Critical care is the direct delivery of medical care, by a physician.
There is usually an ICU Consultant leading a team of doctors who normally examine patients on a daily basis to assess their progress and decide all aspects of treatment and care. Many have special experience, education and training in caring for critically ill and injured patients.
The critical care team consists of nurses, doctors, pharmacists, respiratory therapists, social workers, physical therapists, and occupational therapists. In general the ICU is more general and cares for patients with a variety of illnesses and the CCU is mainly for patients with cardiac (heart) disorders.
