It is the accumulation of liquid inside the lungs that occurs at an altitude of more than 8202 ft / 2500 m, as a result of the difference in pressures generated at an altitude of more than 8202 ft / 2500 m above sea level.
The amount of oxygen in the air decreases and therefore also in the organs and blood, causing high blood pressure in the lungs and water retention.
This situation causes fatigue, slower recovery from exertion, progressive respiratory difficulty (with altitude), cough and frothy expectoration.
It is diagnosed by the described symptoms that appear when ascending at altitude.
Treatment is urgent and involves a rapid descent to altitude and oxygen therapy. Acetazolamide, dexamethasone and beta 2 agonists can be used to accelerate recovery.
If the correct treatment is not applied, up to 40% of those affected die.
