Hi Ralf,

I'm just an OC diver, so I can't comment on all the possible failure points
mentionned in an earlier email.  In fact, I don't know more than just basics
about rebreathers.  Over the past few years, I have noticed what seems to me to
be an irregularily high number of incidents with the inspiration.  If this
isn't due to the failure points as you suggest, what would be the cause? 
Inadequate training?  Natural causes?  Heart attacks?

Thanks for the info,
ss
