What, like the ones at petrol stations?
That would do the job I'm sure. http://www.gooutdoors.co.uk/blog/dangers-carbon-mo...

Helium is better, apparently, for ducking out.
Any inert gas would do it. Your breathing reflex is triggered by CO2. If you inhale any gas with little or no oxygen (but no CO2), you won't even know it and pass out.I dive with a closed circuit rebreather, and you have to be very alert to what you are breathing. The rebreather recycles your exhaled breath; the trouble with that is that gas contains elevated CO2 and depleted oxygen. The exhaled breath is passed through sofa lime which removes the CO2, and squirts in enough O2 to replace what you have metabolised. If the unit did not put in enough O2, and you were not aware, the O2 in the breathing loop would gradually deplete and you would be a goner. Because the CO2 has been removed, you wouldn't know it is happening.

It's triggered by your blood CO2, no? (Been a while since I did this.) CO just bonds with your haemoglobin blocking the O2.

Purchase a VW camper - turn on cooker, forgetting that the pop-top is down and that the vents are thus covered, and that the windows are fully closed - easy peasy.
I somehow managed to realise that not all was OK just before conking out. I'd imagine it to be a nice way to go if that is the intention but, left me feeling like total crap/sick - no energy and with pins and needles in the head.

The diver made a spectacular f
k-up when he packed the scrubber (the thing that removes the CO2). The result was the exhaled gas bypassed it, and CO2 in the breathing loop was allowed to build up. Even though there is enough O2 in the loop, his lungs are being told to work harder and harder. Imagine holding your breath for as long as you can - your diaphragm will be aching and spasming. Because he can't get rid of the CO2, that feeling is only going to get worse.Rebreather divers carry an open circuit bailout i.e. a normal scuba regulator. Air comes down a hose to your mouthpiece, and when you exhale, the gas bubbles up to the surface. On the video, you can see exactly how hard he is breathing when he bails out by the amount of bubbles. He's going to be chuffing like a train until he's exhaled all that CO2 out of his bloodstream.

Something is up with the cooker then, and probably the conversion tbh.I somehow managed to realise that not all was OK just before conking out. I'd imagine it to be a nice way to go if that is the intention but, left me feeling like total crap/sick - no energy and with pins and needles in the head.
Carbon Monoxide poisoning is slightly different to breathing in Carbon Dioxide as CO is more unstable than CO2. When CO is released it wants to be CO2 and will grab any spare oxygen molecules it can find. After breathing in carbon monoxide, it enters your bloodstream and latches onto the oxygen molecules which subsequently forms carboxyhaemoglobin.
When this happens, the blood is no longer able to carry oxygen, and this lack of oxygen causes the body’s cells and tissue to die. It's not simply a case of suffocation.
