    Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane

    Some of these factors are known and can be measured and quantified, others are known, suspected or hypothetical, but not measurable or quantifiable, and some may still be entirely unknown. Decompression stress has been cited as a driver of bubble growth and a risk factor for symptomatic decompression sickness in humans and diving animals. [39] [62]
