HEMODYNAMICS OF RIGHT CIRCULATION IN EWE - NORMAL VALUES

The right cardiac pressure was measured on 24 anesthetized adult ewes (Halothane(TM)) with a Swan Ganz catheter. After a review of the cathe terization technique, the results (mean+/-standard deviation) in mmHg were: right auricle 17+/-5, right ventricle 30+/-6 (systolic) and 12+/ -6 (telediastolic), pulmonary artery 29+/-6 (systolic), 13+/-6 (diasto lic) and 20+/-6 (mean), capillary pressure 17+/-7. We observed slight variations in the pressure curve morphology compared to those found fo r man and the pressures were 5-10 mmHg higher than what is observed in man and slightly higher than those observed in dogs. These results al so demonstrate a great variation between animals.
