I am sorry but unsure how to start a new post. I just received a Volara nebulizing machine with instruction from the respiratory therapist. I used it for the first time this morning. There is still saline in the nebulizing port. Does anyone have this Volara and does it not use up all the saline during a treatment? My machine is also set on "medium" for now. The therapist said to start there and work up to the "high" setting. Maybe more solution will be gone on that setting? And do most use the high setting? I do feel it works better than my nebulizer I had that was 3 years old. Thanks for any help/suggestion.
