Possibly the treatment's better, but...

Using standard scuba kit is fine as long as regs/cylinder are O2
cleaned/service. We intend using an 11 litre cylinder with dual regs
on our boat, this will mean that we would be able to supply two divers
on the surface for 50 minutes or one for 1.5 hours.(assumes 25L per
min)
The standard O2 kits tend too be to small in capacity. The oral nasal
masks are fine, but are more suitable for unconscious casualties, and
I would suggest not for in water use.

a consideration, but this would need to be offset against helicopter
arrival, etc
>3. In the UK, hypothermia, divers drifiting away in the currents.
IWR should not be considered unless adequate precautions are taken eg
floating deco system which divers can attach themselves to, and boat
can easily follow.
any thoughts

* Heres a interesting problem, ( to me anyway ).
*
* MOst dive boats in the UK, Private or otherwise carry a O2 kit for
emergency
* purposes.
*
* In the event of a missed stop or a suspected deco incident, we would put
* said person on O2 on the boat.
*
* However would we be better giving the person the O2 kit and accompanying
them
* to 6m and telling them breath it there, Knowing that the treatment may be
* 1.6 times better but only 1/1.6 times as long, if you follow my logic
* ( probably flawed).
