1. PERFORMING TTFM MEASUREMENTS Before measurement:
During Measurement
1. Select correct application.
1. Place the probe on the graft.
2. Fill in patient data.
2. Check that ACI is green or yellow. If the ACI shows red or orange, try using more gel or use a different probe size.
3. Connect the ECG cable (if applicable).
3. The values can be read when the red baseline is flat and stable.
4. Connect the probe. 5. Choose applicable anatomical location. 6. Check the ACI. This can be done by placing the probe in water. ACI should be green with 90% or above.
4. Save the measurement. The system will save 1 minute retrospectively each time the save button is pressed.
Note To obtain DF% readings, and red/blue color for the systolic/diastolic phases, ECG signals must be provided via an ECG cable. Remember to save the best measurements. Scroll the stored data, and save where the PI, Flow and DF% are representative for the measurement with good ACI.

The System is preset according to the selected application. To change the presets, press the Current Imaging Preset button (9) and choose the correct protocol. The following adjustments can be made: • Change depth (6) • Turn on Color Doppler or Pulsed Wave Doppler (5) • Hide Color (15) • Change position of ROI or PW Gate • Change the velocity scale Press Save to store a 5-second video sequence Note After 5 minutes of inactivity, the system will stop scanning and freeze the image. Press the Start icon (8) to resume scanning.
