Make sure your mask works before you go.
Put your mask on at the first sign of pressurization trouble.
Get down fast...but personally I'd try to coordinate with ATC first unless the cabin was in the 30's. Declaring an emergency will keep you from get violated, but may not keep you from hitting an aircraft below you.
Hope I'm not on your plane. Handle the slightest indication with seriousness and expedite down!
Turn off an airway if you're on one . Plus the other obvious emergency descent stuff. Set 10-15000' in the altitude select. Autopilot on. And you'll wake up at your preselected altitude if your O2 is broken. If time allows, select TCAS to 'below' so you can see traffic. Squawk 7700 and somewhere in there just state "callsign and emergency" after you've flown the plane and navigated.
Just did this in the sim yesterday. Took 4 minutes to get from FL410 to 10000'. And with spoilers deployed and thrust idle, it took 2m15s from the point altitude was captured till we received stick shaker. We had gear warning, stick shaker, and I think something else to wake us up. Then even when it stalled the autopilot had a trimmed airframe and because it was trimmed it had a gentle porpoise and had a 1300fpm descent.
But take these scenarios seriously IMO
