        Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis: the ability to convert water and carbon dioxide into carbohydrates and wasteoxygen using solar energy. The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light.
    4. (medicine) A mixture of oxygen and other gases, administered to a patient to help thembreathe.
    5. (countable) Anatom of this element.
      • 2013, Spencer L. Seager, Michael R. Slabaugh,Chemistry for Today: General, Organic, and Biochemistry, page479:
        Look first at any structure to see if there is a carbon with twooxygens attached. Hemiacetals, hemiketals, acetals, and ketals are all alike in that regard.
    6. (figurative) A condition or environment in which something can thrive.
      Silence is theoxygen of shame.

        När pandemin tog fart våren 2020 var Region Västmanlands beredskap god när det gäller medicinska gaser som syrgas (oxygen). Redan i april 2020 fanns en extra tank flytandeoxygen på plats på sjukhusområdet i Västerås och man klarar i dag Socialstyrelsens skärpta krav.
        When the pandemic gained momentum in the spring of 2020, Region Västmanland's preparedness was good concerning medical gases likeoxygen. Already in April 2020, there was an additional tank of liquidoxygen in place at the hospital area in Västerås, and today they meet the stricter requirements set by the National Board of Health and Welfare.

    Usage notes

    [edit]
    • The termoxygen is rarely used; it primarily appears on gas tubes and canisters for international standardization, as well as a safety precaution to minimize the risk of confusingsyre(“oxygen”) withsyra(“acid”).
