Introduction
A premature infant refers to a baby born before reaching 40 weeks of gestation. Generally, by about 28 weeks of development, most organs are sufficiently mature. If delivered at 28 weeks, the infant can survive; however, if delivered at 21 weeks, vital organs such as the heart and lungs are not well-developed, resulting in a lower survival rate. With timely medical treatment, good immune resistance, and appropriate care and supportive measures, there is still a chance of survival.

Whether a 21-week premature infant can survive depends on the specific condition of the infant and the treatment and care provided after birth.

Premature infants are generally defined as babies born before 40 weeks of gestation. By about 28 weeks, most of the fetus's organs have typically developed sufficiently for survival outside the womb. Infants born at 28 weeks usually have a chance of survival, but those born at 21 weeks often face underdeveloped heart and lung functions, resulting in a significantly lower survival rate. However, with prompt medical intervention, good neonatal immune resistance, and high-quality medical care, survival is still possible. Conversely, if an infant is born at 21 weeks and does not receive timely treatment or if the available medical technology is inadequate, survival is unlikely.

After conception, women are advised to undergo regular prenatal checkups. If signs of preterm labor occur, it is important to rest in bed as much as possible, preferably in a lateral position, to increase uteroplacental blood flow and improve fetal oxygen supply, thereby minimizing the risk of premature delivery.
