My thoughts....
1) is he on statins? They were shown in UK to cause a lung disease called pulmonary fibrosis.
So the solution would be to stop them. (but at this late date? -- at least start the CoQ10).
2) if he does not eat fish or Omega-3's, then taking those may help with the lung tissue to rebuild it.
But it might be too late for him, unfortunately. But, he is lucky to have a friend like you.
