In recent decades many research effort has been expended in the field of noninvasive, continuous blood pressure (BP) estimation by cardiovascular surrogate parameters, mainly the pulse transit time (PTT). Due to differences in the measurement setup and in the consideration of important physiological aspects, however, there is a multitude of inconsistent statements about the BP tracking capabilities of the parameter PTT in literature. For the purpose of comparing the PTTs on different arterial segments regarding their suitability for central BP estimation - with or without the influence of important physiological aspects - an appropriate clinical trial has been conducted, whereas significant differences could be observed.
