What is the full form of ICU and CCU in Hospital?

Full Form of ICU→ Intensive Care Unit
Full Form of CCU → Critical Care Unit

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 healthcare facility that provides intensive treatment medicine.

Intensive care units cater to patients with severe and life-threatening illnesses and injuries, which require constant, close monitoring and support from specialist equipment and medications in order to ensure normal bodily functions. They are staffed by highly trained doctors and nurses who specialize in caring for critically ill patients. ICUs are also distinguished from normal hospital wards by a higher staff-to-patient ratio and access to advanced medical resources and equipment that is not routinely available elsewhere. Common conditions that are treated within ICUs include acute (or adult) respiratory distress syndrome (ARDS), trauma, multiple organ failure and sepsis.

Patients may be transferred directly to an intensive care unit from an emergency department if required, or from a ward, if they rapidly deteriorate, or immediately after surgery if the surgery is very invasive and the patient is at high risk of complications.
