Millions of people visit high-altitude regions annually and more than 80 million live permanently above 2,500 m. Acute high-altitude exposure can trigger high-altitude illnesses (HAIs), including acute mountain sickness (AMS), high-altitude cerebral oedema (HACE) and high-altitude pulmonary oedema (HAPE). Chronic mountain sickness (CMS) can affect high-

American Industrial Hygiene Association Journal, 1966
Abstract The William P. Yant Memorial Award was established shortly after the death of Dr. Yant and was presented for the first time in 1965. The 1966 Yant Award, the second such presentation, was given to Dr. Alberto Hurtado, Research Director of the High Altitudes Research Institute, Peruvian University of Medical and Biological Sciences.

High altitude retinopathy (HAR) was first described in 1969 as engorgement of retinal veins with occasional papilloedema and vitreous hemorrhage. Since then various studies have attempted to define the incidence, etiology and significance of this phenomenon, usually with small numbers of subjects. Recently studies on relatively large groups of subjects

On the altitudes of quadrilaterals
International Journal of Mathematical Education in Science and Technology, 2005In this article quadrilaterals with concurrent maltitudes are characterized. A generalization of the maltitudes is given, and a larger family of quadrilaterals for which an analogous property of concurrency holds is determined and studied.

Emergency Medicine Clinics of North America, 1984
Altitude illness is a group of synergistic physiologic disturbances, each of which may occur alone but which more commonly occur together, with one dominating the clinical picture. Treated promptly, altitude illness is readily reversible with full recovery; procrastination may lead to death or disability.

The Journal of the Royal Aeronautical Society, 1937
In the present paper (Part II) the engine, and more broadly the power plant, is considered in its relation to altitude. The discussion hinges mainly on the question of supercharge. After a brief reference to the various types of supercharger the author opens the discussion on an ideal basis, in which the supercharger is supposed to be 100 per cent ...

Ebert-Santos, Christine, and Ana Campos. Ileus at altitude. High Alt Med Biol. 25:342-344, 2024.-Autoimmune myasthenia gravis (MG) is a condition commonly caused by the production of antibodies that block acetylcholine receptors. Until recently, gastrointestinal (GI) symptoms were considered rare in myasthenia gravis, but are now being proposed as an ...

Altitude Sensing for Automatic Altitude Reporting
IRE Transactions on Aeronautical and Navigational Electronics, 1961A short resume is given of the means used to measure altitude for reporting purposes, possible sources of error, followed by a description of three of the most commonly used analog-digital converters.

The relationship between altitude and the development of paragangliomas (PGLs), rare tumors within the sympathetic nervous system has been suggested since the early 1970's. Here, we discuss how altitude, marked by lower barometric pressure and hypoxia (reduced oxygen partial pressure), may influence cancer rates.

The Lancet Respiratory Medicine, 2012
Medical problems occur at high altitude because of the low inspired Po(2), which is caused by the reduced barometric pressure. The classical physiological responses to high altitude include hyperventilation, polycythemia, hypoxic pulmonary vasoconstriction-increased intracellular oxidative enzymes, and increased capillary density in muscle.
