Respirocyte Technology & Hazardous Environment Parsing is an eBook in Deus Ex: Human Revolution. It can be found in the apartment belonging to Seurat. This eBook is required for the Doctorate achievement.
The respirocyte project currently represents the bleeding edge of nano-scale micromachine technology, and while a full 'pure' application of that system is still several years ahead of our current capabilities, at this stage we are capable of implanting a combined interlaced augmentation using basic respirocyte proxies, rebreather technology and enhanced lung musculature synthesis, using electroactive polymers.
The respirocyte itself is an artificial red blood cell, a sphere approxmiately one micron in diameter with a high internal pressure on the order of around one thousand atmospheres; test examples have been constructed using artificial diamond analogues, drawing power from blood glucose. It is theorized that the mature design respirocytes could contain several hundred times more oxygen and carbon dioxide than organic blood cells; in effect, a human being with respirocyte colonies in their bloodstream could hold their breath for long periods.
Combined with microminiature rebreather systems to recycle exhaled breathing gasses and implanted molecular filters, it is theoretically possible for a human so equipped to also resist airborne poisons, particulate contaminants and other toxic environments for short periods.
