What Does a NICU Nurse Do? A Day in the Life
When a newborn needs intensive medical care, every second matters. Behind every monitor, breathing tube, and incubator is a nurse constantly assessing, documenting, and responding to changes that can happen in an instant.
That's the reality of working in the Neonatal Intensive Care Unit (NICU). Most people picture nursing as bedside care alone. The role also demands constant clinical decision-making, teamwork, and documentation to keep the smallest patients safe.
Emma, a Registered Nurse (RN) in the NICU at Etobicoke General Hospital, shared what a day in the life of a NICU nurse really looks like, and why nursing is often very different from what people expect.
- NICU nurses care for newborns who need specialized medical treatment right after birth, including respiratory support and intensive monitoring.
- Every shift includes patient assessments, multidisciplinary rounds, diagnostic testing, feedings, and detailed documentation.
- Charting takes up about 60% of a NICU nurse's shift, leaving less time for bedside care and family support.
- Specialized technology, including isolettes and electronic documentation systems, plays a critical role in caring for critically ill newborns.
- Becoming a NICU nurse means becoming a registered nurse first, then completing additional neonatal training and clinical experience.
What Does a NICU Nurse Do?
A NICU nurse specializes in caring for premature and critically ill newborns who need medical attention right after delivery. These infants often need continuous monitoring, specialized equipment, and complex treatment during their earliest days or weeks of life.
"I care for newborn babies who need extra medical interventions right after delivery. Sometimes they're in respiratory distress and need CPAP to help regulate their breathing."
Unlike many other nursing specialties, NICU nurses care for patients who can't tell them what's wrong. Every change in breathing, heart rate, feeding, or behavior has to be carefully observed and interpreted. That makes frequent assessments and close teamwork essential.
What Does a Typical NICU Shift Look Like?
Every day looks a little different, but most shifts follow a structured routine built to keep each baby closely monitored.
- The shift starts with a handoff report from the outgoing nursing team.
- Nurses review patient charts and complete the first round of assessments.
- Multidisciplinary rounds follow, with physicians, pharmacists, and nurse practitioners reviewing each baby's progress and updating treatment plans.
- Assessments continue every 2 to 4 hours, depending on the baby's condition.
- Nurses coordinate blood work, imaging, feedings, medications, and new physician orders throughout the day.
- The shift ends with another detailed handoff to the incoming team, to keep care continuous.
"Every baby is different. Assessment frequency depends entirely on their condition."
The Part of the Job Most People Never See
Many people assume most of a nurse's shift happens at the bedside. In reality, documentation is one of the biggest responsibilities, especially in critical care.
| Activity | Share of Shift |
|---|---|
| Charting | ~60% |
| Direct patient care | ~30% |
| Everything else | ~10% |
Based on Emma's own account of a typical NICU shift.
In the NICU, documentation isn't just administrative work. NICU charting means every assessment, medication, feeding, intervention, and change in condition has to be recorded accurately to support safe care and communication between providers.
"Unlike adults, these babies have eighteen years to take legal action against the medical team, so our documentation has to be extremely thorough."
This isn't unique to one hospital or one nurse. Research on nursing documentation consistently shows charting takes up a significant share of working hours, time that would otherwise go to direct patient care. We've covered the broader data behind this in Documentation Burden: The Hidden Driver of Clinician Burnout, including a 2025 study of 80,000+ nurses finding 79% lose time to unproductive charting specifically.
If documentation took less time, Emma already knows how she'd spend those extra hours:
"I'd give more attention to families, be more available to help my colleagues, and actually get to leave my shift on time."
The Technology That Keeps the NICU Running
The NICU relies on specialized equipment most people never notice.
Isolettes
An isolette is an enclosed incubator built to create a stable environment for premature and critically ill newborns.
"Our isolettes regulate temperature, whether that's central or ambient air temperature, along with humidity and the baby's weight."
Electronic Documentation
Electronic records let nurses share information with physicians and the rest of the care team almost instantly. But the technology isn't perfect.
"The documentation system goes down randomly more often than people realize. When that happens, everything has to be charted by hand and transferred over once the system is back up."
Electronic health records have improved communication overall, but unexpected downtime can quickly add hours of extra work to an already demanding shift.
How Do You Become a NICU Nurse?
Working in a NICU starts with becoming a registered nurse. Here's how to become a NICU nurse, step by step:
- Complete a 4-year Bachelor of Science in Nursing (BScN)
- Pass the National Council Licensure Examination (NCLEX-RN)
- Register with your provincial nursing regulator (in Ontario, the College of Nurses of Ontario)
- Gain clinical experience, often in other specialties first
- Complete additional orientation and specialized neonatal training
Because NICU patients need highly specialized care, continuing education stays part of the job throughout a nurse's career.

For Emma, the most rewarding part of the job isn't just caring for newborns. It's supporting families through one of the hardest experiences of their lives.
"NICU nursing is a career for those who want to make a difference from the very beginning of life. By caring for critically ill and premature newborns while supporting their families, you'll play an essential role during some of their most challenging moments, where compassion and clinical expertise come together to create lasting impact."
It's a role built on clinical expertise, teamwork, and compassion, much of which happens quietly behind the scenes. Families remember the conversations and reassurance they received. Every one of those moments is backed by countless assessments, careful documentation, and constant vigilance that often goes unseen.

FAQs
What does a NICU nurse do?
NICU nurses care for premature and critically ill newborns who need specialized medical treatment after birth. They perform frequent assessments, administer medications, coordinate diagnostic tests, support respiratory care, monitor feeding, and work closely with physicians and other healthcare professionals.
How much of a NICU nurse's shift is spent charting?
According to Emma, an RN in the NICU at Etobicoke General Hospital, approximately 60% of a typical shift is spent completing documentation. While the exact amount varies by patient needs, charting is a major responsibility because it supports patient safety, communication between healthcare providers, and legal documentation.
What equipment do NICU nurses use?
NICU nurses rely on specialized equipment including isolettes, which regulate a newborn's temperature, humidity, and weight. They also use electronic documentation systems, patient monitors, infusion pumps, and respiratory support equipment such as CPAP.
How do you become a NICU nurse?
Most NICU nurses begin by earning a Bachelor of Science in Nursing, passing the NCLEX-RN licensing exam, and becoming registered with their provincial nursing regulator. Additional neonatal training and clinical experience are typically required before working independently in a NICU.
What is the biggest misconception about NICU nursing?
Many people believe nurses spend most of their shift providing direct bedside care. While patient care is central to the profession, NICU nurses also spend a significant amount of time documenting care, coordinating with the healthcare team, and managing complex clinical information to ensure every newborn receives safe, continuous treatment.
