Altitude sickness, the mildest form being acute mountain sickness (AMS), is a harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. [1][2][3] People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. [1]
Acetazolamide. Acetazolamide, sold under the trade name Diamox among others, is a medication used to treat glaucoma, epilepsy, acute mountain sickness, periodic paralysis, idiopathic intracranial hypertension (raised brain pressure of unclear cause), heart failure and to alkalinize urine. [2][3] It may be used long term for the treatment of ...
Emergency medicine, wilderness medicine. High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft). [2] However, cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in more vulnerable ...
Acetazolamide is an inhibitor of carbonic anhydrase.It is used for glaucoma, epilepsy (rarely), idiopathic intracranial hypertension, and altitude sickness. For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP.
High-altitude cerebral edema. High-altitude cerebral edema (HACE) is a medical condition in which the brain swells with fluid because of the physiological effects of traveling to a high altitude. It generally appears in patients who have acute mountain sickness and involves disorientation, lethargy, and nausea among other symptoms.
Climbing Mount Rainier.. The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The medical problems that are direct consequence of high altitude are caused by the low inspired partial pressure of oxygen, which is caused by the reduced atmospheric pressure, and the constant gas fraction of oxygen in atmospheric air over the ...
Moderate dose: headache, nausea, weakness, or anxiety Large dose: loss of consciousness Perfluoroisobutene Gas: colorless Odor: none 1-4 hours Flu-like, also eye, nose, and throat irritation, and chest discomfort, or no symptoms Phosgene Gas: colorless Odor: decaying fruit, fresh-cut grass, 1-4 hours; small doses, 24-48 hours
Specialty. Emergency medicine. Chronic mountain sickness (CMS) is a disease in which the proportion of blood volume that is occupied by red blood cells increases (polycythaemia) and there is an abnormally low level of oxygen in the blood (hypoxemia). CMS typically develops after extended time living at high altitude (over 2,500 metres (8,200 ft)).
