NICU Guide
Twin NICU Terms Explained
Plain-English explanations of common NICU words, acronyms, and equipment twin parents may hear.
Important Disclaimer
This guide is for educational purposes only. It does not replace medical advice. Always ask your baby’s NICU team to explain anything you do not understand.
The NICU can feel overwhelming at first. There are monitors beeping, nurses moving quickly, medical words flying around, and tiny babies connected to things you may have never seen before.
If your twins need NICU time, learning the language can help the experience feel a little less scary. You do not have to understand everything right away. One term at a time is enough.
As a registered nurse and twin mom, I know how much words matter. When you understand what the team is saying, it is easier to ask questions, follow updates, and feel like part of your babies’ care.
Quick Navigation
NICU Places & Equipment
NICU
NICU stands for Neonatal Intensive Care Unit. It is a special hospital unit for newborns who need extra monitoring, support, or medical care.
Isolette
An isolette is a clear enclosed bed that helps keep a baby warm and protected. It may look intimidating at first, but it is often used to help tiny babies conserve energy and stay stable.
Open Crib
An open crib is a regular hospital baby bed. Moving from an isolette to an open crib can be an exciting step because it often means your baby is better able to maintain body temperature.
Warmer
A warmer is an open bed with heat above it. It helps babies stay warm while allowing the care team easy access.
Breathing Terms
CPAP
CPAP stands for Continuous Positive Airway Pressure. It helps keep a baby’s lungs open while they breathe on their own.
Nasal Cannula
A nasal cannula is a small tube that sits under the nose and gives extra oxygen or airflow.
Ventilator
A ventilator is a machine that helps a baby breathe. Some babies need this temporarily while their lungs grow stronger.
Room Air
Room air means a baby is breathing regular air without extra oxygen.
Monitor Terms
Brady
Brady is short for bradycardia. It means the baby’s heart rate dropped lower than expected.
Desat
Desat is short for oxygen desaturation. It means the baby’s oxygen level dropped lower than the care team wants.
Apnea
Apnea means a pause in breathing. Premature babies can sometimes have apnea because their nervous systems are still developing.
Pulse Ox
Pulse ox is short for pulse oximeter. It measures how much oxygen is in the baby’s blood.
Feeding Terms
NG Tube
An NG tube is a small feeding tube that goes through the nose into the stomach. It can help babies get nutrition while they are still learning to eat by mouth.
PO Feeding
PO means feeding by mouth. This may include bottle feeding or breastfeeding.
Gavage Feeding
Gavage feeding means milk is given through a feeding tube.
Fortifier
Fortifier is added to breast milk or formula to give extra calories or nutrients when babies need help growing.
Care Team Terms
Rounds
Rounds are when the medical team reviews each baby’s progress and plan for the day. This is a good time to listen, ask questions, and write down updates.
Neonatologist
A neonatologist is a doctor who specializes in caring for premature or medically fragile newborns.
Respiratory Therapist
A respiratory therapist helps manage breathing support, oxygen, CPAP, ventilators, and other respiratory needs.
Lactation Consultant
A lactation consultant helps with breastfeeding, pumping, milk supply, latch, and feeding plans.
You Are Allowed to Ask Questions
NICU language can feel like another language at first. You are not supposed to know every term on day one.
Ask what a word means. Ask why something is being done. Ask what the next goal is. You are your babies’ parent, and you are an important part of their care team.
