What is Fetal Viability?
One of the first things that a sonographer looks for in an early pregnancy ultrasound is the fetal heartbeat and a location of the pregnancy. Both of these are indicators as to the viability of the growing fetus. But what really does viability mean? Let’s talk about it!
Fetal Viability in Early Pregnancy
When the medical team is looking at the first ultrasound of a pregnancy, they always look for the location of the growing fetus. This is because a pregnancy should be growing within the uterus, which is the only place that can sustain it until birth. If a pregnancy is developing anywhere outside of the uterus, it is considered ectopic. An ectopic pregnancy is a serious medical condition that can cause a lot of damage to a woman’s body. Because an ectopic pregnancy does not have the ability to develop into a live birth, treatment is not considered an abortion and is legal everywhere despite the local abortion laws.
Understanding Fetal Viability: Age of Viability
Age of viability refers to the point in pregnancy when a baby has a reasonable chance of surviving outside the womb. Most experts agree this usually happens around 22 to 24 weeks of gestation, but it can vary depending on medical advances and individual circumstances. Viability is not a fixed moment; it shifts as doctors learn more about newborn care and develop better treatments.
Doctors determine viability by looking at the baby’s lung development, weight, and overall health. They use ultrasounds and other tests to see how well the baby is growing. Your healthcare team may also consider factors like infections or birth defects that could affect survival.
Factors That Affect Viability
Gestational age is the biggest factor in fetal viability. Every additional week in the womb helps the baby’s lungs, brain, and other organs mature. For example, a baby born at 23 weeks may face more risks than one born at 24 or 25 weeks. Fetal health and development vary from pregnancy to pregnancy. Babies with certain health conditions may need extra monitoring. For example, lung development is key. According to the American College of Obstetricians and Gynecologists, doctors may give medications to help speed lung growth if a preterm birth seems likely.
Maternal health also plays a role. Conditions like high blood pressure or diabetes can affect both mom and baby. Good prenatal care helps manage these conditions. A healthy mom tends to have a healthier baby, increasing the chance of survival if early delivery becomes necessary.
