Intensive care units cater 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 and nurses who specialize in caring for critically ill patients. ICUs are also distinguished from general hospital wards by a higher staff-to-patient ratio and to 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, hypertension, metastases and other life-threatening conditions.
These are found in hospitals certified in treating traumatic injuries/illnesses requiring a dedicated Trauma Emergency team equipped with the expertise to deal with serious complications. A traumatic specialist team includes surgeons, nurses, respiratory therapists, and radiological staff.
