Nursing is a profession that requires competence on many levels: mental, physical, emotional, and interpersonal. Thus it seems a good nurse must be a well-rounded, exceptional person.

If this seems like a tall order to fill, it gets even taller for the ICU nurse, who must excel in each competency because of the nature of critical care work. Critical care patients suffer from life-threatening conditions, so their nurses must be knowledgeable, strong, quick, considerate, and wise, at the least.

But nurses aren’t just born that way. They gain these excellent qualities through education, training, hard work, and experience. If your goal is to become an ICU nurse, it’s not as unattainable as it might sound.

Let us guide you into a deeper understanding of the ICU nursing profession — what it takes and how to get there — so that you can begin the journey toward a career that will save lives and help you maximize your potential.

What Does an ICU Nurse Do?

All ICU nurses are responsible for the following:

An ICU nurse’s place of work depends on the specific certification earned. You can be certified to work with cardiac patients, trauma patients, and surgical patients, or in the NICU or PICU.

History of Critical Care Nursing

The development of critical care nursing and the first ICUs happened gradually, beginning in the 1850s when Florence Nightingale demanded that sicker patients be placed in beds closer to the nurse’s station for closer observation.

In 1923 Dr. Walter Dandy opened a three-bed unit at Johns Hopkins Hospital for the sickest post-operative neurosurgical patients, cared for by a team of specially trained nurses.

In 1930 Dr. Martin Kirschner designed and built an ICU for post-operative patients at the University of Tubingen in Germany.

Following the examples set by Walter and Dandy, most hospitals had built recovery units near their operating rooms by 1960. Throughout the next several decades more ICUs were added to serve critically ill patients for other reasons. The first multidisciplinary ICU was in the Baltimore City Hospital in 1958.

Initially, patients in the ICU were attended by different physicians, until it became clear that a specialized team of doctors and nurses could provide more effective patient care.

Advances in technology have allowed less invasive monitoring and assessment of ICU patients, and the relatively new focus on evidence-based practice has led to a reconsideration of protocols for intervention.

Critical care nursing has always involved working closely with doctors and other healthcare providers to provide advanced care for critically ill patients. It also involves learning about the patients’ needs and wishes so that they fully understand the care offered/provided to them. 

10 Responsibilities of an ICU Nurse

So what does an ICU nurse do? Specific responsibilities will depend on the type of critical care nursing:

Each type has its specific set of challenges, but all ICU nurses share certain responsibilities. 

#1: Assess and Treat Patients

The nurse commonly sees the patient before the doctor does, so it is the nurse’s responsibility to assess the patient and initiate care. Assessment includes: 

Treatment might include:

#2: Order and Perform Diagnostic Tests

An ICU nurse will likely need to send orders for diagnostic tests to determine the location and extent of an injury or illness. The nurse must decide which of the following tests are clinically necessary:

As you would expect, the ability to make these decisions requires strong, ongoing education

#3: Manage Wounds

The ICU nurse is responsible for management of wounds, such as:

Besides caring for the wound itself, the nurse must maintain clean bedding and keep a germ-free environment conducive to healing.

#4: Act as a Patient Advocate

Patients, especially those in critical condition, need help making informed decisions about their health. They need nurses who can translate medical jargon to them and their families in a way that makes sense. A nurse must be empathetic and have excellent interpersonal skills to do this effectively.

Besides explaining the medical side to patients and their families, the nurse should be the patient’s advocate to the doctors and other caregivers. This requires getting to know the patient’s wishes and beliefs about the care he/she is receiving or might receive.

#5: Monitor Medical Equipment

An ICU nurse must ensure that medical equipment is working properly and is in good condition. If a malfunction is identified, the nurse must arrange for repair or replacements. Proper maintenance of the medical equipment requires cleaning and storing it correctly.

Medical equipment found in the ICU includes:

Although most equipment in the ICU is standardized, older devices may need to be used at times. This means paying close attention to the variations between devices to avoid errors in operation. 

All equipment must be checked daily to ensure patient safety.

#8: Provide Post-Operative Care

#9: Document and Report

Documentation is on a level with treatment in terms of importance. An ICU nurse must record precise, detailed reports that include:

The nurse will report all these in consultation with the healthcare team and work with the team to plan interventions to achieve desired outcomes. These interventions must be recorded, along with their effect on the patient’s condition.

#10: Coordinate Discharge Plans

An ICU nurse helps to plan discharge and coordinate referrals to ensure that the patient receives continuity of care. All must be carefully documented.

The nurse makes sure that the patient understands discharge instructions.
