Admittedly I'm not familiar with your practice. The details of your art are not clear to me from your post. Perhaps it can deal with asthma, perhaps not. But it is certainly not common practice, and you present it in such a way that a layperson may conclude that asthma as a medical condition can resolve with back slaps. My concern is that someone may attempt to use this technique when what they should really be doing is seeking qualified medical help.
