Sorry to hear that. Its academic now but I think what you were talking about when you said 'drs said too much 02 wasn't helping him breathe' is called hypoxic drive. You and I depend on raised c02 to stimulate us to breathe. For long term smokers where the c02 gets raised chronically, low 02 takes over as the drive ie hypoxic drive. If you then give too much 02 you take that drive away and they breathe less.
Sorry again
