Intensive care unit definition is - a unit in a hospital providing intensive care for critically ill or injured patients that is staffed by specially trained medical personnel and has equipment that allows for continuous monitoring and life support —abbreviation ICU—called also critical care unit.

It is often difficult to know for certain whether a particular patient needs to be nursed postoperatively in the intensive care unit (ICU), if one exists in your hospital. The person making the decision, whether surgeon or anaesthetist, has to balance the risk of the patient dying from an avoidable cause on the ordinary ward against the waste of expensive resources if a patient is admitted to ICU for no good reason.

An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine.

The intensive care unit (ICU) is an area that is frequently the scene of serious security events, from disturbances to homicides. The ICU has the potential to be a highly charged atmosphere at any given time.

The intensive care unit (ICU) is a specialized hospital unit dedicated to the care of patients requiring life-support and those at extremely high risk for organ failure and death. Approximately 5.7 million individuals are admitted to an ICU in the United States each year (Barrett, Smith, Elixhauser, Honigman, & Pines, 2011).
