A “viable pregnancy” after 22-24 weeks is a pregnancy when there is a chance that if delivered the baby can survive.

What is considered fetal viability?

The limit of viability is the gestational age at which a prematurely born fetus/infant has a 50% chance of long-term survival outside its mother’s womb. Currently, the limit of viability is considered to be around 24 weeks, although the incidence of major disabilities remains high at this point.

What is considered a non viable fetus?

What causes a fetus to not have a heartbeat?

Can a baby survive at 20 weeks?

Babies born after only 20 to 22 weeks are so small and fragile that they usually do not survive. The chance of a baby surviving if they are born at 22 weeks of a pregnancy is only 10-20%. This means that if 10 babies are born this early, 8 babies will die, and only 1 or 2 babies will survive.
