What is the difference between oxygen and air?

Most critically ill patients need oxygen, and some pregnant women need to take oxygen frequently. What is the difference between oxygen and ordinary oxygen produced by household oxygen generators? Is it really that we think oxygen generators? The oxygen does not help the body? In fact, things are not what we think, oxygen generators are very useful at certain times.

Speaking of here, we must first spread the basic knowledge. The air we breathe everyday is a mixed gas, which is a mixture of various gases. Calculated according to the composition of the air volume, it is about: 78% nitrogen (about 4/5 of the volume of air), 21% oxygen (about 1/5 of the volume of air), rare gas accounts for 0.94%, carbon dioxide and other Gas and impurities account for only 0.03%. It can be seen that our daily air is mainly nitrogen, supplemented by oxygen. The mixing ratio will also change accordingly due to environmental factors. The most relevant to our daily life is the plateau climate. When we reach high altitudes, due to the pressure drop, the oxygen content we need will decrease, causing the phenomenon of plateau hypoxia.

The oxygen produced by the household oxygen system is mainly composed of oxygen and traces of other gases. This allows oxygen to reach 90% of the gas produced, which is several times higher than our normal air content. This provides a better source of gas for those who need oxygen, and increases the amount of oxygen saturation in the body. Allowing the patient to breathe less gas can get more utility. This is also the reason why high concentrations of oxygen are used in medicine.

From the above comparison, we can know that the biggest difference between the oxygen produced by the oxygen generator and the ordinary air is the difference in oxygen concentration, and no new gas is produced. Hope everyone have a correct understanding.
