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's bodies can respond to high altitude in different ways.
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] HAPE is a severe presentation of altitude sickness. Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who ...
A rapid depressurisation to the low pressures of high altitudes can trigger altitude decompression sickness. The physiological responses to high altitude include hyperventilation , polycythemia , increased capillary density in muscle and hypoxic pulmonary vasoconstriction–increased intracellular oxidative enzymes.
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 . CMS typically develops after extended time living at high altitude (over 2,500 metres (8,200 ft)).
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 86-year-old was in Antarctica to see an environment that is the closest on Earth to what it's like on Mars when he became short of breath.
Mild cases of the "bends" and some skin symptoms may disappear during descent from high altitude; however, it is recommended that these cases still be evaluated. Neurological symptoms, pulmonary symptoms, and mottled or marbled skin lesions should be treated with hyperbaric oxygen therapy if seen within 10 to 14 days of development. [102]
Dust and allergens in the home can trigger sneezing, coughing and other heater sickness symptoms. Lizarzaburu recommends vacuuming and dusting your living environment regularly to help minimize ...
