Threshold of viability
The threshold of viability is the earliest point in pregnancy at which a baby can survive outside the womb with intensive care.
Summary
- UK guidance from 2019 allows active treatment to be considered from 22 weeks.
- The decision depends on the baby's individual risk and is made with the parents.
- Babies born this early who survive have a raised risk of lasting disability.
- It is separate from the 24 week limit in abortion law.
Interview questions
- A baby is about to be born at 22 weeks. Who should decide whether to attempt resuscitation?
- Should the abortion limit follow the threshold of viability?
