which of the following will likely occur in an individual who has just reached the peak of mount mc kinley
1.O2-Hb curve shift to right
2.respiratory alkalosis.
3.increased erythropoietin release
4pulmonary vasoconstriction
5.all of the above


ans is 5.all
I can understand all the points except 2 according to me it should b respiratory acidosis why respiratory alkalosis.
plz can any body explain this

high on mountain -indicates hypoxia..........
hypoxia induces hyperventilation,means increased breathing..
hyperventilation leads to hypocapnia(increased blowing off of co2),means respiratory alkalosis..
