Key result
Dual-pressure recording with distal occlusion successfully measures canine arterial propagation, showing phase velocities of 9-11 m/sec.
Why the study?
Previous methods for determining arterial pulse transmission characteristics required recordings of three or four variables, complicating measurement and analysis.
Population
Common carotid arteries of nine dogs
Comparison
New method using two pressure recordings with distal arterial occlusion vs previous methods requiring three or four variables
Design
Preclinical experimental study

May enable precise arterial impedance assessment in animal models; leaves open translation to human clinical use.
An improved method using two pressure recordings and distal occlusion successfully determines the complex propagation coefficient and characteristic impedance of arteries in vivo.
Busse et al. (1979) studied Arterial pulse transmission characteristics (n=9). Improved method using two pressure recordings with distal occlusion vs. Previous methods requiring three or four variables was evaluated on Complex propagation coefficient (damping constant and phase constant), phase velocity, and characteristic impedance. An improved method using two pressure recordings with distal occlusion successfully determined arterial propagation coefficients in dogs, yielding phase velocities of 9-11 m/sec.
