Altitude-Oxygen Chart. Use the tables below to see how the effective amount of oxygen in the air varies at different altitudes. Although air contains 20.9% oxygen at all altitudes, lower air pressure at high altitude makes it feel like there is a lower percentage of oxygen.

Being confined to an oxygen-deficient environment for a prolonged period of time can even prove fatal. The air we breathe normally contains about 21 percent oxygen.

Humans need oxygen to live, but not as much as you might think. The minimum oxygen concentration in the air required for human breathing is 19.5 percent. The human body takes the oxygen breathed in from the lungs and transports it to the other parts of the body via the body's red blood cells.

Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.

We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth's atmosphere.

Many oxygen bars use a concentrator, which filters out the nitrogen and other gases in the air circulating in the room, and then delivers the concentrated oxygen, about 95 percent pure, through a hose at a continuous flow rate.

Exhaled air at sea level contains roughly 13.5% to 16% oxygen. The oxygen metabolised is generally about 4% to 5% of the inspired volume at normal atmospheric pressure , or about 20% of the available oxygen in the air at sea level . Exhaled air at sea level contains roughly 13.5% to 16% oxygen.

The average adult, when resting, inhales and exhales about 7 or 8 liters of air per minute. That totals about 11,000 liters of air per day. Inhaled air is about 20-percent oxygen. Exhaled air is about 15-percent oxygen.

Inhaled air is by volume 78.08% nitrogen, 20.95% oxygen and small amounts of other gasses including argon, carbon dioxide, neon, helium, and hydrogen. The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount.
