What is meant by viability in pregnancy?

What is meant by viability in pregnancy?

According to Websters Encyclopedic Unabridged Dictionary of the English Language, viability of a fetus means having reached such a stage of development as to be capable of living, under normal conditions, outside the uterus.

Considering this, what week is viability in pregnancy?

In general, infants that are born very early are not considered to be “viable” until after 24 weeks gestation. This means that if you give birth to an infant before they are 24 weeks old, their chance of surviving is usually less than 50 percent. Some infants are born before 24 weeks gestation and do survive.

Secondly, can a baby survive at 20 weeks if born? Babies born after only 20 to 22 weeks are so small and fragile that they usually do not survive. Their lungs, heart and brain are not ready for them to live outside the womb. The chance of a baby surviving if they are born at 22 weeks of a pregnancy is only 10-20%.

Similarly, you may ask, how do I know my pregnancy is viable?
