Add O2 to HDM Z1 Auto

Add O2 to HDM Z1 Auto
How, EXACTLY, should I add prescribed O2 to my HDM Z1 Auto output air?  And, will supplemental O2 add significantly to the pressure that is delivered to me?  My APAP settings are low:  4-6 cmH2O.  That is equal to 0.057-0.085psi.  I need this low pressure for proper therapy.  I am wondering if supplemental O2 will increase this pressure out of my range of tolerance.  My doctor prescribed 2 liters per minute of O2.  I have read that this results in pressures on the order of several psi - way higher than my therapy range.  If I install a one-way valve as instructed in such supplemental O2 setups, that will deliver all of the O2 pressure to me.  What will happen?

It depends,  
Some masks have an attachment for an O2 hose.  
I searched amazon for "cpap o2 adapter" and found them for a 22 mm hose.
