He virtually condemned us all to death. Chances of survival following preterm birth
Medical advances mean that we are getting better at treating preterm babies but the chances of survival still depend on gestational age (week of pregnancy) at time of birth.
* Less than 22 weeks is close to zero chance of survival * 22 weeks is around 10% * 24 weeks is around 60% * 27 weeks is around 89% * 31 weeks is around 95% * 34 weeks is equivalent to a baby born at full term.
