What Does ICU Stand For?

ICU stands for Intensive Care Unit, it’s the area in a hospital where the sickest patients with the most life-threatening conditions receive care. Depending on the size of the hospital, there may be different ICU departments to care for patients of different ages and medical conditions.

What Is the ICU?

This is a specialized department found in many small to large hospitals across the United States. Doctors, nurses, and ancillary health care personnel working here specialize in providing patients who have unstable medical conditions with life-saving care.

Depending on the facility, the ICU is sometimes called the critical care unit or CCU. You will probably see these acronyms used across hospital signage and in many of your textbooks if you begin nursing school.

History Note:
ICUs were first introduced to the medical world over 50 years ago.

Which Patients Are in the ICU?

Patients requiring life-saving treatments or a great deal of hands-on care are admitted to the ICU where the nurse-to-patient ratio is far lower than it is on medical-surgical floors.

Once the patient’s health stabilizes, he or she will be transferred to a different unit or, in some cases, will be discharged home. Patients here often fit into one of the following categories.

  • Require advanced respiratory support
  • Require advanced cardiac support
  • Require medical support for more than one body system
  • Require medical support for one body system and also have a chronic health condition

What Is the Purpose of the ICU?

The purpose of any ICU is to save lives. This is done by stabilizing vital signs, treating acute medical concerns, and providing constant monitoring.

Rather than treating long-term care concerns, ICU doctors stabilize acute issues before sending the patient to a different team of doctors.

What Are the Different Types of ICUs?

While the most familiar type of ICU is the adult critical care unit, you may see several other types of critical care units in larger hospitals. These could include the following types of ICUs:

  • Medical ICU (MICU)
  • Surgical ICU (SICU)
  • Neurological ICU
  • Trauma ICU
  • Burn ICU
  • Cardiac ICU or Cardiac Care Unit (CU)
  • Neonatal ICU (NICU)
  • Pediatric ICU (PICU)
  • Transplant ICU

In the ICU, patients receive cutting-edge care utilizing the latest technologies and treatments.

They are also monitored quite closely by highly trained nurses and are regularly visited by a multi-disciplinary team of ICU physicians and ancillary staff, which could include respiratory therapists, social workers, dietitians, occupational therapists and many others.

Doctors are always on call even during weekends and holidays so that they can address new patient health issues as they arise.

In addition, staff members use specialized equipment to provide a closer look at each patient’s health, including oxygen status, blood pressure and neurological status.
