CO2: The rebreather incident

Martin Burnard · November 28th, 2007, 02:28 PM

An excellent film which highlights apsects for OC as well.

The big thing for me was the delay in addressing the diver that obviously had a problem. Sitting in the chair it's obvious, underwater not so.

I guess it brings us back to

"If in doubt, bailout!"

Oh so true! I thought a 3ltr was for suit inflation.

An excellent video.

CO2 is really debilitating, and simulating it by diving in a pool without a scrubber is no where near as bad as the real thing. Thats why your bailout HAS to be connected to your mouthpiece and available with a flick of your wrist. In my view, this switch to OC needs to be practiced on every dive.

This the second time I've heard of someone not getting gas from a back up reg, despite the fact they were working fine.

Hi gang,

Have seen the video a couple of times, and it seems Kevin (the poisoned diver) is breathing in OC on the DSV. If true, can think on suffocation but not during ascent (ppCO2 is reducing and gas on dead parts of lungs are expanding and removing).

May I be wrong or may it has a non real video, but also have seen a stage (guess a steel 7-8 lt).

The only time I have seen somebody on CO2 hit, his face was totally blue; but this is not a solid argument.

Cheers,

I overbreathed a RB once in strong current at 25m and had problems with CO2 - I didn't have a bailout mouth peice and it was the hardest thing that I have done switching to my necklaced backup. If it was more severe I wouldn't have been able to hold my breath for the 1 sec

I went out and ordered a bailout mouth peice the next day and I wouldn't dive
any RB at any depth without one now.
