Critical care can be provided wherever lives are threatened - at the scene of an accident, in an ambulance, in an emergency room at a hospital, or in the operating room. Various terms such as Critical Care Unit (CCU), Intensive Therapy Unit (ITU), and Coronary Care Unit (CCU) can be used to describe these services at the hospital. Common examples of serious illness include heart disease, poisoning, pneumonia, surgical complications, premature birth, and stroke. Serious care includes trauma care - care for the seriously injured - whether due to a car accident, shooting or stab wounds, falls, burns, or industrial accident.
