[The gas-exchange properties of membrane blood oxygenators with immobilized heparin].

: Gas-exchange properties of membrane oxygenators (MO) "MOST-122" with immobilized heparin have been studied during 18 open heart surgeries. It has been shown that heparin immobilization on MO surfaces that are in contact with blood is accompanied by enhanced MO ability to oxygenate blood and remove CO2.
