Oxygen levels start to decrease significantly at altitudes above 8,000 feet (2,400 meters), leading to the condition known as hypoxia. At higher altitudes, such as above 12,000 feet (3,600 meters), individuals may require supplemental oxygen to prevent altitude sickness and other health complications related to the thin air.
The Earth's crust is made up of solid rock that is relatively thin in comparison to the rest of the Earth's layers. It is composed mainly of silicate minerals like feldspar and quartz, with the two most abundant elements being oxygen and silicon.
Connecting a high flow of oxygen to the oxygen inlet on a pocket mask can deliver up to 50-60% oxygen concentration. The exact percentage may vary based on the oxygen flow rate, the patient's breathing pattern, and the mask's design. It is commonly used in emergency situations to provide supplemental oxygen to patients.
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.
Oxygen is not scarce in the Earth's atmosphere, as it makes up about 21% of the air we breathe. However, access to oxygen can be limited in certain conditions such as high altitude, underwater, or in enclosed spaces with poor ventilation.
In higher altitudes, the air pressure decreases, leading to lower oxygen levels. This means there are fewer oxygen molecules available for breathing, making it harder for our bodies to function optimally.
Blood picks up oxygen in the lungs when it diffuses across the thin walls of the alveoli into the bloodstream. This oxygen is then carried by red blood cells to tissues throughout the body.
they start at the bridge and make their way up to the head, thick to thin , low E than A , D, G, B than high E.
Because of high altitude sickness which is affected by climbing up high were there is high altitude. High altitude is were there is to much oxygen up high, if you breech in to much oxygen you could faint.
When the start-up cost is high
Climbers need to wear oxygen masks to help them breathe as the air is thin higher up Mount Everest than at sea level.
Callisto is surrounded by an extremely thin atmosphere composed of carbon dioxide and probalby molecular oxygen
because your way up high and their is not much atmosphere in the trophosphere and statoshpere so it could help wearing a mask to have to brethe! heavy clothes? not much gravity you need to weigh more then the usual on mountains or it will be so far but so close related to the moon!
Ganymede, Jupiter's moon, has a thin atmosphere composed mostly of oxygen and hydrogen. These gases are present in very low concentrations compared to Earth's atmosphere. Ganymede's tenuous atmosphere is believed to be created by charged particles interacting with the moon's surface.
The pulmonary vein carries blood from the lungs back to the heart, and it has a high oxygen content because the blood picks up oxygen in the lungs during gas exchange.
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
The summit is so high up, therefore the air is very thin.
Mercury's atmosphere is very thin, consisting mainly of oxygen, sodium, hydrogen, and helium. It is around 100-trillion times less dense than Earth's atmosphere.
