Valsalva maneuver response
The Valsalva maneuver response, when assessed with vascular ultrasound, involves observing changes in blood flow and vessel caliber during forced
Vegetation detection
Vegetation detection in cardiac ultrasound identifies abnormal growths on heart valves or endocardium, often indicative of endocarditis. These irregular masses,
Veno-arterial ECMO
Veno-arterial ECMO (VA-ECMO) is a life-sustaining critical care intervention providing temporary support for severe heart and lung failure. In VA-ECMO,
Veno-venous ECMO
Veno-venous Extracorporeal Membrane Oxygenation (VV ECMO) is a life-support technique used in Critical Care for patients with severe respiratory failure.
Venous mapping
Venous mapping is a crucial ultrasound technique within vascular medicine, meticulously performed to visualize and assess the anatomy and health
Venous obstruction
Venous obstruction refers to a blockage in a vein, impeding normal blood flow back to the heart. This condition can
Venous reflux
Venous reflux, central to vascular health, occurs when valves in veins weaken or fail, causing blood to flow backward, typically
Ventilator-induced changes (US)
Ventilator-induced changes in lung ultrasound (US) refer to alterations in lung tissue and pleura observed during mechanical ventilation. These changes,
