DVT423-TB2

USI DMS Lower Extremity Arterial Doppler

QuestionAnswer
What causes the greatest change in blood flow? The radius of the vessel
Where is the highest pressure in the arterial system? Left ventricle
What affects spectral waveforms? Sample volume size and position
What type of flow occurs during flow acceleration in systole or at origins of vessels? Plug flow
If the diameter of a vessel determines the amount of friction, then what happens to friction and flow if the radius gets smaller? Friction is greater and flow is less
Bladder pressure cuff size should be what percentage wider than the limb diameter? 20%
When using cuff application, which cuff method gives more accurate pressure and which gives more accurate disease location? 3-cuff method gives more accurate pressures and 4-cuff method gives more accurate disease location
What order should segmental pressures be done in? Brachial, ankle using higher pressure of DP or PTA, calf or below knee, lower thigh or above knee, then high thigh
