oxygenrelated

Oxygenrelated is an adjective used to describe anything connected with oxygen, the third most abundant element in the universe and a major component of Earth's atmosphere. In science and engineering, oxygenrelated topics span chemistry, biology, medicine, environmental science and industry, including substances, reactions, and biological processes involving oxygen.

In chemistry, oxygenrelated topics include oxidation and reduction, formation of oxides and peroxides, and the role of oxygen in organic and inorganic reactions. Oxygen exists in several oxidation states and forms reactive species such as singlet oxygen and reactive oxygen species, affecting stability and potential damage.

In biology, aerobic metabolism uses oxygen to generate energy, while photosynthesis produces oxygen. Oxygen transport systems, such as hemoglobin, move O2 to tissues. Reactive oxygen species also participate in signaling and defense, with balance important to health.

In medicine, oxygenrelated concerns include oxygen therapy, measurement of blood oxygen (SpO2) and arterial gases, and devices for delivering oxygen. Risks include oxygen toxicity and increased fire risk in oxygen-rich environments.

In environmental science and industry, dissolved oxygen indicates water quality; oxygen is used in combustion and metal processing; and sensors and spectroscopy monitor oxygen-related phenomena. The term oxygenrelated is informal, used to flag materials, reactions, or processes that involve oxygen.
