what did Jill say on NOVA?

[OutlawCaver]

One out of ten is terrible survival odds

As a statistics teacher, given equal probability among the users, it would actually be for 1 fatality per 10 CCRs:
9 to 1 (9:1) odds of surviving and 1 to 9 (1:9) odds against surviving.

9 in 1 odds of surviving and 1 in 9 odds against surviving.

Not to quibble, but don't you mean 9 TO 1 odds and 1 TO 9 odds. 1 in 9 is a 11.1% chance....not 10%.

Actually I was thinking about that when I went to lunch and decided I would change it when I returned and also show it as a mathematical ratio.

On the NOVA special last Tuesday, I thought I understood Jill Heinerth as saying that one out of ten rebreathers built has killed its user. Did I misunderstand what was said? I don't know how many rebreathers have been built, but that seems like a lot of expired divers. Please correct me or help me to understand what she meant. thanks.

The wording seemed a little unclear, I understood her to be saying that one out of ten rebreather makes has had a diver die while using them.

Throwing any homebuilt/garage units out of the equation, that actually sounds very low to me. I would hazard to guess pretty much all the well known manufacturers have had someone die while diving their rebreather. Please note, I did not say die from using their rebreather, big difference.

Well, I think you all misheard what she said. To paraphrase I think she said:

"We have to come up with some sensationalistic boowah or everyone will notice that Wes is getting old and bagged out".

Brian then said, "Hey, I know a hole where some poor putzes body is aging poorly, so we can go and film that".

To which Wes replied "Sounds good, and I'll wear a really cool red dew rag".

At least that how I think it went.

I find the "1 in 10" a little hard to believe- but my unit is probably nicknamed "yellow box of death" for a reason.

I think rebreather fatalities are probably in line with cave diving fatalities in the 60's and 70's. Once training requirements, standards, and mandatory equipment rules were enforced, fatalities per # of cave dives dropped. They still happen, but not like the bad old days. (My buddy and I taught ourselves to cavedive in the mid-70's. It was hard to even find an instructor then)

Today, rebreather training standards are all over the place. There are good rebreathers you can buy in kit form- until very recently there were no instructors for those units.

Rebreathers are not intuitive. Unlike open circuit, you can be breathing just fine- and not know you are breathing too much/to little O2, or too much CO2.

Rebreathers don't kill divers. Lack of training and complacency kill rebreather divers.

Well Said.

Yeah that comment went over well in my house. Just as well as the one about it being the most dangerous sport there is. That made the wife real happy.

Why did you let her watch, I'm still trying to recover from my last tongue lashing!
