The proportion of oxygen in the air 21% is constant whether at sea level or on the highest peak, but at lower altitudes there is more air pressure to force oxygen into tissue.

As sea level rises, the weight on one end increases, causing the plank to bend so pressure goes up at the end but down in the middle where the plank bends upward (see sketch above).
