BALANCE Air Insert Rev.B
ADJUSTMENT
1. Open the air valve by twisting it anticlockwise. If your cushion comes
with two valves, open both valves using the same technique. (Fig. 7)
2. Attach the rubber hose on the pump to the end of the valve. Inflate
the cushion insert with the pump until just before the cushion begins
to arch. (Fig. 8)
3. Remove the pump hose from the valve and close it by twisting it
clockwise. (Fig. 9)
4. Sit on the Balance 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, usually the ischial tuberosites. If necessary, your
clinician or caregiver should assist you. (Fig.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” (13.0 mm) of air should be
between your lowest bony prominence and the base of the cushion.
(Fig. 11)
IMPORTANT ADJUSTMENT NOTES
• Your Balance 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 cushion.
• You, 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” (13.0 mm) 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.
