Hyperbaric Oxygen

If the only hope for the ending of the Russian invasion of Ukraine is dependent on the death of Vladimir Putin, then there is hope that Putin himself may be expediting this with his own stupidity.
This article appears to indicate that Putin is using a hyperbaric oxygen chamber to rejuvenate himself. Oh dear. As Paracelsus pointed out 500 years ago "All things are poison. It is in the dose that they become poisonous". And Oxygen is no exception. Oxygen is nasty toxic stuff, and living organisms live in an uneasy truce with this substance, having evolved mechanisms over the aeons to protect themselves from it's toxicity. You can kill anything with enough Oxygen. This is why Hydrogen Peroxide is an effective bactericidal. 
Ask any intensivist how comfortable they feel when patients require high levels of Oxygen, even at just atmospheric pressure. As far as DZ is aware there are only two therapeutic indications for hyperbaric oxygen therapy, gas gangrene and carbon monoxide poisoning. Other than this the only effect on lifespan with this practice is to likely shorten it. The lethal dose for humans is not well documented, but 3 atmospheres of 100% O2 is probably a very bad idea, potentially causing convulsions and death. Despite this there are however various sites on the internet extolling the virtues of this therapy, which they offer commercially to a gullible public seeking "wellness"
And the consequences of generating a spark in a hyperbaric Oxygen chamber don't bear thinking about.
