Pediatric intensive care unit

Overview
A pediatric intensive care unit, usually abbreviated to PICUis an area within a hospital specializing in the care of critically ill infants, children, and teenagers.

A PICU is typically directed by one or more pediatric intensivists or PICU consultants and staffed by doctors and nurses who are specially trained and experienced in pediatric intensive care. The unit may also have nurse practitioners, respiratory therapists, physician assistants, physiotherapists, social workers and clerks on staff although this varies widely depending on geographic location.

The ratio of professionals to patients is generally higher than in other areas of the hospital, reflecting the acuity of PICU patients and the risk of life-threatening complications. Complex technology and equipment is often in use, particularly mechanical ventilators and patient monitoring systems. Consequently, PICUs have a larger operating budget than many other departments within the hospital.

History
Goran Haglund established the first pediatric intensive care unit, which he called a "pediatric emergency ward", in 1955.

Infants were first kept intubated for long periods in the early 1960s. Breathing tubes made out of polyvinyl chloride (PVC) allowed clinicians to avoid performing tracheostomy (surgically inserting a tube into the windpipe) in more children who required prolonged mechanical ventilation.
