Varicose veins tend to run in families, and anything that increases venous pressure in the legs makes them worse.
12.
AJR is a test for measuring jugular venous pressure ( JVP ) through the distention of the internal jugular vein.
13.
Intravenous etilefrine increases the pulse rate, cardiac output, stroke volume, central venous pressure and mean arterial pressure of healthy individuals.
14.
.. . that "'Beck's triad "'of arterial hypotension, raised jugular venous pressure and muffled heart sounds is pathognomonic of cardiac tamponade?
15.
In bypassing the flow-resistant liver, the net result is a reduced pressure drop across the liver and a decreased portal venous pressure.
16.
In late stage, the redistribution becomes ineffective, there is decrease in cardiac output, ineffective preload handling and elevation of central venous pressure.
17.
The rising central venous pressure is evidenced by diastolic filling of the right ventricle, due to pressure from the adjacent expanding pericardial sac.
18.
Decreased portal venous pressure in turn lessens congestive pressures along veins in the intestine so that future bleeding is less likely to occur.
19.
On an otherwise healthy individual, the jugular venous pressure remains constant or temporarily rises for a heartbeat or two, before returning to normal.
20.
In hemodialysis centers, ultrafiltration takes place on the hemodialysis machines when the venous pressure is greater than the transmembrane pressure ( TMP ).
