Good luck. Hope your little guy makes it.
And I would still take him to a vet to get X-Rays and whatnot just to make sure he didn't break anything that could threaten his life.
Ventilation is the only thing I can think of.
If you have a fan turn it on and open a window, also try to dry all the wet areas with a towel right away.
I'm just wondering if there's any breeders from the Orange County area in the forum.
I want a good, healthy chameleon, and well, reptile stores only have overpriced pets, and let's not talk about chain stores like PetCo or PetSmart.
