at heights. the partial pressure of oxygen is less so Hb prefer to bind with carbondoxide.Affinity of Hb towards CO2 is 20-30times more than O2 in normal conditions but partial pressure of oxygen is high on normal altitudes so it bind with O2. but at high altitude partial pressure of O2 is less so it donot bind with O2

increasing breathing rate can ensure enough oxygen supply to our body
binding cApacity of Hb with oxygen is decreased and it cause altitude sickness it is not a mechanism to ensure oxygen supply.
brain needs contant oxygen supply. if not it cause anoxia
constant*
do you understand me???
