I don't get it. Can't a person stay conscious for longer than 30
seconds without breathing? Most people can hold their breath for over
a minute.

If the drop in pressure is rapid, can a person hold in the air? Or
perhaps it is expelled because the pressure in the lungs is double the
cabin pressure?

If the pressure drop is rapid, they need to exhale, otherwise their lungs
will burst. Just like surfacing in scuba diving.

I don't believe there's ever been a case of pulmonary barotrauma (absent of
prior lung pathology) from decompression in commercial aviation. The
differential between 50,000' and 8,000' is less than that typically involved
in scuba incidents. May be possible though.
