when you reach the 20,000 ft mark.
respiratory system
That's called - Oxygen.
Yes, the brain is supplied with blood that carries oxygen.
By combining both electrons and protons, oxygen forms into water. O2 + 4e- + 4H+ > 2H2O
At high altitudes the blood has an increased amount of haemoglobin allowing it to carry the same amount of oxygen over all. In the external links view the page and scroll to the bottom.
The overwhelming majority of climbers that summit mount Everest use supplemental oxygen. A handful of climbers are able to do it without the use of supplemental oxygen. Reinhold Messner was the first person to summit mount Everest without supplemental oxygen in 1978. Ones ability to survive at altitude without supplemental oxygen depends on general fitness, acclimatization, and genetics. In order to get used to the altitude (acclimitize) most climbers make multiple carries between pre established camps on the mountain and spending days at altitude to adjust to the low oxygen levels in the air.
Hypoxemic anoxia can be avoided by utilizing supplemental oxygen when in high altitudes and being aware of the early symptoms of altitude sickness and reducing altitude once recognized.
Supplemental oxygen works very well when used in appropriate situations.
The mountain is not said to be a techncal climb, it is the high altitude and lack of oxygen that makes it hard to climb.
Supplemental oxygen from portable or stationary tanks
As the altitude increases, the density of oxygen decreases.
No, the ratio of nitrogen to oxygen is not changed by altitude.
Lower air pressure means less oxygen. Means it's harder to keep your muscles supplied. You have to breathe faster and your heart has to pump faster
Not very well. The air is simply too thin- not enough oxygen. Mountain climbers at that elevation will need supplemental oxygen in order to breath. I get winded at 14,000 feet. Of course, if you are in an aircraft that has a pressurized cabin, you are being supplied with additional air.
Altitude sickness can be treated with oxygen therapy
Placing an oximeter on the baby's right hand or wrist is the best way to determine if a baby requires supplemental oxygen.
