During SSO2 therapy developed by the Irvine, Calif., biotechnology company TherOx Inc., saline is drawn into a chamber in a disposable cartridge inserted into the treatment system. Supersaturated oxygen is sprayed into a second chamber and mixed with the saline.
The patient's blood is circulated through a third chamber where it mixes with the SSO2 saline. The blood-oxygen-saline solution is then directed by catheter into the patient's coronary artery where it infuses the capillary bed and surrounding heart tissue. The procedure takes about one hour.

Median [interquartile range] infarct size was 24.1% [14.4%, 31.6%] at 4 days and 19.4% [8.8%, 28.9%] at 30 days.
re-perfusion injury (damage)が思い浮かぶのだが・・・
