I made 4 dives between Sunday night and Tuesday morning in the Puget Sound, with max depths of 105', 103' 75' and 94' (on the last dive, we did about 30 mins at 15' at the end of the dive). I did a 3 hour SI before driving over the 3000' pass - as usual - and was thinking that some 100% O2 might be nice.
Wouldn't breathing straight O2 before flying or driving to altitude allow you to off gas faster and shorten the necessary surface interval ? Or, even with the required SI, decrease the risk of DCS? What about sucking down a tank of EAN32 on the surface? Waste of time?
