Key result
Analytical and experimental data show that determining the effective length of the arterial system yields an infinite number of exact solutions, none of which necessarily relate to actual reflection sites.

Caution against using effective arterial length for clinical wave reflection assessment; leaves open reliable site localization in research models.
The concept of a single effective length for the arterial system is mathematically indeterminate and does not reliably identify actual pulse reflection sites.
Campbell et al. (1989) studied Arterial system physiology. Determination of effective length (L) of the arterial system was evaluated on Effective length (L) and terminal impedance. Analytical and experimental data show that determining the effective length of the arterial system yields an infinite number of exact solutions, none of which necessarily relate to actual reflection sites.
