Fig. 6. Composite left pulmonary vascular pressure–flow plots after left lung autotransplantation (LLA; n = 8) in the conscious state, after preconstriction with U46619, and during propofol anesthesia. Propofol caused pulmonary vasoconstriction (* P < 0.05) when vasomotor tone was increased with U46619. PAP-LAP = pulmonary arterial pressure–left atrial pressure.
