Everyday Uses of Oxygen

Oxygen is an amazing substances that also has a variety of applications in our every day lives.

•    Every living creature and plant requires oxygen to survive.
•    Oxygen therapy is prescribed for patients diagnosed with chronic obstructive pulmonary disease (COPD) as well as other medical conditions, that require oxygen to be administered at home to aid in the treatment of that condition. The use of pressurized oxygen therapy has also provided outstanding medical benefits.
•    Oxygen is a standard treatment for many patients that find themselves in hospital, which have a huge supply on site.
•    The production of steel is reliant upon oxygen where it is used in a blast furnace to turn carbon into carbon dioxide, which reduces the iron oxides to pure iron.
•    Oxygen is also used in torches for cutting and welding. Oxygen reacts with hydrogen in which it can heat to over 5,000 degrees. These torches can cut through or weld together most metallic substances.
•    As a liquid, oxygen is used widely both medically and industrially, most commonly as an oxidizing agent for use in missiles and rockets where it reacts with liquid hydrogen to produce the thrust for take-off. Astronauts’ spacesuits have close to pure oxygen.
Chemical Synthesis:
•    Hydrocarbons are broken apart by heating them with oxygen. This method is used to induce combustion in order to produce water and carbon dioxide. Also if the mixture is controlled it can break apart the hydrocarbons to produce acetylene, propylene and ethylene.
•    Oxygen is also used at plants that treat sewage or purify water. Oxygen is pumped through water to increase the production of natural bacteria, which break down waste products.
•    Oxygen as a gas is required to produce energy in industrial processes, generators and ships and it is also used in airplanes and cars.

How Portable Oxygen Concentrators Work

The air around you contains about 80 percent nitrogen and 20 percent oxygen. If you require the use of portable oxygen to aid with a medical problem then you require a much higher percentage level of oxygen which can be delivered straight to your lungs by portable/at home devices. One such device is an oxygen concentrator.
How They Work:
Your oxygen concentrator takes in air from the surroundings and splits the oxygen from the nitrogen. It then releases the nitrogen back into the surrounding air. The concentrator collects and stores the oxygen and then dispenses it back to the patient.
As long as you have it running and set properly, your oxygen concentrator is continually “making” 90 – 95 percent pure oxygen out of normal air, so you’ll have all you need.
Oxygen tanks are already pre-filled with oxygen and have to be re-filled whereas concentrators can make oxygen as it goes. Tanks also run the risk of leakage, which can cause explosions/fires and are heavier and more difficult to move around with.
Concentrators do not pose any danger and the other main benefit is mobility. Most of the concentrators are portable, which means they’re designed to be used at home, on the go and even on a plane, therefore you’ll always have all the oxygen you need, no matter where you are.
Concentrators also have the option of pulse-dose or continuous administration. Pulse-dose is a newer oxygen therapy technology that delivers oxygen through your cannula only when you breathe in. Continuous flow oxygen is constantly flowing through the tubes.
You should talk to your doctor about which dosing method is right for you. Pulse-dose technology can be delivered in a smaller size and will allow for longer battery life. Alternatively, most patients who require oxygen for sleep, use a continuous flow dosage due to shallow night breathing. Sometimes it’s necessary to use continuous flow oxygen while you sleep and pulse-dose oxygen during the daytime.
