Due to the rise in medical standards, preterm babies at 30 weeks of gestation are able to survive in most cases, but due to the fact that fetuses at this stage have less body fat and immature lungs, there is a very small probability that preterm babies will not be able to survive if they are combined with lung infections and other diseases. Although the organs of the fetus at 30 weeks of gestation are well developed, the fetus is unable to maintain a normal body temperature due to low body fat; the lungs are also immature and unable to breathe normally, but the survival rate of preterm infants at 30 weeks of gestation has been greatly improved by the use of incubators and reagents to promote fetal lung maturation. A small number of preterm infants may not survive if they are born with severe cardiopulmonary dysfunction. Preterm birth at 30 weeks of gestation is recommended to be transferred to an institution that has the capacity to treat preterm infants in order to avoid accidents.
