1. Distal Pulse amplification impedance and harmonic resistance of vascular tree
periphreal a line = high systolic, low diastolic
central a line = lower systolic, higher diastolic
MAP is accurate
2. Ohm's Law Pressure ditterence/Resistance=Flow
3. Reynold's Number Re = (v × d × ρ)/n
v = velocity
d = diameter
ρ = density
n = viscosity
4. Poiseulle's law •Poiseuille's Law
-Describes viscosity and laminar flow
F=(πr4ΔP) / (8ήl)
• ΔP à change in pressure (P1 - P2)
-Also called hydrostatic pressure gradient
• R à radius
-Has the most ettect on flow
• ή à viscosity
• l à length
5. Efferent SNS •SHORT preganglionic neuron
• LONG postganglionic neuron (PNS is opposite)
1/6
, • Pre-SNS fibers
-B (myelinated fibers) fast impulse fibers
-Preganglionic fibers synapse in the same level sympathetic chain
2/6
