Right Bleed Duct warning sign came on at 29;000 feet; I called for Appropriate QRH checklist and the pilot not flying started to read through the checks and while he was still reading the QRH we had warning sign for auto shut left bleed duct came up and the cabin pressurization started to decrease. We informed ATC that we needed to descend to 10;000 feet immediately and we were given a clearance to go down; and requested vector back to ZZZ. After completing appropriate QRH Procedure; we safely landed back at the ZZZ airport.
A CRJ-900 First Officer; climbing out of FL290; experiences a right bleed duct warning followed shortly by a left bleed duct warning and consequent loss of both packs. A descent to 10;000 feet is initiated and a return to the departure airport.
