Movement of blood through a congenitally abnormal or surgically created connection and communication between two circuits, at the level of the atria, ventricles, or great vessels "Shunt" is a physiologic term, in contrast to "connection" which is an anatomic term
{f} shift, divert; alter the course of; move onto a side track (of a train or car); create a channel in order to divert bodily fluids away from a particular body part (Medicine)
This is a catheter like device which is usually surgically implanted within the head or body area It allows excess CSF to drain into another part of the body, usually the abdomen
A calibrated low resistance connected in parallel with the input terminals of a voltmeter in order to enable measurements of large currents It can be internal or external, and typically voltage drops across external shunts are 50 mV or 100 mV
When railway engines shunt wagons or carriages, they push or pull them from one railway line to another. The GM diesel engine shunted the coaches to Platform
In respiratory physiology, a passageway for blood to bypass an organ In a right-to-left shunt, blood passes from systemic veins to systemic arteries bypassing the pulmonary capillaries (so that it does not exchange oxygen or carbon dioxide with the alveoli)
An abnormal flow pattern of blood through the chambers of the heart or through the large arteries leaving the heart A "left-to-right" shunt results in extra blood flow entering the lungs, while a "right-to-left" shunt results in decreased blood flow to the lungs, low oxygen levels and cyanosis A surgically created connection designed to increase the delivery of blood to the lungs The most common types of shunts are named for the physicians who popularized them (Blalock-Taussig, Waterston, Potts, Glenn) A "modified" shunt may involve the use of artificial material, such as Gore-tex®
{i} act of turning aside, act of diverting; bypass, device used to divert an electrical current (Electricity); railroad switch; channel created to divert bodily fluids away from a particular part of the body (Surgery)
A thin, flexible, straw-like device which is implanted in the fluid cavities of the brain to control the build-up of cerebrospinal fluid Shunts most commonly run under the skin from the head to the abdominal cavity
An electrical bypass circuit that proportionally divides current flow between the shunt and the shunted equipment It also allows high current measurements with low-current equipment
a resistive load through which electricity is diverted Often the resistance of a shunt is known precisely and is used to determine amperage by measuring the voltage across it and using Ohm's law (I = V/R)
implant consisting of a tube made of plastic or rubber; for draining fluids within the body a conductor having low resistance in parallel with another device to divert a fraction of the current a passage by which a bodily fluid (especially blood) is diverted from one channel to another; "an arteriovenus shunt"
disapproval If a person or thing is shunted somewhere, they are moved or sent there, usually because someone finds them inconvenient. He has spent most of his life being shunted between his mother, father and various foster families
Also called shorting bars or tie bars These can either be rigid or foam shapes designed to electrically short device leads and reduce the possibility of ESD damage
A conducting circuit joining two points in a conductor, or the terminals of a galvanometer or dynamo, so as to form a parallel or derived circuit through which a portion of the current may pass, for the purpose of regulating the amount passing in the main circuit
a drainage system Spinal fluid flows from a ventricle into a body cavity via a tube Used to relieve increased intracranial pressure caused by brain tumors that block the flow of spinal fluid
System of tubing, most likely including pressure valve and reservoir, used to drain CSF fluid from the ventricles or sub-arachnoid space of the brain into another part of the body, normally the peritoneal space or occasionally the heart
