Investigating the effects of cyanide poisonning in Norns

While I was messing around C2 the other day, I was following a Grendel around in an unpopulated test world, and it suddenly dropped comatose with no warning signs.

All his organs had brutally stopped for no apparent reason,he had various food at hand and a full life bar minutes ago.A quick overview of it's bloodstream showed an obvious and fatal cyanide poisoning.So I took the opportunity to fully investigate the mechanisms of cyanide poisoning and the appropriate cure.

So what exactly happens during Cyanide poisoning in C2, and how do you counteract that really severe condition ?
