WebNational Center for Biotechnology Information WebMar 13, 2024 · Hypoxemia is defined as an abnormally low level of oxygen in the blood (ie, low partial oxygen tension [eg, PaO 2 <60 mmHg]). Hypoxia is defined as a condition where the oxygen supply is inadequate either to the body as a whole (general hypoxia) or to a specific region (tissue hypoxia).
