This is one of THE best sites for information regarding severe allergic reaction, and anaphylaxis relates directly to asthma. There are many links to short video clips which are especially geared toward young adults and children and are just as good for adults with asthma or children dealing with it. Unfortunately, there is not as much info on asthma as there is for anaphylaxis on this link, but there are many other links to try. I highly recommend this site for anyone.
