What does an ICU nurse do?

ICU nurses play a key role in providing patient care under the supervision of doctors. They routinely perform head-to-toe physical examinations of patients, administer medication and provide wound care. ICU nurses interact with families to provide updates on their patients’ condition and seek medical decisions.

ICU nurses often have to react quickly to emergency situations and demonstrate a high degree of flexibility in life-or-death situations. They are sometimes called on to work overtime or to take irregular shifts.

Some critical care nurses work in special units for pediatrics or hospice care. Common ICU nurse careers can include:

  • Acute/Critical Care Nurse-Adult (CCRN-Adult). These nurses work in ICUs and cardiac care units to care for adults in critical condition.
  • Acute/Critical Care Nurse-Pediatric (CCRN-Pediatric). These nurses work specifically with children who need intensive care.
  • Acute/Critical Care Nurse-Neonatal (CCRN-Neonatal): These nurses specialize in caring for infants, often those who are born prematurely and with significant medical issues.
  • TeleICU Nurse: These nurses provide remote care via audiovisual communication for patients at home or in a care facility.
  • Transport/Flight Nurse: These nurses provide care to critically injured or ill patients during inter-facility transfers in an ambulance, as well as emergency transport in a helicopter or plane.
  • Head CCU Nurse: These nurses lead critical care departments such as ICUs, NICUs and trauma units. This is a management position that has less hands-on patient care and more supervisory and administrative duties.

ICU nurse skills and qualifications

To succeed as an ICU nurse, workers need a broad variety of skills. Qualified ICU nurses should have a large set of job-specific skills and qualifications, including:

  • Strong organizational abilities and good communication skills
  • High-level interpersonal skills and the ability to connect with patients’ families during stressful experiences
  • A valid nursing certificate or BSN degree from an accredited college or university
  • The appropriate license to work as a nurse in their state/county
  • Training in emergency response, disease control and other hospital-specific skills
  • Fluency in patients’ language(s)

ICU nurse experience requirements

Critical care nurses who work in ICUs typically have a lot of experience in nursing before they transfer into advanced patient care environments. Entry-level ICU nurses have usually worked for several years in nursing, in addition to the extensive education and certification requirements.

ICU nurse education and training requirements

While it’s possible to get a start in nursing with a vocational certificate from an accredited college or training institute, ICU nurses are generally expected to have a bachelor’s degree in nursing. After obtaining the basic nursing degree, critical care nurses must pass the National Council Licensure Examination (NCLEX-RN) test. To transfer into critical care, a qualified RN is expected to obtain a CCRN certification from the American Association of Critical-Care Nurses.

Certified CCRNs are generally qualified to look for entry-level work as ICU nurses, but there are further steps that can expand their career opportunities. Many ICU nurses go on to obtain a master’s degree in nursing (MSN). This degree, along with several years’ experience in ICU nursing, is a common prerequisite for advancement into administration and lead nurse positions.
