Is high altitude bad for aortic aneurysms?

Depends: This is a difficult one to answer. The changes that may occur at high altitude, such as relatively less oxygen may lead to increased heart rates, especially with exertion, and that is an undesirable effect. However, more details are needed: location of the aneurysm? Size and the etiology of the aneurysm?M how far above sea level is your location? What would be a rate of ascent? ...Read more

High Altitude (Definition)

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

How does the body acclimate itself to high altitude?

How does the body acclimate itself to high altitude?

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 (sodium 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

Not a problem: Assuming your general health is good enough to permit higher altitudes, just use your CPAP machine as usual. It will work as it always does. Of course, you will have less oxygen in the ambient air, but it will continue to do it's job. If you don't have a cpap, get one, or if intolerant of its use, see your dentist about having an oral appliance made as an alternative. ...Read more

Can I have a retinal hemorrhage from high altitude?

Yes, however:: At altitude above 4300 meters, there are certainly reports of retinal hemorrhage but it can be difficult to exclude other causes.High altitude retinopathy (harh) is seen in up to 29% of everest climbers above 5300 meters. There seems to be an association with altitude sickness raising questions whether slow ascent ; other factors may reduce risk for bleeding in the small vessels of the eye. ...Read more
