Describe the intensive care unit (ICU).

What will be an ideal response?

Patients with life-threatening diseases or trauma frequently need specialized care. This can include intensive monitoring using specialized electronic monitoring equipment. In some cases, the patient's breathing must be supported through mechanical devices known as ventilators. In comatose patients, feeding tubes are used to maintain the proper dietary nutrition levels. ICUs maintain the equipment, systems, and staffing to support these patients. Some ICUs also care for cardiac patients, but usually this is accomplished in the CCU.
