Is someone who suffers from asthma and needs to use a nebulizer to make it easier for them to breath (not pekuach nefesh) allowed to use it on Yom Kippur? (In a way of course that it'll be turned on for example by using a Shabbos Clock.) Is the inhaling of the mist/steam/whatever comes out considered to be like drinking or not?
(This is a theoretical shailo that I'm only looking for sources on or possible re'as to formulate a teshuva to this.)
