Physicians at mountain resorts commonly provide this treatment.Ī Gamow bag: This portable, plastic hyperbaric chamber can be inflated with a foot pump and is used when a rapid descent is not possible. Pure oxygen: Giving pure oxygen can help a person with severe breathing problems caused by altitude sickness. Once acclimatized they may be able to ascend once more. These include:ĭescending: Moving to a lower altitude is usually the best action to take if a person develops symptoms of altitude sickness. There are a number of potential treatments that may remedy altitude sickness. Those with more severe symptoms should rest, consume plenty of fluids, and avoid anything that may affect blood oxygen levels, such as smoking.
However, if a person experiences even slight symptoms, they should alert others. People with very mild symptoms may continue ascending but should go at a much slower pace. Rising to higher altitudes can also cause fluid to leak from tiny blood vessels, resulting in a potentially dangerous fluid buildup in the lungs and the brain. The body may also respond to a change in altitude by altering blood acidity level, lung pressure, electrolyte levels, and fluid and salt balance. People who do not spend enough time acclimatizing to a new altitude before progressing further have the highest risk of developing altitude sickness. The average human body needs from 1 to 3 days to become acclimatized to a change in altitude. However, even though breathing faster increases blood oxygen levels, they do not reach sea level concentrations. In response, the body creates more red blood cells to carry more oxygen. This raises their pulse and their breathing rate. If a person has less oxygen in their blood, their heart and lungs have to work harder. Lower pressure means that the air is less dense, and therefore the number of oxygen molecules per breath is reduced.Īt around 18,000 ft, each breath contains approximately half of the oxygen found at sea level. For example, at the peak of Mount Everest, air pressure is around 228 mm Hg. Staying at high altitudes for extended periods may also cause forms of altitude sickness.Īt sea level, the oxygen concentration in the air is approximately 21%, and air pressure averages 760 millimeters of mercury (mm Hg).Īt higher altitudes, the oxygen concentration remains the same, but air pressure is much lower. The leading cause of altitude sickness is ascending to a great height too rapidly.
