-In a normal RA pressure collapses the VCI in 80% of the cases, >40% (measured at inmonding hepatic vein). ±40% collapse VCI corresponds to a pressure of 8 - 10mmHg . At a collapse of 60-70%, the pressure in the VCI most often 2- 4mmHg. At a collapse <40%, the VCI pressure > 10mmHg (85%). When dilated , not collapsing VCI can pressure 20 - 25mmHg are .
