Altitude sickness

Altitude sickness (synonym mountain sickness) is a syndrome caused by lack of oxygen partial pressure in the air we breathe at rises to higher altitudes. The result is oxygen starvation breaks the function of nervous, respiratory and cardiovascular systems. Observed changes in the organs of digestion, endocrine glands, muscles. Develop symptoms of hypoxia.
Altitude sickness share in the high-rise (the disease aviators) and mountain sickness, in development of which play a role, and such additional factors as physical fatigue, cooling, ionized air and ultraviolet radiation. Up to a height of about 2000-2500 m the oxygen saturation of arterial blood almost not changed as a result of compensatory mechanisms.
In the elderly signs of altitude sickness can occur at an altitude of 1000 m, trained young people is at the height of 4,000 meters Altitude of 3000 - 4000 meters is considered to be the boundary of the anoxic flight (and recovery). Especially sharply the symptoms of altitude sickness are expressed at altitudes over 5000 m altitude 6000 m and more quickly arises the danger of death acute oxygen deficiency.
The main features of the actual altitude or mountain sickness is the same: shortness of breath, palpitations, dizziness, headache, noise in the ears, increased heart rate, muscle weakness, nasal bleeding, nausea, vomiting, drowsiness. At the further development of altitude sickness are observed cardiac decompensation, loss of consciousness, cessation of breathing and cardiac arrest. The speed of development of individual signs of altitude sickness depends on the conditions of its occurrence, as well as from the initial state of the organism. The diagnosis is straightforward. The forecast is favorable at the giving of oxygen or fast decrease to a safe height or land.
Treatment is fast descending, provision of complete rest, periodic breathing oxygen and Carbogen, warm body heaters; symptomatic funds - liquid ammonia (sniff), caffeine-benzoate sodium 1 ml of 10% solution under the skin, acetylsalicylic acid 0.5 g 3 times a day, cardio-vascular equipment - kordiamin 1 ml under the skin.
Prevention is the gradual adaptation (adaptation) to the height (through training) and acclimatization to the high altitude climate, eating acidic foods (for example, a mixture of lemon acid with sugar), ascorbic acid, climbing to higher altitudes only with oxygen devices.
