Abstract:
It was an dideal model of respiratory distress syndyomeinduccd in 59 rabbits by Ⅳ oleic acid injection. Pulmonary hemodynamics, cardiac impedance paramcters were measured, microemboli and leukocytcs were abtained directly from the pulmonary microcirculation by use of the retrograde perfusion method. The results showed that pulmonary hemodynamics were changed significantly, but did not correlate with development of pulmonary edema. It was found that basic impedance (Zo) increased, stroke volume (SV), cardiac output (CO) and cardiac index (CI) all decreased (P
