PP02 of .3 for 3 -5 minutes at 15'constitiutes any type of meaningful decompression tool

Most of these types dive air and wetsuits which leads me to postulate that the 'deco' benefit is supposedly present on the latter half of the thermal curve where warmth is severely depreciated. From DAN we know that DAN studies show cold tissue does not offgas as effectively as warmer tissue. So if you plotted out the curve of the deco stress (limiting it to the cold variable) and the theoretical advantages of five additional minitues on air they would cancel out if not show that by allowing for an additional five minutes of 'cold'deco conditions the individual would show an increased risk of bubbling from the 15 to 0 ft range due to decrease solubility of the tissue interface.


1) Dive the most appropriate mix + deco gas

2) More deco isn't always better it depends on where its at and what its on

3) If you are in a wetsuit pay even more attention to the above and ask santa clause for a drysuit.
