WARNING!
The initial pressure settings are recommendations. It is always appropriate and
prudent to use the lowest possible pressure setting to minimize extravasation and
any other pressure-related injury to the patient.
5.2 How to Operate the AR-6480 in INFLOW ONLY Mode
WARNING!
The extension or patient tubing must be replaced before each new patient and/or
procedure.
1. After adjusting the required pressure using the pressure set buttons
[Table 3, II or V], remove the cap from the patient end of the tubing.
2. Open all appropriate tubing clamps.
3. Activate the pump motor by pressing RUN [Table 3 or VI].
4. Fill the entire length of the tubing with fluid to remove any air bubbles.
NOTE: It is not necessary to remove the air within the sensor chamber [g] on the
pump tubing set.
5. After the air has been purged from the tubing, close the clamp at the
patient end of the tubing. The rollers [13] should stop turning. This is a
safety check to ensure that the sensor system is working properly.
If the rollers do not stop, ensure the clamp is firmly closed.
If the rollers turn continuously, the pressure line connector [e] may
not be functioning properly. Replace the pump tubing.
6. Connect the tubing to the inflow cannula.
NOTE: A high-flow arthroscope sheath should be used for optimum flow
when rinsing through the inflow cannula.
7. Open the clamp on the tubing to release the flow.
Once the set pressure is reached, the pump will reduce flow to maintain
the set pressure. When the pressure drops, the flow automatically
increases until the set pressure is achieved. If the set pressure cannot be
attained, (no fluid restriction at the end of the distal end of the tubing)
flow will not exceed the user setting.
8. When the procedure is completed, close all clamps and disable the
pump motor.
