P00: Fetus and newborn affected by maternal conditions that may be unrelated to present pregnancy

P00.3: Fetus and newborn affected by other maternal circulatory and respiratory diseases

Certain conditions in the mother can damage the child's health during the pregnancy. The child’s health may be damaged by the mother having a circulatory disorder or respiratory tract disorder. As a result, the child in the womb may no longer get a proper supply of oxygen. The child may then not develop normally in the womb. This can also lead to a premature birth. The child is then born before the end of the 37th week of pregnancy. After the birth, problems can also occur with the child's breathing, circulation or nervous system.
