What else can I help you with?
Does gauge pressure include atmospheric pressure?
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.
What is the difference between gauge pressure and atmospheric pressure?
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.
Does atmospheric pressure increase with altitude?
No, atmospheric pressure decreases with altitude.
What is the difference between gage pressure and absolute pressure, and how do they affect the measurement of pressure in a system?
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.
What is the difference between vacuum pressure and gauge pressure?
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.
What is central venous pressure?
Normal central venous pressure is in the range of 2-8 cmH2O.
Why do the lungs remain expanded in the normal thoracic?
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.
Why the jugular venous pressure falls during inspiration?
because the endothoracic pressure is decreased and the venous return to the heart is increased.
Does gauge pressure include atmospheric pressure?
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.

What maneuver to increase the thoracic pressure illustrates the effect of external factors on the venous pressure?
The Valsalva maneuver to increase thoracic pressure illustrates the effect of external factors on venous pressure.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
What might an abnormal increase venous pressure indicate?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
What might an abnormal increase in venous pressure indicates?
these factors can increase central venous pressure: decreased cardiac output, increased blood volume, venous constriction,forced expiration, muscle contraction
What does CVP monitor?
Central Venous Pressure
What is the total pressure gauge pressure plus atmospheric 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.
Does atmospheric pressure increase with altitude?
No, atmospheric pressure decreases with altitude.
