Because they find themselves in environments of little or no oxygen, and oxygen is essential to life.
We carry oxygen cylinders while climbing a mountain to supplement the decreasing levels of oxygen at higher altitudes. This helps prevent altitude sickness and ensure that the body receives enough oxygen to function properly.
Sickle cell hemoglobin can carry one oxygen molecule.
Arteries carry blood high in oxygen away from the heart to the rest of the body. The blood in arteries is oxygenated, while veins carry blood low in oxygen back to the heart.
Oxygen is quite important for the continued functioning of the human body.Normally, we get it from the air that's always around us. In just the past 50years or so, it became possible for humans to travel to places above the Earth'ssurface where there's no air. Since we are so intelligent, clever, quick, andsmart, we immediately made the connection with places we've already beenwhere there's no air, like under the surface in swimming pools, bathtubs, andoceans, and realized that when we go to the new places, we need to take airwith us. That's the main reason for the cylinders, masks, helmets, and most ofthe other equipment you see in the vicinity of astronauts' noses.
The protein in blood that helps carry oxygen is called hemoglobin. Hemoglobin is located within red blood cells and binds to oxygen in the lungs, transporting it to tissues throughout the body.
Mountaineers carry oxygen cylinders at high altitudes to supplement the reduced oxygen levels in the air. This helps prevent altitude sickness, improves physical performance, and reduces the risk of life-threatening conditions such as hypoxia and cerebral edema.
It is because at high altitudes the oxygen is not sufficient..........
At extreme altitudes, the air becomes rarefied and has a very low oxygen concentration. This can lead to a condition known as hypoxia, which is deprivation of oxygen to the brain, which can cause loss of consciousness, paralysis, and death.
Because at great heights ie up mountains the air becomes 'thinner' this means there is less oxygen and so it is harder to breathe. So they carry the oxygen so that they can continue up the mountain otherwise they will be unable to coninue because it is dangerous.
A climber carries an oxygen cylinder on their back because it helps him/her to breathe easier. On high altitude mountains like Mount Everest the air is so thin it makes it very hard for anyone to breathe without extra oxygen from a cylinder.
because the higher you go up a mountains are the less oxygen there is.
Mountaineers condition themselves by expanding their lungs. They carry oxygen on climbs to altitudes where it will be needed.
The higher you go up away from the Earth's surface, the less oxygen can be found in the air and more of gases we don't need to breathe in. So, as the mountaineer goes higher up, breathing becomes harder and your body works slowly, reducing reaction times. By carrying an oxygen tank, the mountaineer can always be breathing the perfect concentration of oxygen they need at all times.
We carry oxygen cylinders while climbing a mountain to supplement the decreasing levels of oxygen at higher altitudes. This helps prevent altitude sickness and ensure that the body receives enough oxygen to function properly.
So that they may breath underwater.
Mountaineers carry oxygen cylinders with them on high altitude mountains like Mount Everest. This is because the higher the mountaineer climbs the less air there is to breathe.When you travel in an aeroplane at a high altitude the plane will be pressurized. A cabin air pressure at cruising altitude is lower than air pressure at sea level. At typical cruising altitudes in the range 11 000-12 200 m (36 000-40 000 feet), air pressure in the cabin is equivalent to the outside air pressure at 1800-2400 m (6000-8000 feet) above sea level.
Ambulances carry oxygen cylinders because it is often used to revive people, e.g. For people rescued from drowning or people rescued from smoke filled rooms.Hospitals also use it for patients with breathing difficulties e.g. asthma.
