(Name withheld), a physiologist and IANTD instructor, responded to me along the same lines that George Irvine has stated previously, i.e. if heavy exercise is contemplated shortly after a dive, then the diver should try to get as close to heliox as possible. Now what is your point Wendell Grogan, M.D., ANYTHING? Michael J.
