When you do this you are using the CCR as a "fixed" volume fraction
semiclosed circuit rebreather ( instead of fully closed ).  See 
Bennet and Elliott 2nd edition for a good description of how this type of
rebreather functions.  The recently defunct ( and appearantly soon to be 
resurrected ) BMD rebreather worked on this principle.  The current Odysee 
works on a modified version of this.
