Hi Everyone,

In a private email message, it became clear that some people thought I was
saying that you can manage a diver who is convulsing underwater *while
they breathe from a scuba mouthpiece*.  This was not my intention.  An O2
convultion while breathing from a scuba mouthpiece is very difficult/imposs-
ible to manage.  Staying down while their convulsion subsides will almost
certainly result in them drowning.  When I said you should not change the
depth of a convulsing diver I was refering only to those who have a breathing
system that means they will not aspirate water.  With a scuba type system
you would have the choice between drowning them, or *possible* embolism. :(

My original post on this was to point out that the *comms* requirement of
an Edmonds table could be met with line signals, saving several thousand
dollars.  I was *not* saying you can do without a full face mask.  A FFM
*without* comms can be purchaced for around $150 AUD.  (eg Cressi Sub,
TechniSub or Poseidon FFM's)  A mask for comms is about $800 AUD plus comms
themselves, for thousands.  (you also need two masks, one for the attendent
and one for the diver)
Sorry for the confusion
Cheers Jason (Clan Cameron)
