New born babies who need intensive medical care are often put in a special area of the hospital called the neonatal intensive care unit (NICU). The NICU has advanced technology and trained healthcare professionals to give special care for the babies. NICUs care areas for babies who are not as sick but do need specialized nursing care. Most babies admitted to the NICU are preterm (born before 37 weeks of pregnancy), have low birth weight (less than 5.5 pounds), or have a health condition that needs special care. The premature baby will be supported by a lot of different devices. Most of them are involved in helping them breathe, receive nutrients and stay warm. Its doctors are all neonatal specialists.
