From _The Space Shuttle Operator's Manual_ by  K.M.  Joels,  G.P.  Kennedy,
and D. Larkin, Ballantine Books, 1982, section 2.2, paragraph 2:

"An atmosphere like the earth's is  maintained  in  the  crew  compartment.
Atmospheric  pressure  is  14.7  psi  ...  the  same  as standard sea-level
conditions.  The atmosphere consists of 79% nitorgen and 21% oxygen,  again
very  close  to what you left on earth.  In an emergency, cabin pressure is
reduced to 8.0 psi ..."
