ER Nurse vs ICU Nurse Differences

Both emergency room (ER) and intensive care unit (ICU) nurses play critical roles in healthcare settings. Each type of nurse works with patients in serious, life-threatening conditions. But make no mistake - their roles are vastly different and distinct.

Not only do ER nurses and ICU nurses have separate responsibilities, but they experience distinct work paces and environments and appeal to different personalities. Read on to learn more about the differences between ER and ICU nurses to find out which nursing specialty may suit you best!

What is an ER Nurse?

Emergency room nurses are licensed registered nurses who treat patients coming through hospital emergency departments. ER nurse patients come from all ages and backgrounds and suffer from various conditions. Consequently, ER nurses must prepare to treat a wide range of ailments, including trauma, injury, and acute-onset conditions.

What Does an ER Nurse Do?

From heart attacks to strokes, gunshot wounds, motor vehicle accidents, or fractured bones, ER nurses see it all.

ER nurses learn to quickly triage patients based on immediate observation and acute assessment skills, then treat symptoms in order of life-threatening priority.

They may immediately start CPR to reverse cardiopulmonary arrest, start slamming blood products for a hemorrhaging patient, or work to quickly discover underlying medical conditions that are less apparent. 

Specific ER nurse duties include the following:

  • Administering blood products, medications, and vaccinations 
  • Assisting in the care of traumas, cardiac arrests, strokes, sexual assaults, and conscious sedation
  • Cleaning and dressing wounds
  • Conducting cardiopulmonary resuscitation, rescue breathing, or bag-valve-mask ventilation
  • Discharging medically stable patients
  • Educating patients, families, and caregivers about their disease and treatment plan
  • Performing tracheotomies and intubations
  • Placing Intravenous lines
  • Responding to emergency situations throughout the hospital
  • Setting broken bones
  • Stabilizing trauma patients
  • Treating critical injuries, allergic reactions, and trauma
  • Triaging patients upon arrival to the emergency room

What is an Emergency Room Nurse Called?

Emergency room nurses are called a number of different names, including ER nurses, trauma nurses, and critical care nurses. 

What Makes a Good Emergency Nurse?

Most of the patients they see are experiencing emergency, life-threatening situations, so ER nurses have to be quick to recognize those acute problems and be able to resolve or stabilize them immediately upon arrival. The job is fast-paced, full of adrenaline rushes, and completely unpredictable from shift to shift, so you need to be able to think fast and react well under pressure!

What is an ICU Nurse?

On the other end of the spectrum, Intensive Care Unit (ICU) nurses treat patients who require the highest acuity of care in a very structured and controlled setting, the Intensive Care Unit.

In order to treat the most critical patients in the most thorough manner, critical care nurses use their specialized skills and extensive knowledge of disease pathology to provide interventions that sustain life.

Without ICU nurses, healthcare systems would be unable to accept trauma patients, end-of-life patients, and others who require highly specialized care. These nurses are specially trained and often cannot be replaced unless an individual has similar training and credentials.

What Does an ICU Nurse Do?

They care for the most fragile of patients who hang on to life by a thread. Most patients in the ICU are intubated, ventilated, and on life-sustaining medication drips at the very least.

Nurses need to be able to preemptively recognize signs of decompensation and act swiftly on them. They are advocates for their patients and work closely with the intensive care team to treat their patients. The environment is structured, high acuity, and multifaceted. 

More specifically, ICU nurses perform a variety of tasks and have numerous job responsibilities. These will vary depending on the healthcare system, but generally, ICU nurses perform the following specific duties:

  • Collaborate with healthcare professionals to provide holistic care to patients.
  • Educate patients and their families on diagnosis, medications, and other information
  • Cleaning and bandaging patient wounds
  • Tracking life support equipment
  • Immediately respond to changes in the patient’s condition.
  • Evaluating vital signs such
  • Administering medications
  • Acting as a patient’s advocate
  • Provide comfort and prevent suffering
  • Infusing blood products and monitoring patients for reaction
  • Caring for the patient’s body immediately after death
  • Identifying patient’s needs according to their age and level of consciousness and creating a care plan to meet them
  • Complete paperwork prior to transferring or discharging a patient
  • Respond to medical emergencies in the unit
  • Supporting a compassionate and therapeutic environment for critically ill patients

What Makes a Good ICU Nurse?

ICU nurses need to be able to work quickly, efficiently, independently, and meticulously. Furthermore, they need to be efficient, patient, and dedicated. 

Differences Between ICU Nurses and ER Nurses

ICU and ER nursing appeals to vastly different personalities and work-style preferences. So, let’s poke fun at some nurse personality differences:

1. Work Style

ER nurses thrive in chaos, while ICU nurses detest chaos. When it comes to the work environment, the two specialties can seem like opposite worlds.

ER Nurses have personalities that work best amid a storm of disorganization. It’s very hard to stress out an ER nurse. Because of the chaotic flow, ER nurses rely massively on teamwork and intuition. Ratios can be tough to manage, depending on who walks in the door, and these nurses run around like lives depend on it…and they do.

ICU Nurses, on the other hand, typically operate like well-oiled machines and wouldn’t have it any other way. ICU nurses appreciate shifts that are structured and organized and allow them to perform their work without hiccups.

2. Organization (or Lack Thereof)

I have never met an ICU Nurse who wasn’t meticulously organized in the best way possible. These nurses know their stuff. Checklists of exactly which medications are due and highlighted grids of which are compatible together, which drips to titrate and when exact intake and output of fluids to the milliliters of blood taken for lab draws, etc. It’s hard to catch an ICU nurse off-guard with a question about their patients’ care.

ER Nurses operate entirely differently, and for good reason. They don’t have the time or luxury to be detail-oriented. They only have the time to assess, react, and move on. So if you want to look at an ER nurse’s paper “brain,” don’t be surprised if they don’t carry one. Everything they need to know is up top.

3. Goals of care

In an ER, you never know who walks through that door next. ER nursing is the very big picture. You assess, identify the major problem, treat the major problem, and get the patient back out the door onto another appropriate floor because there are many others waiting for that bed. Prioritize, stabilize, and move out. You only have time for reactivity and responsiveness.

In the ICU, you can instead proactively think and act. ICU nurses have to look at everybody’s system as interconnected and treat it as such. Something that affects your neurological functioning affects your GI system, affects your liver, your kidneys, etc.

ICU nurses are planning for long-term goals for patients and often watch patients progress from critical illness to health again. The goal is not in and out - it’s long-term wellness. ICU nurses are very involved with patients and families, building rapport and providing education. ER nurses often don’t have the time for much interaction with patients and families beyond life-saving measures. 

4. Personality types

ER nurses are adaptable, calm, and collected during emergencies, quick-acting, big-picture thinkers, adrenaline seekers, love organized chaos, and their report is something like “the patient is alive.”

ICU nurses are meticulous, organized planners who love a detailed level of care, and they can simultaneously orchestrate 10 pumps, 6 drips, 4 beeps, and 1 crashing patient without blinking an eye. 

Although ICU and ER nurses alike are superheroes. They are incredibly smart and quick-thinking and save lives every single day. Hats off!

How to Decide if the ICU or ER is for You?

Deciding between the ICU and the ER can be difficult. The nursing skills needed both in the ICU and ER are similar. Nurses need to be highly focused and driven.

Ultimately, if you’re a high-energy person who’s able to think on your feet and remain calm in a crisis, ER nursing would be a better fit. The ICU lacks the urgency of the ER, but there is an immense amount of pressure because of the severity of the illnesses.

Education Requirements: ICU vs ER

The educational requirements and steps to become an ICU nurse or an ER nurse are the same

Step 1: Become a Registered Nurse

To become an ICU nurse, you must first become a registered nurse (RN). You can either graduate with a BSN or an ADN from an accredited nursing program.

Step 2: Pass the NCLEX-RN

Become a Registered Nurse by passing the NCLEX examination.

Step 2: Gain Experience

It is possible to become an ICU nurse or an ER nurse directly out of nursing school; however, don’t be surprised if some positions require prior bedside nursing experience. This might include at least two to three years of med-surg nursing

Furthermore, an ER may expect their nurses to have an additional two years of bedside ICU experience. If that is the case - it may take 4 to 5 years before landing a job in an ER. 

Step 3: Obtain Certification

ICU and ER nurses can earn advanced certification in their respective fields after earning the required amount of experience. While certification may not be required, it is highly encouraged and can lead to salary increases as well as additional benefits. 

The most popular certification for ICU nurses is the Certification for Adult Critical Care Nurses (CCRN), awarded by the American Association of Critical-Care Nurses.

To be eligible to sit for the CCRN exam, nurses must meet the following criteria:

  • Practice as an RN or APRN for 1,750 hours in the direct care of acutely/critically ill pediatric patients during the previous two years, with 875 of those hours accrued in the most recent year preceding the application.


  • Practice as an RN or APRN for at least five years with a minimum of 2,000 hours in the direct care of acutely/critically ill pediatric patients, with 144 of those hours accrued in the most recent year preceding the application.

ICU and ER Nurse Similarities

While the ICU might be slightly slower than an ER at times, a lot of nurses would argue that they are both very intense and require expert critical thinking skills. Both settings can see specific patients who have a variety of different illnesses, and both care for patients with life-threatening diseases.
