The event occurred on touchdown when the cabin depressurized and climbed rapidly.Inbound on the arrival; I briefed a visual to Runway 25L. As I started the arrival; ATC asked us to descend via. Then; the next controller changed/modified several speed and crossing restrictions. In addition; we received a last minute runway change. We were very busy during the arrival portion of the flight.I was focused on complying with and meeting the altitudes and speeds on the arrival. As a result; I was hyper-focused on meeting the crossing restrictions. Even though we ran the checklist; we missed the setting for the field elevation. In the future; regardless of how busy we are on an arrival; I need to remember to take a moment to back the other pilot up.
Distracted by ATC modifications to the constraints of a complex arrival and a late runway change the flight crew of a CRJ-700 failed to program and confirm the appropriate cabin altitude for the landing airport elevation and the cabin climbed rapidly to ambient upon touchdown.
