Compressed oxygen holds oxygen in a metal cylinder (tank) under pressure. Oxygen is a colorless, odorless and tasteless gas. The gas is capable of generating temperatures of 3000 C and 2800 C. This is required for oxy-hydrogen and oxy-acetylene blow torches. In extreme cases, seizures or death occur. Long term exposure may cause ocular or pulmonary problems. Keep a working fire extinguisher in your home where it is easy to get to. It is also used in reducing metal ores. Industries use the gas for cutting, welding and melting metals. This allows humans and animals to perform their daily activities. It has no smell or color. The medical uses of oxygen involve supplying it in packed cylinders to help patients, who find it difficult to breathe, or it is used by mountaineers at high latitudes, underwater divers, astronauts walking in space, etc. In its natural form it is all over the atmosphere. Oxygen is found in the atmosphere, the human body, the sun and oceans. Turn off the oxygen system when it is not being used. 1. This gas is used in water treatment and chemical combustion. Compressed oxygen tanks are heavy, and are meant to be used when you stay mostly in … It is also important to point out to the students that a lack of oxygen or breathing pure oxygen is detrimental to our health. Widespread cell death in the same area leads to tissue death, or necrosis. Oxygen is a tasteless gas. The role of oxygen in the human body cannot be exaggerated. Lungs take in oxygen for the combustion of food and they eliminate the carbon dioxide produced. It is used to make acids, sulfuric acid, nitric acid and other compounds. The main specific uses of oxygen are best summarized by separating them into the three convenient categories referred to above. It is also used in airplanes and cars. This breathing apparatus is also used by astronauts walking in space, scuba divers and mountaineers. Keep the oxygen container upright. Oxygen can be used to make compounds with all elements minus inert gasses. Oxygen bars are establishments found in the United States since the late 1990s that offer higher than normal O 2 exposure for a minimal fee. Of all the uses of oxygen, sustaining life is the most important. Your doctor may have you do some tests to see how well your lungs work. At 50%, toxicity will occur. Oxygen, as a mild euphoric, has a history of recreational use in oxygen bars and in sports. Humans need oxygen to provide nutrients to all of the cells in their bodies. Oxygen is a colorless, odorless gas. In healthcare institutions like hospitals, oxygen supplies are kept in stock. Other symptoms will manifest. They use the Sun's light to get hydrogen from water, giving off oxygen. Do not smoke and do not allow others to smoke near the oxygen. A high temperature flame is used to melt them by heating the junction. The large volume of gaseous oxygen resulting from the vaporization of liquid oxygen has the potential, if trapped in a closed circuit not adequately protected by pressure relief devices, to generate gas pressures high enough to cause explosive rupture of containers, transfer lines, piping, and other system components. As the evidence behind the current trauma guidelines with regard to oxygen therapy is not clear, and excessive oxygen administration has been found to be harmful in other patient populations, we sought to perform a systematic review to identify and summarise the evidence for the use of supplementary oxygen for spontaneously breathing trauma patients, and the use of high (0.60–0.90) … This can occur when air oxygen is higher than 21%. Swedish chemist Carl Wilhelm discovered the tasteless, odorless gas in 1772 after he experimented, heating … Its most reactive variant is ozone O3. Be the first to answer! Algae, cyanobacteria and plants make the Earth's oxygen gas by photosynthesis. Even for the food and liquid demanded by the body, the only way it becomes useful is through oxidation . BOD means biological oxygen demand and COD means chemical oxygen demand. Toxicity can be due to elevated oxygen levels or other causes. This is because the diver takes in more oxygen than usual. Symptoms include twitching, dizziness and nausea. In addition to helping prevent heart failure in people with severe lung diseases, such as COPD, supplemental oxygen has many benefits. ATP is a molecule that supplies cells with energy. An Oxygen Specialist can explain to you the differences between both and can work with you and/or your uncle to determine which portable oxygen concentrator is right for his oxygen therapy needs.
