 In reading the forward of the Navy Dive Manual Revision 3 vol 2 foreward it
states,"As you peruse this manual, you will notice that the old
Surface-Supplied Helium-Oxygen Partial Pressure Tables are missing.  These
tables have been replaced with the Minimum/Maximum Percent Oxygen Tables that
ensure the limiting factor of oxygen never exceeds 1.3 ata."  Doesn't say
why.  Is it because O2 during deco is used in such high pp?  It seemed
strange(only from the point of my ignorance) that the Navy would be so
conservative relative to NOAA.  I realize I'm mixing apples and oranges a bit
ie nitrox vs heliox but I haven't seen anything that would indicate ppO
issues should be different because of the other gases involved.  
Any light appreciated.
