Final answer:
To reduce wall motion artifacts on a Doppler tracing, one should increase the high pass filter to remove low-frequency signals while maintaining the integrity of the aortic flow data.
Step-by-step explanation:
To eliminate the appearance of high amplitude signals from wall motion artifacts on the Doppler tracing of the aortic valve while still properly demonstrating aortic flow, you would increase the high pass filter. This setting allows low-frequency signals, which are typically from wall motion artifacts, to be filtered out, while still capturing the higher frequency signals from blood flow within the artery. Adjusting the high pass filter will help to clear up the Doppler tracing without losing the important information about the aortic flow itself.
To eliminate the appearance of high amplitude signals on the Doppler tracing while maintaining the proper demonstration of the aortic flow during a Doppler evaluation of the aortic valve, you should decrease the wall filter settings. Wall motion artifacts are caused by echoes from motion outside the area of interest, such as the heart wall or adjacent structures. By decreasing the wall filter settings, you reduce the sensitivity to these echoes, thus eliminating the appearance of high amplitude signals on the Doppler tracing.
