title: Southwestern Internal Medicine Conference: pulmonary complications of high-altitude exposure.
abstract: The primary physiologic disturbance at high altitude is hypoxemia, which leads to a cascade of secondary changes in each step of the oxygen-transport chain. The author, in this review, focuses on the alterations in ventilatory control and alveolar-capillary gas exchange at high altitude and discusses the clinical pulmonary complications associated with these alterations, as well as their prevention and management.
