Pulse Transmission Characteristics in the Microcirculution
The steady flow
concept assumed for the
microcirculation is in
accordance with the windkessel theory that peripheral vessels act as stiff
tubes. This would protect the small vessels against sudden surges in
flow and rapid changes in pressure.
With the advent of new technology, particularly the servo-controlled
micropipette device for pressure measurement
methods for velocity recording, studies of the pulse transmission in
capillaries became feasible.
damped, pressure and flow pulses generated by the heart persist into
the pulse transmission path from the ascending aorta
the index finger artery.
