    side - chemists have been ceaselessly and thanklessly toiling to create fluorocarbons, as described by wiikipedia:

    Fluorocarbons, sometimes referred to as perfluorocarbons or PFCs, are organofluorine compounds that contain only carbon and fluorine bonded together in strong carbon–fluorine bonds.

    Wikipedia - being dominated by lefty-pinko-commies -  makes these compounds sound rather bad.  But if you go to Pubmed, the NIH-sponsored search engine you get a different perspective:

    The problems posed by transfusion of homologous blood have led to the development of substances able to replace the gas transporting properties of blood. Perfluorocarbons (PFCs) emulsions and modified haemoglobin (Hb) solutions have been developed for this goal and are now tested in clinical assays. PFCs are synthetic fluorinated hydrocarbons, capable of dissolving large quantities of oxygen (O2; without binding) at high inspired concentrations of O2, and of delivering this O2 to the tissues. They are administered as emulsions containing particles with a diameter of approximately 0.2 micron, capable of entering the microcirculation. They are eliminated unchanged by the lungs within several days.

    Basically, these miracle chemicals are put into your bloodstream where they carry oxygen for a few days while your body rebuilds your own blood - and, magically, are expirated through your lungs as no longer needed.

      friendly- it sounds like the exhaled gases could be ozone-depleting. Are they?

      •  If that is your main concern about this (0+ / 0-)

        approach, I hope you never learn about nuclear medicine .. . .

        •  EEEK Nuclear bombs in our hospitals!!! (0+ / 0-)

          No but really, I do know that Nuclear Medicine has issues. I just wonder if we could see a brand new form of environmental destruction in the Fluorocarbon blood-substitutes. If they work, they'll be very widely used, and so now's the time to raise whatever concerns we have about them.
