Mechanism of action. Oxygen therapy increases the arterial pressure of oxygen and is effective in improving gas exchange and oxygen delivery to tissues, provided that there are functional alveolar units.
How does oxygen therapy help with cellular oxygenation?
Oxygen therapy improves effective cellular oxygenation , even at a low rate of tissue perfusion. Oxygen molecules adjust hypoxic ventilatory drive by acting on chemoreceptors on carotid bodies that sequentially relay sensory information to the higher processing centers in brainstem. It also attenuates hypoxia-induced mitochondrial depolarization that generates reactive oxygen species and/or apoptosis. Studies investigating on hyperbaric oxygen therapy has shown that oxygen supplementation can induce neural stem cell proliferation in neonatal rats thus promoting neurological regeneration after injuries 3. CD34+, CD45-dim leukocytes are also potential targets for hyperbaric oxygen therapy benefit as their mobilization was increased in vitro which could facilitate the acceleration of recovery at peripheral sites 1.

What happens when detonating gas is ignited?
When detonating gas is ignited a large explosion takes place: with the combination of oxygen and hydrogen, water forms, and a high temperature develops. Water vapor expands greatly with the surrounding gases, and pressure becomes high, in which not only a fragile cylinder can explode, but also a more durable vessel. For this reason, you should be extremely careful when working with detonating mixture.
What is hydrogen oxidize?
Hydrogen oxidizes to water. On the walls of the cylinder, drops of condensed water vapor gradually settle. For the oxidation of 2 molecules of hydrogen, 1 molecule of oxygen is used, and 2 water molecules form; the equation of the reaction is: 2Н₂ + O₂ → 2Н₂O.
How does oxygen gas burn?
Then put a pipe with hydrogen under the cylinder. The hydrogen, which is lighter than air, will completely fill the cylinder. Ignite the hydrogen around the open part of the cylinder, and insert a glass pipe into the cylinder, through which oxygen gas flows. Around the end of the pipe, the flame will blaze up, while a flame will calmly burn inside the cylinder filled with hydrogen. In the course of the reaction, it is not the oxygen that burns, but the hydrogen in the presence of the small amount of oxygen coming out of the pipe.
How much less oxygen is in air?
Air contains five times less oxygen than pure oxygen in the same volume. In air, oxygen is mixed with a large amount of nitrogen – a gas that does not burn itself and does not support combustion.
Does oxygen go out of the flame?
As soon as the supply of oxygen increases so much that it does not manage to burn completely, part of it goes outside the flame, where mixtures of hydrogen and oxygen form, and small individual sparks appear, resembling explosions. A mixture of oxygen and hydrogen is known as detonating gas.

Why does water become oxygen saturated?
Algae and plants in the surface layers work oppositely. They produce a high amount of oxygen at high temperatures, causing the water to become oxygen saturated.
How does oxygen dissolve in water?
As was described earlier, oxygen dissolves naturally when water comes in contact with air. Oxygen is also applied commercially. For industrial purposes the element is extracted from air by about 100 million tons annually. Of the total amount, 55% is applied in steel production, 25% is applied in chemical industries, and the remainder is applied in hospitals, for starting missiles, and for slicing metal. In chemical industries a reaction of oxygen and ethylene is applied, and the resulting ethylene oxide is applied as an antifreeze and polyester. Oxygen is highly reactive, and can therefore be applied to break down hazardous substances. It may also be applied as a bleach. Oxygen in ozone compounds is applied for drinking water disinfection. Waters are not contaminated by oxygen when it is applied industrially.

Toxicity
- Oxygen atoms can be found in a number of toxic organic and inorganic compounds. Toxic compounds are for example hyper oxides and peroxides. Some substances are toxic under low oxygen conditions in water, because breathing of organisms increases and consequently substances are absorbed more rapidly. For obligatory anaerobic organisms, high oxygen concen…
Environment
- Ozone is an environmental pollutant when it is present in the troposphere. In the stratosphere it functions as a protective layer that reflects solar UV-radiation. Without this ozone layer, life on earth would be impossible. A number of plant species are susceptible to high ozone concentrations in air. This does not show as visible stress symptoms, but rather as growth limit…

The oxygen atom is a part of hydroxyl, carbonyl, and other functional groups. It is transported through blood bound to haemoglobin, and is subsequently stored in muscles in myoglobin. The presence of ox…
Effects
- When air contains a lower than 3% oxygen concentration, death by asphyxiation generally follows. At a lower than 7% concentration, one may loose consciousness. Too much oxygen may be lethal. Sports divers that breath pure oxygen often get cramps. Baby's that receive too much oxygen in incubators, generally grow blind.
Definition
- The often applied BOD5 value indicates the oxygen concentration applied by micro organisms within five days at 20oC in an aerobic environment, to convert organic matter to carbon dioxide, water and new biomass. It is expressed as mg O2 per litre of wastewater. Multiplying this number by the wastewater volume gives the amount of hazardous substances. The BOD5 per unit of tim…
