It is a section of the hospital that provides sick children with the highest level of medical care. The unit differs from other sections of the hospital, like the general medical floors. A PICU comes with intensive nursing care and continuous monitoring of aspects like breathing, heart rate, and blood pressure of the child. The Paediatric Intensive Care Unit also allows the medical staff to provide medical therapies that might not be available in other sections of the hospital. Some of these intensive therapies include ventilators (breathing machines) and certain medicines that can be offered only under close supervision.
