WebNormal CVP in patients can be measured from two points of reference: [citation needed] Sternum: 0–14 cm H 2 O Midaxillary line: 8–15 cm H 2 O CVP can be measured by connecting the patient's central venous catheter to a special infusion set which is connected to a small diameter water column. WebPortal hypertension is defined as a hepatic venous pressure gradient (HVPG) (the difference between portal-vein pressure and hepatic-vein pressure) greater than 5 mm Hg, but usually become clinically significant when this gradient reaches 10 mm Hg. Portal venous pressure normally ranges from 7 to 10 mm Hg.
