The information I have indicates that the US Navy uses PO2 = 0.7 ATA for 
thier fully closed circuit Mark 15/16 rebreathers.  NEDU reports indicate
that this can spike to 1.8 ATA for some descent profiles.  Has the US Navy
adopted a new limit of 1.3 for thier fully closed circuit rebreathers?
I believe that for the old Emerson Semiclosed Circuit constant mass flow
rebreathers they limited the exposure to PO2 = 1.6 ATA for the supply gas
( actual exposure would be less ).

Is there a publicly available Royal Navy Manual equivalent to the US Navy
Diving Manual Volume 2 which describes Royal Navy rebreather diving 
operations?
