HVAD
®
Pump Overview
Introduction
120 HVAD® Instructions for Use
6.4 Surgical Implant Procedure (continued)
De-airing Procedure (continued)
CAUTION:
needles have a cutting point which may result in blood leakage and may require repair by suturing.
5. Start HVAD
®
Pump at 1800 RPM by pressing the blue button labeled “START” on the monitor.
6. With the HVAD
®
Pump at 1800 RPM, use TEE to assess air in the left ventricle and aorta.
WARNING! ALWAYS remove all air from the HVAD
®
Pump and its conduits to reduce risk of air embolus.
WARNING!
®
Pump when there is inadequate blood volume in the HVAD
®
®
resulting in a delay in de-airing and possible air embolism.
CAUTION:
®
estimation may not be accurate.
7. After all air is removed, remove the 19-gauge needle and oversew the needle hole with
pledgeted sutures.
8.
9. Gradually increase HVAD
®
cardiopulmonary bypass as tolerated.
NOTE: Increase HVAD
®
Pump speed in increments of 100 RPM with a 20-second interval between speed
Programming the Back-up Controller to Match the Primary Controller
A back-up controller should always be available and programmed identical to the primary
controller. The back-up controller should be programmed before the implant procedure, prior to
patient transfer from the operating room, when the primary controller is replaced, and upon any
parameter change to the primary controller.
Parameters include:
1. Pump speed
2. Hematocrit setting
3. VAD ID/Pump serial number
4. Suction Response setting
5. Controller date and time
6. [Low Flow] alarm limit
7. [High Power] alarm limit
8. Patient ID
For instructions on programming the controller and removing power from the back-up
controller, see Section 6.2.
