5.1 Initial Pressure Settings
W A R N I N G !
The safety and effectiveness of the AR-6480 is verified and documented;
however, the AR-6480 must be used with an awareness of the risk of extra-
articular edemas for patients with pathologically changed articular
capsules and for procedures involving an opening of the capsule (e.g.
lateral release).
Slight swellings have been observed and described in the literature in
cases where roller pumps are used in arthroscopy. This build-up of fluid
can lead to postoperative swellings and pathological changes in patients. It
is of the utmost importance that the surgeon monitors both the system and
the patient closely while the roller pump is in operation.
Always start with the lowest possible pressure to achieve the desired joint
distention. Continue to increase distention pressure until a clear liquid
medium is obtained.
After the DualWave power-up sequence has finalized, the user will be able to
select from four preprogrammed pressure settings for the knee, shoulder, small
joint, and hip joint spaces. Once the icon for the selected joint space has been
pressed, the DualWave will display the appropriate controls and readings on the
TPVD. The pressure presets can be adjusted by entering the MENU, then
Defaults, then Presets. Selecting “done” will save the adjusted preset in memory
until it is changed.
Table 14 specifies the initial pressure settings that are preprogrammed for
surgery. The ideal intra-articular pressure depends on the indications for the
arthroscopic procedure, bleeding tendency, and the possibility of ischemia

All settings are based on the use of a high-flow sheath or secondary inflow portal
(suprapatellar, etc.).
