these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
An abnormal increase in venous pressure may indicate a problem with one of the heart valves. It could also mean that the person is on medication that causes higher blood pressure.

The Valsalva maneuver to increase thoracic pressure illustrates the effect of external factors on venous pressure.
a abnormal vein in the brain
Normal central venous pressure is in the range of 2-8 cmH2O.
Increases venous return, which increases stoke vol dat increase CO dat increases Mean arteriol pressure
venous insufficiency
because the endothoracic pressure is decreased and the venous return to the heart is increased.
Contraction of veins would increase venous return to the right atrium. It would increase the efficiency of the heart pumping.
Central Venous Pressure
Jugular venous distension is the visible bulging of the jugular veins in the neck. It can indicate increased pressure in the right side of the heart or in the superior vena cava. It is commonly seen in conditions like heart failure, cardiac tamponade, or constrictive pericarditis.
There will be higher pressure in the left atrium, when there is mitral stenosis. There will dilatation of the left atrium as well as there will hypertrophy of the left atrium. There will raise in the pulmonary veins. This will lead to pulmonary edema. This will eventually lead to high pressure in pulmonary arteries. That is called as pulmonary hypertension. The pressure in right ventricle will increase. Then the pressure in the right atrium will increase. Then the pressure in the systemic venous side will increase. This will lead to right sided heart failure.
