Narrative:

When inspecting the logbook I saw the number 2 pack was on deferral. Our first flight of the day was a normal flight. The second leg; while at cruise; FL370; we received the ECAM air engine 1 bleed leak. First officer continued to fly while I performed ECAM actions. The left bleed valve had automatically closed and I noticed the cabin altitude climbing. We advised ATC and started an emergency descent to 10;000 feet. We then received the ECAM cabin attendant pr excess cabin attendant altitude and we complied with the ECAM actions while descending. Flight attendant a called the flight deck and I informed him of the problem and I would call him back shortly. Passenger oxygen was not needed as the cabin altitude did not reach 14;000 feet. At 10;000 feet and all ECAM actions complete the fault light extinguished on the left engine bleed; so we decided to turn the left engine bleed on in an effort to regain pressure. A leak was not detected and the aircraft pressurized. We were approximately 160 miles from destination so we elected to continue. I informed maintenance and dispatch of the situation and they concurred to continue. I called the cabin and briefed flight attendant a. The flight continued to [our destination] without further incident.I'm not sure. This would not have been an emergency if we didn't have the number 2 pack on deferral.
