MEDISTIM MiraQ System Quick Manual

Quick Guide - MiraQ™ System

1. PERFORMING TTFM MEASUREMENTS

Before measurement:
1. Select correct application.
2. Fill in patient data.
3. Connect the ECG cable (if applicable).
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.
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.

During Measurement
1. Place the probe on the graft.
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. The values can be read when the red baseline is flat and
stable.
4. Save the measurement. The system will save 1 minute
retrospectively each time the save button is pressed.

1. Make sure the locking lever is in the unlocked position
(the upper position).
2. With the probe cable to the right, insert the connector
into the system in one smooth horizontal motion.
3. When the probe is completely inserted, move the lever
into the locked position (lower position).
4. When removing the probe, hold the connector while
moving the locking lever into the unlocked position, and
gently pull it out.
