A 13 year-old boy with a history of allergic rhinitis is sent in to the emergency department by his family doctor. Three days previously he was exposed to smoke from a bushfire and has been having difficult breathing since. He has been having sudden exacerbations where his chest and throat feels tight and he feels as though he can’t get any air in. There has been no improvement despite treatment with prednisolone and ventolin over the past 2 days.
Can you diagnose and manage this case?
