Cerebral haemodynamics - Darcy's Law Flashcards
1
Q
Relationship between flow rate, area, pressure gradient, viscosity and height of the column
A
Q = k x A x pressure difference / viscosity x height
2
Q
Simplified darcy’s law
A
flow rate = pressure difference / resistance
3
Q
Compliance functions I
A
Systole Energy Temporarily stored as potential energy. During dyastole, stored potential energy is converted into kinetic energy
4
Q
Advantage of the compliance function I
A
Lowers maximum systolic pressure
Increases cardiac output
5
Q
A
