Hypoxia occurs when the tissues in the body do not receive enough oxygen. The symptoms of hypoxia vary with the individual. Hypoxia can be caused by several factors, including an insuffi-cient supply of oxygen, inadequate transportation of oxygen, or the inability of the body tissues to use oxygen. The forms of hypoxia are divided into four major groups based on their causes; hypoxic hypoxia, hypemic hypoxia, stagnant hypoxia, and histotoxic hypoxia.
