Information

Pressure can be generated by an elastic tissue surrounding some accumulated volume. Typically there is a threshold volume, below which the relative pressure is equal to external pressure and the wall of the blood vessels is not stressed. But if the volume rises above this value, the pressure increases proportionally. The slope in this pressure-volume characteristic is called “Compliance”.

• Increassing volume above ZeroPressureVolume (V0) generate positive pressure (greater than external pressure) lineary dependent on excess volume.
• Decreasing volume below CollapsingPressureVolume (V00) generate negative pressure (lower than external pressure) logarithmicaly dependent on volume.
• Otherwise external pressure is presented as pressure inside ElasticVessel.
