A prosthetic lung for receipt by a lung space of a patient includes a mass exchange apparatus for use in blood/air mass exchange, an air sac and an air vessel. The mass exchange includes plural blood flow conduits for defining blood flow and a plural air flow conduits for defining air flow. The plural air flow conduits and the plural blood flow conduits at least partially include gas-permeable membrane material and the conduits are arranged relative to each other to enable transfer of oxygen from the air to the blood and transfer of carbon dioxide from the blood to the air. The mass exchange apparatus is provided with at least one first air port and at least one second air port, so that the air flow may be defined therebetween by the plural air flow conduits. The air sac defines an air sac cavity in fluid communication with at least one first air port of the mass exchange apparatus. The air vessel defines an air vessel cavity in fluid communication with at least one second air port of the mass exchange apparatus. The air vessel is provided with an air access port arranged, in use, to enable air flow communication with the trachea of the patient.
