Central Venous Pressure
The central venous pressure or right atrial pressure is the pressure of the blood in the thoracic vena cava near the right atrium. The pressure reflects the amount of blood that return to the heart and can be pumped back through the body.
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
because the endothoracic pressure is decreased and the venous return to the heart is increased.

The normal partial pressure of oxygen in arterial blood is 75-100 millimeters of mercury. In comparison the partial pressure of oxygen at sea level is 750 millimeters of mercury.
The Valsalva maneuver to increase thoracic pressure illustrates the effect of external factors on venous pressure.
