This review provides detailed information about each of these important clinical entities. After reviewing the clinical features, epidemiology and current understanding of the pathophysiology of each disorder, we describe the current pharmacological and nonpharmacological approaches to the prevention and treatment of these diseases.Lack of acclimatisation is the main risk factor for acute altitude illness; descent is the optimal treatment http://ow.ly/45d2305JyZ0
