The PICU is the section of  Baby Hospital that provides sick children with the highest level of medical care. It differs from other parts of the hospital, like the general medical floors, in that the PICU allows intensive nursing care and continuous monitoring of things like heart rate, breathing, and blood pressure.

The PICU also allows medical staff to provide therapies that might not be available in other parts of the hospital. Some of these more intensive therapies include ventilators (breathing machines) and certain medicines that can be given only under close medical supervision.
