alternative treatment never to late i hope

So my son Zakk has finiished his brutal radiation/chemo treatement--one year and two months of that, WOW!!!  Alternative treatment that i wanted was thrown out as  soon as the idea came out of my mouth, as it would interfere with the effect of the chemo, etc.

Okay so now that he survived that nuclear war on his body, I'm going to pursue this Oxygen therapy .  again, the team states it's a waste of time if he is getting 95-100 percent oxygen (reading from the finger)  Just because there is oxgen in our bloodstream doesnt mean it is reaching our organs as the chamber forces it through.  

I disagree, this is a completely different issue.  this chamber is supposed to be the answer to bringing the damaged organs back to good working order.  

does anyone have any input on this??
