In PA-LOD, what sequence best describes cabin altitude monitoring and rapid descent coordination?

When cabin pressure is lost, the top priority is to get oxygen to everyone and rapidly reduce cabin altitude by following the emergency descent procedure in the QRH. Donning oxygen masks for crew and instructing passengers to do the same is essential to prevent hypoxia as the aircraft descends. Then execute an emergency descent per the QRH to reach a safe altitude as quickly as possible, while at the same time coordinating with ATC to declare an emergency and obtain priority handling and necessary airspace clearance. This combination—oxygen on, rapid descent per the prescribed procedure, and ATC coordination—is the most effective and standard response for maintaining safety during a pressurization loss. Rationale for the others: attempting to maintain cabin altitude with an automatic pressurization adjustment isn’t feasible during a depressurization event; you must descend. Relying on automation alone without ATC coordination ignores essential airspace and traffic considerations. And while notifying passengers is important, the key actions are providing oxygen, following the emergency descent procedure, and coordinating with ATC rather than waiting to continue cruising.
