medical nanites

Known facts

near-drowning-triggers-oxygen-and-emergency-promptPulled from the water, John gets a HUD alert — near-drowning detected, nanites supplying oxygen directly to the bloodstream, five hours of reserve before he must breathe — and would he like to contact emergency services, or activate first-aid mode to help others? He declines both and disables future emergency prompts.STD:FWH:Ch 15
carbon-replenishment-via-charcoalThe nanites are replenished by ingested carbon; John casually chews the burnt end of a stick to top them up, using taste-bud hacks to pass the flavour off as buttered toast.STD:FWH:Ch 16
person-to-person-emergency-transferJohn saves Ealstan by deactivating the plating on his own palm, cutting it open, pressing the open wound to the arrow wound and triggering an emergency person-to-person nanite transfer — about ninety percent of his colony leaving his bloodstream for Ealstan's to suture, scrub, and rebuild tissue on the spot. The cost on his own side is a forty-eight-hour stretch with depleted immunities and a hard floor of about five percent the system will not let him cross.STD:FWH:Ch 22
