Having read a translation of the report, (which accuracy i can in no way check) the following grabs me. "> Both divers said they forgot to flush the RB80' Loop before ascenting till arrive at the first stop (change mix) at 66m. They also said they do not remember what happened during this part of the dive and that sometimes breathing became ¨heavy¨. Arriving at 40m , Luiz Toledo said he was having difficulties to coordinate movements of his bellow members. " Basically the only achilles heel of the RB80/DC55 design is the need to flush the loop continuesly when ascending. Not suprising breathing became "heavy" or that they do not remember that part of the dive when hypoxic. Would this have been the starting point of the chain of unfortunate events or I am completely out on the wrong limb here ? regards /e -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
