Removing Carpet Glue

You didn't mention how large your room was, but if it is fairly small you may get away without having to restretch the carpet. You will probably need new tack strip as it is difficult to remove the old without breaking it. Worse case would be that you may need to rent a knee kicker to stretch it back if the results without are disappointing. If the room is large, you may want to have a kicker ready to go. In either case, don't forget to have a 3 or 4 inch chisel or stiff putty knife to tuck the carper edge back down behind the tack strip. Good Luck.

I don't know how true it is but I've heard a few times that certain plants do a good job of removing VOCs from household air. You could try investigating this claim. Here's one page that mentions it.

My wife has trouble with a variety of VOCs. It might not be an option for you to store the carpet partially outstretched in your garage until most of the odour departs.
