is 5 liters of oxygen a lot?

A 2 liter per minute rate is quite common in adults, although when there is severe shortness of breath, the rate is increased to 3, 4 or 5 liters/minute in some cases. It is very important to follow the physician's orders about how much oxygen to given per minute.

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.

1mole of O₂ gas contains 2 x Avogadro number of atoms of oxygen. ∴ 5.6 litres of Oxygen gas contains 3 x 10²³ oxygen atoms.

The percent of oxygen is actually the same at all altitudes, 21%; however, it is 21% of a smaller number as one goes higher. The barometric pressure at sea level is 760 mmHg, and at 10,000 ft, it is 534 mmHg.

The minimum dissolved oxygen concentration for healthy growth, tissue repair and reproduction in koi is 6 mg per liter of water, but ideally the concentration should be higher. An oxygen level over 7 is desirable, and any reading above that should be considered excellent.

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.

While normal atmosphere contains between 20.8 and 21 percent oxygen, OSHA defines as oxygen deficient any atmosphere that contains less than 19.5 percent oxygen, and as oxygen enriched, any atmosphere that contains more than 22 percent.

The atmospheric concentration for oxygen is 21% but the minimum required for humans is about 17%, so only a little less than 1/4 of the atmosphere would have to be respirated before the concentration could not support humans.

As a rule of thumb, the nasal cannula delivers 24% of oxygen at one liter, with an increase of 4% of oxygen for each additional liter flow.

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.

D. At STP (standard temperature and pressure), an ideal gas occupies 22.4 liters per mole. Here we have 48 g of oxygen gas or O2, each molecule of which consists of two atoms of the oxygen element. Since oxygen (O) has an atomic mass of 16 g, oxygen gas (O2) has a molecular mass of 2 x 16 = 32 g.

To support the absorption of oxygen and release of carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter (about three tenths of a quart) of oxygen is transferred from the alveoli to the blood each minute, even when the ...

At standard conditions, 1 liter of air at 21% oxygen possesses 0.21 L of oxygen. Since at STP 1 mole of gas occupies 22.4 L, simply divide 0.21/22.4, to arrive at 0.0094 moles of oxygen.

Well, a liter is about 1 kilogram (1 kg) mass of water at normal temperature and pressure. At Earth sea level conditions, a kg is attracted, also known as weight, of about 2.2 pounds per liter. So 5 liters is 5 liters X (2.2 lbs/liter) = 11 lbs = 48.9 newtons weight.

Normal and low blood oxygen levels A normal blood oxygen level varies between 75 and 100 millimeters of mercury (mm Hg). A blood oxygen level below 60 mm Hg is considered low and may require oxygen supplementation, depending on a doctor's decision and the individual case.

The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount. The volume of oxygen is reduced by a small amount, 4% to 5%, compared to the oxygen inhaled. The typical composition is: 5.0–6.3% water vapor.

An average person will breathe 0.5 (liters/breath) x 15 (breaths/minute) x 35,344,512 (minutes/lifetime), which equals 265,083,840 liters/lifetime. More or less 265 million liters of air.
