Respected user, hi I evaluated your query thoroughly.
*Underlying inflammation irritating bronchi & alveoli are responsible for his
condition.
*He requires hospitalisation with detail work up in form of X-ray Chest,
Pulmonary function test ,
Allergy tests & intensive management in form of
Specialised nursing care, IV antibiotics , bronchodilators to take care of the
condition.
@Till then, let him rest in semireclining position ( supporting back for 30-40
degrees ) , maintain his hydration levels , BP .
Hope this clears your query.
Thanks for using Health Care Magic & keeping trust in our medical services.
Wishing him fast speedy recovery for the same.
Regards take care.
