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 |
