Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

O

Pure oxygen is mainly used to speed the shallow decompression stops at the end of a military, commercial, or technical dive. Risk of acute oxygen toxicity increases rapidly at pressures greater than 6 metres sea water. It was much used in frogmen’s rebreathers, and is still used by attack swimmers.

Pure oxygen can be deadly. Our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called haemoglobin. If you breathe air with a much higher than normal O2 concentration, the oxygen in the lungs overwhelms the blood’s ability to carry it away.

Oxygen is found naturally as a molecule. Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2. Oxygen is normally found as a molecule. It is called dioxygen.

Do You Need a Prescription for Oxygen? Although we all breathe oxygen, medical oxygen is highly concentrated and qualifies as a medical substance. As such, the United States Food and Drug Administration (FDA) requires a prescription before you can obtain your supplemental oxygen.

Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous.

Can you breathe welding oxygen? No. You should not breathe welding oxygen. Medical oxygen is certified to contain a stable percentage of oxygen below a strict threshold of impurities.

Symptoms of low blood oxygen levels

• shortness of breath.
• headache.
• restlessness.
• dizziness.
• rapid breathing.
• chest pain.
• confusion.
• high blood pressure.

The amount of oxygen that you breathe in a day is estimated to The amount of oxygen that you breathe in a day is estimated to be about 7.2 kilograms. That totals about 11,000 liters of air per day. Therefore, about 5-percent of breathed air is consumed in each breath.

On average, canned oxygen costs just under $50 a unit. That might not seem like much, unless you intended to use canned oxygen regularly. If you did, your cost would exceed $1,160 per day if you relied on canned oxygen for constant use, and more than $426,000 a year.

Its worth is over 20 million naira while an Oxygen cylinder could be sold for 30 thousand naira. This is not a cheap commodity as compared to the conventional gas cylinders that go for a price range of 3 thousand to 5 thousand naira in the market.

Oxygen cylinders Cylinders provided at home in the United Kingdom contain 1360 l of oxygen, which provides 11 hours of treatment at a flow rate of 2 l/min.
