CO2 hit on video........

CO2: The rebreather incident

[PlatypusMan]

That's one good video, with what appears to be good information.

Rebreather divers: is repacking still a practice that you see happening?

I liked it, I dont dive a rebreather and honestly dont have a passion to use one, not because of the risk I just dont want to pay out at least 5000 bucks. This video was very educational, I lived the animations that showed how the rebreather works

[RoadRacer1978]

Very informative. Glad everything woked out ok.

Lucky man!

I wonder how many rebreather deaths are due to this?

I am not a rebreather user. But I thought I saw in the film clip that there is a sensor in the "reconditioned" breathing gas. Why didn't the high level of CO2 trip some sort of audio/visual alarm? Why wasn't the diver alerted to some sort of problem so that he could start his ascent before he lost his ability to reason his way through the problem?

This is a very good training film and I'm sure it will be used as such. Thanks for sharing this as I learned a little something about rebreathers. I have never and likely will never have the opportunity to use it but it does interest me a great deal.

Thanks for sharing that! It's a great little video.

Exactly what I was wondering. Surely some of the divers on here with experience with these units will chime in shortly.

Thanks for sharing this video texdiveguy.

From Wikipedia (http://en.wikipedia.org/wiki/Rebreather#Failure_prevention)

Carbon dioxide gas sensors exist, but they are not sensitive enough to be used in a rebreather - the scrubber "break through" occurs quite suddenly and the diver shows symptoms before the sensor indicates a dangerous build-up of carbon dioxide. Even if a sensitive carbon dioxide sensor is developed, it may not be useful as the primary tool for monitoring scrubber life when underwater, because mixed gas rebreathers allow very long dives where long decompression stops may be needed: knowing that the rebreather will begin to deliver a poisonous breathing gas in five minutes may not be useful to a diver needing to carry out an hour or more of decompression stops.
