It may be a nebulizer. I really have no clue. All I know is that its a small compressor that is supposed to pump a fine mist through a tube and into a trach mask for me to breathe. Other than that its just a small air compressor to me... LOL

I dont really know if I need it or not but they brought me another one today that is quieter than the one they brought yesterday. I think Im gonna try and put it in my closet and run the hose to my bed and see if its still strong enough to push the mist to where I need it.

I will keep ya posted.
