Hypoxia

 

Hypoxia is a medical condition in which the body or a region in the body is deprived of sufficient oxygen supply at the tissue level. Hypoxia can either be generalised, which affects the entire body, or it can be local impacting a particular region. But sometimes during hypoventilation or rigorous physical exertion, there can be arterial variations in the concentration of oxygen as part of normal physiology. Hypoxia is different from anoxemia or hypoxemia. In hypoxemia, there is low arterial oxygen supply and in anoxemia, there is zero arterial supply of oxygen. But in hypoxia, the oxygen supply is insufficient. In anoxia, there is complete lack of the supply of oxygen. The symptoms of this condition depends upon the acceleration and severity of the onset. It is also referred to as hypoxiation.
