Effect of simulated altitude on blood gas transport in the pigeon.
Unacclimated pigeons were exposed to various simulated altitudes. Arterial and mixed venous blood gas levels were measured. At the highest altitude 9150m (Pb = 235 mm Hg) a remarkable degree of alkalosis was tolerated for several hours without ill effecrtant factor in the bird's ability to survive such altitudes.
