As one ascends through the atmosphere, every breath contains fewer molecules of oxygen. One must work harder to obtain oxygen, by breathing faster and deeper. The % of oxygen in the atmosphere at sea level is 21%. As altitude increases, the % remains the same but the number of oxygen molecules per breath is reduced. At 12, 000 feet 40% fewer oxygen molecules per breath. Your ...Read more
Can high altitude cause hypertension or aggravate it if it already exists? If so what causes this?
No, Internal Control: Bp: a result of cardiac output vs. Average resistance of the 20, 000 to 30, 000 end arteries (arterioles) which determine blood flow to each capillary bed, both co ; size of all arterioles (degree of constriction) are under split-second control from brain ; constantly being adjusted. BP is just a momentary result. Brain integrates many variables, including perceptions/feelings ; adjusts accordingly. ...Read more

However, in certain people they are not able to compensate. The proton pumps that maintain the blood brain barrier cease to function and there is extra fluid (edema) in the brain that leads to brain swelling. This can lead to death. ...Read more

Many changes: 1. You breath faster to compensate for the thinned density of oxygen. 2 body makes more oxygen carrying red cells at altitude 3. Kidneys put out more bicarbonate to keep your acid base state adjusted. Your rapid breathing blows off carbon dioxide and your kidneys adjust for this change but it takes a few days to body to alter. There are medicines to speed this acclimatization. ...Read more
