I agree that we should fly the airplane first, but some airlines instruct their pilots to notify the passengers of an impending emergency descent. In my case, we have to instruct the passengers to "put on their masks and pay attention to the flight attendants because we had a sudden lost of pressure and will have to descent at a higher than normal rate of descent"!? I just think it is too much to say when you have a lot in mind.
Regards.
