The concentration of oxygen (O2) in sea-level air is 20.9%, so the partial pressure of O2 (pO2) is 21.136 kilopascals (158.53mmHg). The increased levels of erythrocytes causes increased blood viscosity and uneven blood flow through the lungs (V/Q mismatch). You need medical treatment for HACE. [7], Atmospheric pressure decreases exponentially with altitude while the O2 fraction remains constant to about 100km (62mi), so pO2 decreases exponentially with altitude as well. Though symptoms and their progression vary, a single responsetaking the person to a lower altitudeis the most effective treatment for all of these conditions.

Patients with HAPE who have access to oxygen (at a hospital or high-altitude medical clinic, for example) may not need to descend to lower elevation and can be treated with oxygen at the current elevation. Altitude For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP. Conclusions: Acetazolamide, the first efficient pharmacologic treatment of chronic mountain sickness without adverse effects, reduces hypoventilation, which may be accentuated during sleep, and blunts erythropoiesis.
