Assessment of vascular size and of its phasic changes by ultrasound is important for the
management of many clinical conditions. For example, a dilated and stiff inferior vena cava …

The inferior vena cava (IVC) is the largest vein in the body. It returns deoxygenated blood to
the heart from the tissues placed under the diaphragm. The size and dynamics of the IVC …

Interest in soft actuators has increased enormously in the last 10 years. Thanks to their
compliance and flexibility, they are suitable to be employed to actuate devices that must …

Objectives Inferior vena cava (IVC) pulsatility quantified by the Caval Index (CI) is
characterized by poor reliability, also due to the irregular magnitude of spontaneous …

High values of the portal vein pulsatility index (PI) have been associated with adverse
outcomes in perioperative or critically ill patients. However, data on dynamic changes of PI …

Ultrasound (US) scans of the inferior vena cava (IVC) provide useful information on the
volume status of a patient. However, their investigation is user-dependent and prone to …

Pulse wave velocity in veins (vPWV) has recently been reconsidered as a potential index of
vascular filling, which may be valuable in the clinic for fluid therapy. The measurement …

Abstract Objectives Pulse Wave Velocity (PWV) is theoretically affected by the magnitude of
the PW (PWm), in veins as well as in arteries, but, to our knowledge, this possibility has …

Ultrasonic transit time (TT)-based local pulse wave velocity (PWV) measurement is defined
as the distance between two beam positions on a segment of common carotid artery (CCA) …

There has been a growing interest in assessing pulse wave velocity (PWV) in the veins with
studies highlighting their potential in elucidating the vascular indices such as the venous …
