Subject: sudafed -o2 prob

        I know that this is the wrong address for cavers - maybe someone 
     could forward.  I read that someone said something about the Navy and 
     Sudafed on these lists.  I called a hyperbaric/medical doctor type 
     that I work with at NEDU and asked if the Navy truly has said anything 
     about Sudafed and O2 tox.  He is checking for me there and at NMRI.  
     I'll let you know.  I used Sudafed extensively in the upstream 
     Sullivan exploration - its a killer on the ears scootering from 0 to 
     140 to 80 to ... and I had some serious ear problems (still do). I 
     even took additional tablets during the dive, as these dives were in 
     excess of six hours.  I never had problems but this is shallow stuff.  
     I do believe we were using O2 at 30' back then though.  Since I've 
     heard about possible problems, I don't use it any more and I don't 
     start with O2 till 20'.  It will be interesting to see any real test 
     data.  NMRI has been involved with O2 tox testing, lately.
