Is the pediatric intensive care doctor on call 24 hours a day?

Pediatric: Depending on the shift, yes. If not , there is always backup coverage.

Most take shifts: A physician in any role develops whatever method of coverage to get the job done. In a small program, an intensivist might share duties with a pulmonary specialist and or hospitalist, each doing whatever they can to share responsibilities.As the program grows, additional intensivists would make up a specialty group and each would take turns doing after hour work or shifts.
