Newborns needing critical tertiary and quaternary care -- most often premature babies suffering from respiratory and circulatory problems -- can be admitted just minutes after birth. Our 54-bed NICU includes four multi-patient rooms, six single care rooms, four private rooms for "rooming in," and two four-bed suites. The unit also features a two-bed Extracorporeal Membrane Oxygenation (ECMO) unit. The life-saving ECMO unit is the only one of its kind in Orange County and CHOC also offers Orange County's only ECMO transport unit.
