Hypoxemia - Definition

Ask a question


Hypoxemia manifests as oxygen deficiency in the blood. This typically results in a poor connection between the blood capillaries and lung alveoli. Hypoxemia leads to hypoxia, a decrease in oxygen supply to the tissue by the blood, or tachycardia, which signifies an abnormal acceleration of the heart's rhythm. The principal causes of hypoxemia are pneumonia, emphysema, pneumopathy, anemia, and blocked airway.
