher lower( higher, lower ).
