CHECKING FOR BOTTOMING OUT, J2 J2 DC.
Bottoming out occurs on a J2 J2 DC cushion when you
displace the fluid out from underneath your seat bones,
which leaves you sitting on the foam base. It sometimes
occurs on very thin individuals, people using recliner
wheelchairs, people who slouch when sitting or if using
a cushion that is too wide. When bottoming out occurs,
increased pressure is loaded onto the ischials and coccyx
increasing the risk for skin breakdown.
To check for bottoming out, sit on the cushion without the
cover for a minimum of two minutes. Transfer up and off
the cushion (or have someone help you transfer), trying
not to disturb the fluid underneath you. Push down in the
depressions on the pad where your ischials (seat bones)
and coccyx (tailbone) were. You should have to push
through at least 10 mm (1/2”) of fluid before you feel the
firm cushion base below.
If the cushion is properly positioned and the footrests are
properly adjusted, and there is not at least the minimum
10 mm (1/2”) of fluid, the cushion is bottoming out and
should not be used.
If you are bottoming out, discontinue use of the cushion
and see your clinician. Usually bottoming out is easily
solved by using fluid supplement pads (part# F119). Call
your local authorised supplier to see if this appropriate for
you.
NOTE:
We recommend using a JAY® Adjustable Solid
Seat in place of your wheelchair upholstery or a J2 Solid
Seat Insert in addition to your upholstery. It will optimize
the performance of your J2 J2 DC Cushion and help
provide better positioning for you.
WARNING:
Failure to check the Pressure Relief Pad for bottoming out
can result in skin redness or skin breakdown.
