A few months ago we had cabin pressure loss and my wife got detached retina and temporary deafness. It is a real thing. People have had pierced eardrums.
Did she get the retina reattached?
Normally a climbing aircraft that failed to pressurize would trip the alarms and have the pilot descend. To depressurize at altitude points to a hatch or glass failing somewhere.
How many passengers lost consciousness on your flight?
Probably zero - because I have not heard about your incident before.
Pierced eardrums after cabin pressure lost?
Your ears are connected to your throat via the Eustachian Tube.
In theory, air pressure on each side of your eardrums should balance instantly if your nose is not clogged, or if your mouth is slightly open.
