[Perfusion of the isolated heart using ftoksilol, an emulsion of perfluorocarbons]

The coronary vessels of the rat isolated heart were perfused with ftoxycol containing 10 v% of tetrafluoromethane and with isotonic salines used as control. It was shown that ftoxycol is capable of adding, transporting and liberating oxygen. However, oxygen consumption did not differ from control in spite of the fact that oxygen amount in ftoxycol was 2 times greater as compared to control. Perfusion with ftoxycol was found not to change contractility of the rat isolated heart.
