Narrative:

We were cruising along at FL360 when we got a left bleed duct warning message. As we were running through the QRH we noticed that the cabin altitude was increasing. We got the cabin attendant altitude hi caution message and we initiated an emergency descent to 10;000 feet. As we were descending; the cabin attendant altitude hi warning message appeared which deployed the passenger oxygen masks. We continued our checklists and declared an emergency with ATC. We leveled off at 10;000 feet and contacted dispatch to let them know the situation and our intentions to continue on to destination at 10;000 feet. We had sufficient fuel to make the rest of the trip at that altitude. We were not in any icing conditions as the checklists required us to avoid. The skies ahead where clear. All thunderstorm activity was in our rear after the descent was completed. After the plane was secure; we tested the flight attendants and let them know that we were continuing; no passenger evacuation was required; and the time to our arrival. The cabin was getting a bit warm due to the packs being turned off per the QRH so our main concern was to get the plane on the ground and get the passengers off which we did in normal fashion at the gate. Dispatch and maintenance control were called upon arrival and the necessary log book entries were made.
