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 ...
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 ...
Ecuador is divided into four geographic regions; the Andes, the Amazon Basin, the Coast, and the Galapagos Islands. Harsh climates in each region pose several threats to human health. [19] Due to the lack of oxygen in the Andes because of high altitude, altitude sickness may arise, primarily in tourists coming from low-altitude regions. [20]
Methods of mitigating the effects of the high altitude environment include oxygen enrichment of breathing air and/or an increase of pressure in an enclosed environment. [1] Other effects of high altitude include frostbite, hypothermia, sunburn, and dehydration. Tibetans and Andeans are two groups which are relatively well adapted to high ...
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)).
High-altitude cerebral oedema [1] (HACO) 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.
The most obvious and direct application of high-altitude research is to understand altitude illnesses such as acute mountain sickness, and the rare but rapidly fatal conditions, high-altitude pulmonary edema ( HAPE) and high-altitude cerebral edema ( HACE ). [1] [2] Research at high altitude is also an important way to learn about sea level ...
Edward Whymper FRSE (27 April 1840 – 16 September 1911) was an English mountaineer, explorer, illustrator, and author best known for the first ascent of the Matterhorn in 1865. Four members of his climbing party were killed during the descent. [ 1 ][ 2 ] Whymper also made important first ascents on the Mont Blanc massif and in the Pennine ...
