Flashcards in Doppler Deck (19):
The direction that a fluid is travelling.
The rate of change of the displacement, the difference between the final and initial position of an object.
A flow with periodic variations
Blood moves with a varying velocity, such as changes that occur with respiration.
When blood moves at the same speed
A way to describe venous or arterial flow that moves in a uniform direction and moves in concentric rings
Flow with all fluid portions traveling with the SAME flow speed and direction.
Any flow that is not in a uniform direction; chaotic, random blood flow moving at different speeds and different directions.
The unusual sound that blood makes when it rushes past an obstruction in an artery when the sound is auscultation.
A palpable vibration.
A dimension less quantity that is used to help predict similar flow patterns in different fluid flow situations.
Reynolds Number (Re)
Any change in energy over time or space.
Kinetic, Pressure, Gravitational
Forms of energy.
Viscous, frictional, inertial
Energy losses in circulation.
An abnormal narrowing of a blood vessel.
An increase in the speed of a fluid occurs simultaneously with a drop in pressure.
The current through a conductor between two points is directly proportional to the potential difference across the two points
In a fluid at rest, all frictional stresses vanish
