Abstract:
1. A method for perfusing a lung ex vivo, comprising: connecting the lung within a fluid perfusion circuit, flowing a perfusion fluid into the lung through a pulmonary artery interface and away from the lung through a pulmonary vein interface, providing a respiratory gas to the lung for use in metabolism by the lung, the respiratory gas having a pre-determined composition of oxygen, ventilating the lung through a tracheal interface, and measuring a level of an arterial-venous (AV) oxygen gradient between the perfusion fluid flowing into the lung and flowing out of the lung, wherein the perfusion fluid flowing into the lung includes a first gas component at a substantially constant first composition, and the perfusion fluid flowing away from the lung includes the first gas component at a substantially constant second composition.
