VERIFY VENOUS & ARTERIAL PRESSURE DISPLAYS (ZERO & GAIN).
Line 7
Place the machine in Dialysis mode and select the Home screen tab. Clear all blood
alarms.
VENOUS PRESSURE CHECK
1. Verify that the venous pressure bargraph indicates 0mmHg when the venous
pressure monitor port is open to atmosphere.
2. Attach a syringe and an external pressure gauge to the venous pressure monitor port
using a T fitting.
3. Use the syringe to create a pressure reading of 400mmHg on the external pressure
gauge. While holding this pressure, verify that the venous pressure bargraph
indicates 400mmHg.
NOTE: Calibration must be performed if the venous pressure display values are not
within tolerance.
ARTERIAL PRESSURE CHECK
1. Verify that the arterial pressure bargraph indicates 0mmHg when the arterial
pressure monitor port is open to atmosphere.
2. Attach a syringe and an external pressure gauge to the arterial pressure monitor port
using a T fitting.
3. Use the syringe to create a pressure reading of 200mmHg (400mmHg for a post
pump) on the external pressure gauge. While holding this pressure, verify that the
arterial pressure bargraph indicates the same value.
NOTE: Calibration must be performed if the arterial pressure display values are not
within tolerance.
Line 8: BLOOD PUMP TUBING DIAMETER: Determine the diameter size of units blood
pump tubing segment. Open the blood pump door. The blood pump display will show
the selected tubing diameter. If not correct, press the [
pump simultaneously. The tubing diameter value will flash. Use the [
to change to the correct tubing diameter. When correct press the [Start/Stop] key to
save the setting. The display will stop flashing and the new diameter will be displayed.
Record this diameter on the Installation Checklist.
