As you are on highest doses of painkillers possible, still I would suggest for your case - preference of semi reclining position - intravenous or oral bronchodilators, corticosteroids - deep breathing exercises, meditations - positive thoughts - no smoking if doing Hope this clears your query. Welcome for further questions. Regards.
