The invention relates to control of bubble formation in a fluid during extracorporeal circulation. A fluid supply means (111a) is configured to supply fluid to the extracorporeal circuit (111a, 111b, 113, 114, 115, 116), a flow control means (113) is connectable to the extracorporeal circuit and configured to control the flow of the fluid in the circuit; a gas exchange means (114) is connectable to the circuit and configured to gas exchange of the circulated fluid; an antibubble control unit (125) is connectable to an outlet (123) of the gas exchange means and configured to control the total gas pressure over a gas-exchange membrane (118) of the gas exchange means, whereby the amount of gas in the fluid leaving the gas exchange means can be controlled; and fluid return means (115, 116) is connected to the gas exchange means and configured to reintroduce the fluid into the patient.
