The effect of Fluosol-DA on pulmonary vessels.

The infusion of Fluosol-DA will increase the pulmonary artery pressure and the capillary wedge pressure as well as increase the cardiac output. The changes were more marked with the infusion of Fluosol-DA compared to whole blood, Hespander, or Saviosol. Calculated pulmonary vascular resistance decreased with Fluosol-DA infusion and lung water did not increase. We reconfirmed that during infusion of Fluosol-DA, PaO2 increased in many cases and the calculated shunt ratio decreased as a result.
