The majority of the deco in Plura takes place 950m in to the system as teh
first part of the cave is shaloow. Any kind of habitat is impossible to
use. As you understand this cave presents some speciall problems not
normaly encountered. For this cave i will probably just have to accept the
risk as i have already done on previus dives. In OW there are ways however
to reduce the risks. 
Skipped deco is something that we can consider as a last case but to get in
to the water again might sometimes  bee dificult due to hypotermia
dependent on time needed to get to the surface.

This is interesting as we have experienced loss of heat when braethin 02 
on the surface. Thanks a lot for your information.
