Hypothesis-generating in anesthetized dogs; prospective human studies needed before clinical arterial compliance use.
Swalen et al. (2005) studied Healthy (animal model) (n=11). Automated PU-loop algorithm vs. Manual determination by eye was evaluated on Difference in wave speed determination between automated algorithm and manual method (2.6% average difference). A new automated algorithm for determining wave speed using the PU-loop method produced results that differed by an average of 2.6% compared to conventional manual determination by eye.
