Carexpress transports critically ill newborns from area hospitals to the Neonatal Intensive Care Unit at the NMMC Women's Hospital, as well as critically ill newborns and children from NMMC to Le Bonheur Children's Medical Center in Memphis and other specialty hospitals.

Stationed at the hospital's Emergency Response Center on South Green Street, Carexpress is available 24 hours daily and staffed by highly trained neonatal and pediatric transport teams. The unit is taller and longer than most emergency vehicles with enough floor space to accommodate two incubators. This capacity is most helpful when transporting twins.

Carexpress looks like a fun ride, but its mission is quite serious. The unit has its own self-contained power plant that allows it to have alternative power sources. The unit carries oxygen as well as compressed air, which is mixed with oxygen and administered by a respiratory therapist.

In addition to the driver, who must be a registered Emergency Medical Technician with Mississippi State EMS driver certification, as many as four others can ride comfortably in the unit while attending to their patient. Depending on the nature of the case, these may include registered nurses from the Neonatal Intensive Care Unit, respiratory therapists and paramedics.
