Fig 1 Schematic drawing of the ex vivo lung evaluation system. The lungs, placed in the evaluation box, are connected to the perfusion system and a ventilator. End-tidal CO2, pulmonary arterial pressure (PAP), and left atrial pressure (LAP) are measured. The blood coming out from the left atrium is drained to a reservoir (A), passes a centrifugal pump (B), is deoxygenated in an oxygenator (C) provided with a mixture of gases, passes a flow measurement probe (D) and a leukocyte–arterial filter (E), and is then pumped into the pulmonary artery. F indicates oxygen pressure and temperature sensors, and G, the shunt used to prime the system with Steen solution.
