If you mean the planet Venus. Then the pressure at the planet's surface is about 92 times that at Earth's surface.
If your meaning venous as in blood, that has a systolic & diastolic number. As when the doctor tells you your B/P or blood pressure is for instance 120 over 80.
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
No, atmospheric pressure decreases with altitude.
Gage pressure is the pressure measured relative to atmospheric pressure, while absolute pressure is the total pressure including atmospheric pressure. Gage pressure only considers the pressure above atmospheric pressure, while absolute pressure includes atmospheric pressure as well. This affects pressure measurements in a system because gage pressure readings will fluctuate with changes in atmospheric pressure, while absolute pressure readings will remain constant regardless of atmospheric pressure changes.
Vacuum pressure is the pressure below atmospheric pressure, while gauge pressure is the pressure above atmospheric pressure. Vacuum pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
Normal central venous pressure is in the range of 2-8 cmH2O.
A couple of reasons: surfactant - a detergent - reduces surface tension to a negative value. the plura contains a "vacume" (lower pressure than atmospheric) and pulls the lungs to the chest wall. venous blood partial gas pressure is sub atmospheric.
because the endothoracic pressure is decreased and the venous return to the heart is increased.

The Valsalva maneuver to increase thoracic pressure illustrates the effect of external factors on venous pressure.
Atmospheric pressure
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction

Central Venous Pressure
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
No, atmospheric pressure decreases with altitude.
