What is liquid oxygen?
The Race Club World Team swimmers have used a product we now have available for sale called Liquid Oxygen. We have used this product since 2000 and believe that has a beneficial effect on athletic performance. So what is it? First of all, it is not truly liquid oxygen, but rather oxygen gas suspended in a liquid. Most people believe that the only way humans can get oxygen to the cells is through the lungs. After all, we are not fish with gills. Well, not quite. Actually, we do have the capability of absorbing oxygen through our mucous membranes (under the tongue and in the gastrointestinal tract) in small quantities. Most of the oxygen transported to our cells arrives via the hemoglobin molecule contained within the red blood cell. However, the part of the blood that is not red blood cells, called the plasma, is also capable of carrying oxygen and may transport as much as 5% of the available oxygen to the cells. Studies have shown that the absorption of oxygen through mucous membranes
As is evident by its name, liquid oxygen is oxygen in its liquid form. Liquid oxygen is derived by distilling liquid air, which consists of about 19 percent oxygen, 80 percent nitrogen, and small amounts of inert gases like argon, krypton, and xenon. Liquid air, in turn, is derived by rapidly expanding pressurized gaseous air, which has been first purified in order to remove the carbon dioxide and other substances that have high points, such as hydrocarbons, which may hamper the expansion process. The liquid oxygen obtained from this is pale blue in color and has paramagnetic as well as cryogenic properties. As far as commerce is concerned, liquid oxygen is categorized as an industrial gas and is used widely for medical and industrial purposes. Since the expansion ratio of liquid oxygen is 860:1, it is used in military and commercial aircraft these days. Liquid oxygen is also commonly used as a liquid oxidizer propellant in rockets, generally in combination with kerosene or hydrogen. B
