Hypoxia and hypoxemia facts. 1  Hypoxia is a condition or state in which the supply of oxygen is insufficient for normal life functions; hypoxemia is a condition or state where there is a low arterial oxygen supply â in some publications these terms are used interchangeably.
Hypoxia exists when there is a reduced amount of oxygen in the tissues of the body. Hypoxemia refers to a reduction in PO2 below the normal range, regardless of whether gas exchange is impaired in the lung, CaO2 is adequate, or tissue hypoxia exists. There are several potential physiologic mechanisms for hypoxemia, but in patients with COPD the predominant one is V/Q mismatching, with or without alveolar hypoventilation, as indicated by PaCO2.
