Reply to: RE>>Data point George, What are your sources for this? Amy source that is in print? I am after some more detailed data. Thanks Steve ------------------------------ Date: 11/14/97 1:38 PM To: Hogan, Steve From: gmirvine@sa*.ne* Dry you can take a lot. Wet shows seizures above 1.4 working, and 1.6 not wroking ( from commercial diving ). The pulmonary problems are still there , however, and that is why they do the breaks in dry chambers. Wet, you need the breaks for both reasons.
