Descent is mainstay of altitude illness treatment

Altitude illness is best handled by stopping further ascent, but severe or persistent symptoms require descending, aided by oxygen and drug treatment. In a clinical review, Barry and Pollard (p 915) explain the symptoms and forms of the illness and the available treatments. In most cases, altitude illness is a self limiting and benign syndrome, but it can progress to life threatening forms, such as pulmonary or cerebral oedema. It is common in travellers to altitudes over 2500 m, and the mainstay of treatment is descending. The authors say that doctors should view oxygen and drug treatment as adjuncts to aid descent.
