Partial pressure of oxygen in ambient air through to mixed venous blood varies with altitude. Diagram shows representative resting levels at sea level and 5800 m

Calculated time course for change in partial pressure of oxygen in pulmonary capillary. At sea level oxygen pressure reaches almost alveolar levels in a third of available time. At the summit of Mount Everest the mixed venous oxygen pressure is lower and never reaches alveolar levels
