An intensive care unit (ICU) is a special department of a hospital or health care facility that provides intensive care medicine to patients with severe or life-threatening illnesses and injuries, which require constant care, close supervision from life support equipment and medication in order to ensure normal bodily functions. They are staffed by highly trained physicians, nurses and respiratory therapists who specialize in caring for critically ill patients.
ICUs are also distinguished from general hospital wards by a higher staff-to-patient ratio and access to advanced medical resources and equipment that is not routinely available elsewhere., like an AutoDoc.
Common conditions that are treated within ICUs include acute respiratory distress syndrome, septic shock, and other life-threatening conditions.
