hy·pox·e·mi·a

(hī'pok-sē'mē-ă)
Subnormal oxygenation of arterial blood, short of anoxia.
Synonym(s): hypoxaemia.
[hypo- + oxygen, + G. haima, blood]

hypoxaemia

Deficiency of oxygen in the blood. This is usually due to relative failure of the passage of oxygen from the atmosphere to the blood because of lung disease, or inadequate or inappropriate movement of blood through the lungs because of heart disease, either congenital or acquired. Hypoxaemia often causes CYANOSIS.

hypoxaemia

lower than normal oxygen tension ( P O2) in the arterial blood, therefore lower than normal saturation of haemoglobin and oxygen content per unit volume. See also oxyhaemoglobin dissociation curve.
