Your friend tells you that her baby was dubbed a "blue baby" by hospital staff and that it was born with a "hole in its heart". Provide an explanation to your friend of this phenomenon
A fetus has reduced need for blood flow to the lungs, since the lungs are not yet functional in terms of gas exchange. A fetal modification called foramen ovale provides a direct connection between the right and left atria, thereby allowing blood to more directly enter the systemic circuit. If this bypass persists after birth, there is reduced systemic blood flow which results in cyanosis.
