The influence of oxygen pressure on placental and villous vascular development is reviewed and considered relative to the natural experiment afforded by residence at high altitude. Data obtained from normal high altitude pregnancies are compared with those from IUGR and preeclampsia, conditions believed to be caused by placental hypoxia.

Science and mountain exploration are closely linked throughout history. A large array of studies of varying complexity have been performed in conditions of hypobaric hypoxia, some on field studies, some in hypobaric chambers. The military has contributed greatly to this body of evidence both through operations in high altitude regions of the world ...

High-altitude illnesses have profound consequences on the health of many unsuspecting and otherwise healthy individuals who sojourn to high altitude for recreation and work. The clinical manifestations of high-altitude illnesses are secondary to the extravasation of fluid from the intravascular to extravascular space, especially in the brain and lungs.

Abstract High altitude deterioration means a gradual diminution in man’s capacity to do work at great heights. This is associated with insomnia, lack of appetite, loss of weight and increasing lethargy. These symptoms appear after a prolonged stay above 18000 ft. and there is great individual variation.

To the Editor.— In regard to the question on pitting leg edema after a backpacking trip (238:1957, 1977), it would be important to know if the physician experienced edema during or after a backpacking trip to an altitude exceeding 2,400 m. Many hikers experience moderate facial and lower extremity edema during exposure to high altitude with a diuresis

New arrivals to altitude commonly experience poor-quality sleep. These complaints are associated with increased fragmentation of sleep by frequent brief arousals, which are in turn linked to periodic breathing. Changes in sleep architecture include a shift toward lighter sleep stages, with marked decrements in slow-wave sleep and with variable ...
