I happen to be away doing the following for the first time: I asked my pulmonologist if I could do this (did not inquire for how long) and he replied that he would rather that I use an aerobika but had no problem with my doing this while on vacation. I am finding it so incredibly freeing! I just use a disposable nebulizer ($2.99 per unit), bring my saline, and my small compressor and away I go!!! For example, if I am away for 5 days, I bring 5 disposable nebulizers (all in individual small bags -easy to pack), I simply throw the nebulizer out when done. I no longer bring bowls, worry about having a microwave, purchasing distilled water for cleaning and rinsing, etc,, etc. Hope this is helpful. Please check with your doctor to make sure that he/she has no problem with your doing so.
