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.
After overinflating the cushion, perform a hand check to
adjust to the
proper cushion inflation setting:
QUADTRO SELECT setup
Hand check results
Inflate and adjust
the ROHO QUADTRO
SELECT cushion for a new individual.
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 will inflate. Push the
ISOFLO 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.
QUADTRO SELECT adjustment
Check
the inflation level daily
by performing a hand check.
Re-adjust
the inflation level only as
needed (typically every 3-4 months).
Proper cushion inflation setting
½” – 1” (1.5 cm – 2.5 cm)
— 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 is needed.
— If you can easily move your fingertips: there is too
much air between the lowest bony part prominence
and the seat surface. Open the inflation valve and
slowly release air until you can barely move your
fingertips, then close the 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 valve.
See reverse side for instructions on how to adjust
QUADTRO SELECT for postural asymmetries.

4. Remove the hand pump.
1. The individual should sit
in the chair in their usual
position. The cushion
should be centered
beneath the individual.
2. Perform a hand check:
a. Slide your hand between
the cushion and the
individual. Lift the leg
slightly and feel for the
lowest bony prominence,
and then lower the leg to
a sitting position.
b. Open the valve to remove
air, keeping your hand
beneath the individual’s
lowest bony prominence.
c. Release air until you
can slightly move your
fingertips. Close the valve.
