Hypoxia (hypoxiation or anoxemia) is the condition of reduced oxygen content. Postnatally, environmental hypoxia can effect the function/survival of many systems, while prenatal hypoxia (including birth) has been shown to have many detrimental effects for the growing fetus/neonate. It should be noted that normal prenatal development typically occurs in an environment that is hypoxic compared to the maternal or postnatal environment. The hypoxia discussed here refers to reduced maternal oxygen or fetal hypoxia below that occurring in normal development. Exposure to altitude hypoxia normally results in physiological responses that act to preserve maternal and fetal oxygenation.
Maternal smoking, in addition to vasoconstriction, has associated carbon monoxide inhalation that has also been suggested to interfere with delivery of oxygen to the fetus. (More? Smoking)
Historically, hypoxia was identified in growing mice and rats as influencing the growth of caudal vertebrae. More recently hypoxia has now been shown to influence many different developing systems including neural, heart and skeletal systems.
