we examined the change in circulatory kinetics due to an increase in intraabdominal pressure by adding pressure quantitatively to the abdominal wall by means of the manchette technique by using mongrel dogs , and obtained the following results : 1 ) by adding to the pressure to the abdominal wall , the pressure of inferior vena cava at the confluence of right and left common iliac veins showed a significantly higher value ( p less than 0.05 ) than those at other 4 areas of the vena cava from just above the diaphragm to the above confluence .
