7 ways to evaluate the patient Skin color Temperature Lesions Capillary filling Elevation/ dependency changes Palpation Auscultation
Triphasic qualities Rapid upslope Sharp peak Rapid downslope
Biphasic Doppler signals Rapid upslope Sharp peak Fairly rapid downslope Flow reversal No resumption of forward flow
Monophasic Doppler signals Slow upslope Rounded peak Slow downslope No reversal Non-pulsatile
The higher the viscosity, the _____the resistance to flow higher
Is turbulence more likely to be seen in a bigger or smaller vessel radius? bigger
waveforms post-exercise in an abnormal person will be Slow upstroke with more rounded peak Slow downslope No reverse component
An increase in flow speed _______ the Reynold's number increases
The smallest vessels in the circulatory “tree”. capillaries
Capabilities of Doppler segmental pressures Assess for presence of arterial disease Assess for severity of disease Show approximate location of disease
T or F Segmental pressures cannot discriminate between stenosis and occlusion True
Patient position for Doppler segmental pressures Supine with arms relaxed and at sides Legs at level of heart
