I don't know the answer to this but would find this doubtful unless they are staffed by physicians. Nurses cannot dispense medications without a physician order. It wouldn't be responsible of a provider to dispense medication without a thorough examination a health history.[/QUOTE]
I think you are a bit confused by the post perhaps. No one would dispense medicine, people that use neb machines have small, sealed, one time use vials that are emptied into the conected hose/breathing apparatus.
Our (DS & I) asthma meds come 100 vials in a box and are very transportable, our nebulizer is not. If I were to put it into a backpack, basically it and our tubing, would be all the backpack could carry. I know there are smaller ones, the one we have is all that our insurance would provide.
All that a provided nebulizer in a First Aid station would do is A. Simply be the way medicine is delivered to that person and B Keep the person using it from having to provide their own/carry it at the parks! The person needing to use it would always have their own meds!
