We use abdominal doppler to asses the ______________________ of vessels CORRECT ANSWERS: We use abdominal doppler to asses the *patency* of vessels We use abdominal doppler to rule out ______________________ _________________ CORRECT ANSWERS: We use abdominal doppler to rule out *arterial stenosis* what are 3 forms of Arterial Stenosis? CORRECT ANSWERS: - Atherosclerosis: narrowing of vessel - Fibromuscular Dysplasia: twisting of blood vessels - Even Compression from a mass could cause Arterial Stenosis Abdominal doppler can determine flow __________________________ CORRECT ANSWERS: Abdominal doppler can determine flow *direction* For Abdominal Doppler what frequency and transducer do we use? CORRECT ANSWERS: For Abdominal Doppler we use a *2.5-5 Megahertz Phased Array Transducer* ____________ frequency and ______________ sample gate are BEST for abdominal doppler imaging CORRECT ANSWERS: *Low Frequency* and *Large Sample Gate* are BEST for abdominal doppler The Patient should fast for ___ to ____ hours to reduce abdominal bowel gas CORRECT ANSWERS: The patient should fast for *8-12 hours* to reduce abdominal bowel gas What are some limitations of abdominal doppler? CORRECT ANSWERS: - bowel gas - depth of vessel - size of vessels - hard to get good doppler angles - body habitus Normal IVC ranges from ____ to ____ mm during quiet respiration CORRECT ANSWERS: Normal IVC ranges from *5 to 25mm* during quiet respiration Distal IVC is _________ velocity, pressure and phasic flow, which varies with respiration. CORRECT ANSWERS: Distal Aorta is *Low* velocity, *Low* pressure, and *Low* Phasic Flow which varies with respiration. Proximal IVC somewhat of a pulsatile flow pattern due to ______________ _________________ pressure changes occuring during each cardiac cycle CORRECT ANSWERS: Proximal IVC somewhat of a pulsatile flow pattern due to *Right Atrial* pressure changes occuring during each cardiac cycle
