ADJUSTMENT
A. ADJUSTMENT
1. Open the air valve by twisting it counterclockwise. If your cushion comes with two
valves, open both valves using the same technique. (Figure 7)
2. Attach the rubber hose on the Air Insert
Pump to the end of the valve. Inflate the
cushion insert with the pump until just before the cushion begins to arch. (Figure 8)
3. Remove the pump hose from the valve and close it by twisting it clockwise. (Figure 9)
4. Sit on the JAY Fusion Cushion, with the Air Insert installed, in your normal sitting
position with armrests and footrests properly positioned.
5. Slide your hand beneath your buttocks to locate your lowest bony prominence, usual-
ly the ischial tuberosites. If necessary, your clinician or caregiver should assist you.
(Figure 10)
6. Leaving one hand in place beneath the lowest bony prominence, use the other hand to
open the valve. As air is released from the cushion insert, you will begin to sink into it.
When your fingertips touch its base, close the valve. Approximately 1/2” (13
mm) of air should be between your lowest bony prominence and the base of the
cushion. (Figure 11)
B. IMPORTANT ADJUSTMENT NOTES
• Your JAY Fusion Cushion with Air Insert may have been ordered with two valves, one
on each side of the cushion. If you have two valves, steps 1-6 above should be
repeated for each valve. Two valves indicate that your cushion insert is divided in the
middle. You, your clinician or caregiver should locate the lowest bony prominence on
the same side as the air valve used to adjust the cush-ion.
• You, and your clinicians or caregivers should check the cushion insert daily to ensure
that you have not bottomed out (ie. lost air and are now sitting on the base of the
cushion). If you have bottomed out, the protective value of the cushion insert is lost.
You should also check to be sure the cushion insert is not over-filled with air. The
cushion insert will work best with approximately 1/2” (13mm) of air between you and
its base.
• The Air Insert may be affected by changes in altitude. You may have to repeat steps
1-6 above as you change altitudes.
