ROHO

QUADTRO SELECT
®
Cushion Inflation and Adjustment Guide
The QUADTRO SELECT
®
has four compartments of air cells. When the ISOFLO
®
Memory Control is open, the air flows freely between the compartments. When the
ISOFLO is closed, the air is “locked” within each compartment. The inflation level of each compartment can be separately adjusted. This allows you to correct or
accommodate side-to-side and/or anterior-posterior asymmetries of the pelvis and upper legs. NOTE: Before adjusting the cushion for an asymmetry, you MUST
adjust the air inflation level to the
proper cushion inflation setting
as outlined below.

Hand Check Results
1.
Place the QUADTRO SELECT
®
cushion in the
wheelchair with the air cells facing up and the non-
skid surface of the cover facing down.
2.
Before inflating, you must open the ISOFLO Memory
Control so that all of the air cells inflate. To open,
push green knob toward the unlocked position.
3.
Slide the rubber nozzle of the hand pump over
the inflation valve. Pinch the
nozzle, turn to open the
inflation valve, and overinflate
the air cells.
4.
Remove the hand pump.
•
If you can slightly move your fingertips: the cushion
is at the
proper cushion inflation setting
(½” - 1” air
between the lowest bony prominence and the seat
surface) and no further adjustment required.
•
If you can easily move your fingertips: there is too
much air between the lowest bony prominence and
the seat surface. Open the inflation valve and slowly
release air until you can barely move your fingertips,
then close the inflation valve.
•
If you cannot move your fingertips at all: there is too
little/no air between the lowest bony prominence
and the seat surface. Open the inflation valve and
slowly add air until you can slightly move your
fingertips, then close the inflation valve.
