RT here...Inhaled corticosteroids in general yes. We only nebulize via ultrasonic neb via our HFOV but on our population that has a lingering O2 demand I feel we have success with Flovent BID via spacer/mask. I was a longtime non-believer but over the last 10 or so years I've been convinced it helps us wean quicker. I've never seen ADR, its quick and easy.
