5-2-2. Items of Particular Note For blood flow velocity measurement: When recording an arterial flow Doppler waveform (pulse method), if the Doppler incident angle exceeds 60× the measurement error becomes large. The measured values of the blood flow values obtained using this equipment are the absolute values displayed on the observation monitor. They are controlled as positive and negative values for the purpose of calculating the arithmetic index. If the display of each measured value in a report is set to "Average" in a preset, the positive and negative values are added together and displayed as a mean value. Consequently, when performing multiple measurements of blood flow on the blood flow waveform drawn using the color Doppler method as a guide, use identical recording conditions (forward and reverse flow directions) for all of the blood flow waveforms in order to correctly display each of the arithmetic values arranged in the report.
