Neonatal Intensive Care Unit (NICU)

Expert care for newborns who need extra support 

Banner Health cares for premature, small or seriously ill babies in our Neonatal Intensive Care Units. Our neonatologists and NICU specialists are dedicated to delivering advanced, compassionate care to give your baby the strongest start. 

What is the NICU? 

The Neonatal Intensive Care Unit (NICU) is a specialized area in the hospital for babies who need close monitoring or medical treatment after birth. Most babies do well and can stay in the regular newborn nursery. However, some babies need extra support because of: 

  • Premature birth 
  • Low birth weight 
  • Breathing or heart problems 
  • Infections, seizures or other medical concerns 
  • Birth defects 
  • Complications during labor and delivery 

Maternal factors such as age, health conditions or carrying multiples may also increase the chance of NICU care. 

Levels of NICU care 

Banner Health offers four levels of newborn care. Most babies stay in a Level I well baby nursery, which provides standard care to healthy, full-term newborns. 

Babies with mild health needs or those who are late preterm may receive care in a Level II special care nursery. Babies born before 32 weeks or with more serious medical issues receive care in a Level III NICU, where they can be closely monitored and given breathing support and other treatments. 

If a baby is born extremely early, has a very low birth weight or needs complex surgery, they may require the highest level of care in a Level IV NICU. These units provide advanced treatment with access to pediatric surgical and medical specialists. 

Conditions treated in Banner Health NICUs 

Babies may receive help with: 

  • Breathing support for underdeveloped lungs 
  • Feeding and nutrition, including breastfeeding support and donor milk
