A deficiency of oxygen in the blood; a condition where blood oxygen levels are abnormally low (American spelling of anoxaemia).
From Greek 'a-' (without) + 'oxys' (oxygen) + Latin 'haemia' (blood), using Latinate spelling conventions. Standard medical terminology in 20th century physiology and medicine.
Anoxemia is different from anoxia—anoxemia is low oxygen in your blood specifically, while anoxia is low oxygen in tissues. Doctors need both words to describe different problems in different places!
