Oxygen cutting involves adding oxygen to a cutting gas to increase the heat and fine-tune the flame for desired effects. It is a popular method for cutting and welding metal structures where electrical power is not available. Oxygen also saves gas and makes the flame burn hotter. The oxygen cutting torch is adjusted by regulating […]
A pulse oximeter measures oxygen saturation in the blood by sending light through a finger or earlobe. A reading between 96-100% is normal, while below 96% indicates hypoxia. However, the device may not be accurate in certain situations, and physical signs of hypoxia should also be evaluated. Normal oxygen saturation can be determined using a […]
Oxygen saturation levels refer to the amount of oxygen in red blood cells. Normal levels vary with age and activity, but levels below 90% are considered abnormal and can cause symptoms such as shortness of breath and confusion. Oxygen saturation can be measured with a pulse oximeter or arterial blood gas test, and low levels […]
Oxygen is essential for animal life and measuring pulse oxygen levels can help establish physical health. Hemoglobin levels are important in measuring oxygen pulse, and pulse oxygen sensors use light rays to take measurements. Abnormal levels can signal health problems, but some conditions may misrepresent readings. Oxygen is perhaps the most crucial element in building […]
Half of the Earth’s oxygen comes from the oceans, where photosynthesizing microorganisms called phytoplankton contribute 50-85% of the oxygen in the atmosphere through photosynthesis. Phytoplankton are too small to see but are noticeable as colored spots on water surfaces. While we usually think of jungles and rainforests like the Amazon as the “lungs” of the […]
Oxygen is a highly reactive and abundant element essential for many chemical processes on Earth. It exists as a gas, liquid, and solid, with diatomic oxygen being the most common allotrope. Oxygen’s electronegativity and ability to form compounds make it important for life and combustion reactions. Oxygen is among the most abundant and important elements […]
An oxygen deficit can be caused by exercise or lung disease and can lead to medical problems, including brain damage and organ failure. Treatment options vary depending on the cause and may include rest, medication, lifestyle changes, or supplemental oxygen. Doctors, including pulmonologists, are involved in diagnosing and treating patients with this problem. An oxygen […]
Oxygen is a vital gaseous element for respiration and is widely distributed on Earth and in the universe. It can be extracted through fractional distillation and has various uses in medicine, welding, and industry. However, pure oxygen can be dangerous and toxic, causing damage to the lungs and cells. Oxygen is a colourless, odorless and […]
The basic oxygen furnace is used to purify pig iron into molten steel by oxidizing impurities and adding oxygen. The furnace is lined with alkaline refractory materials and loaded with scrap steel and pig iron. Oxygen is blown through the mixture, creating a chemical reaction that raises the temperature and creates slag. The purified steel […]
Respiratory hypoxia is a medical condition caused by insufficient oxygen supply to the body or a part of it. There are four types: hypoxic, stagnant, anemic, and histotoxic. The causes, signs, and treatment depend on the type of hypoxia. Respiratory hypoxia is a medical condition that occurs when the body or a part of the […]
Breathing in too much pure oxygen can cause oxygen toxicity, resulting in symptoms such as nausea and airway inflammation. Central nervous system damage occurs at high pressure, while long-term exposure at normal pressure can lead to lung or eye problems. Divers are particularly at risk. High oxygen levels produce highly reactive byproducts that can damage […]
Oxygen injection promotes the growth of beneficial aerobic bacteria in sludges and liquids. It is used in wastewater treatment and environmental remediation to speed up the bacteria’s job. The process introduces no harmful byproducts and can be rented or purchased by environmental cleanup companies. Oxygen injection is a technique used to promote the growth of […]
The sun doesn’t burn like fire because there is no oxygen in space. Instead, the sun’s heat and light come from nuclear reactions inside it. In the future, the sun will become a “red giant” and run out of energy. Most of us learned in school that there are three components needed for fire: fuel, […]
