Mattress Compression Test - Invacare IVC Bariatric Bed User Manual

3.2 Mattress Compression Test

DANGER!
Risk of Death, Injury, or Damage
To avoid injury or damage from misuse or entrapment:
– Proper patient assessment and monitoring, and proper
maintenance and use of equipment is required to
reduce the risk of entrapment. Variations in bed rail
dimensions, and mattress thickness, size or density
could increase the risk of entrapment. Visit the FDA
website at http://www.fda.gov to learn about the risks
of entrapment. Review "A Guide to Bed Safety",
published by the Hospital Bed Safety Workgroup,
located at www.invacare.com. Use the link located
under each bed rail product entry to access this bed
safety guide.
– Refer to the user manuals for beds and rails for
additional product and safety information.
– Patient entrapment from use of bed side rails
may cause injury or death. The Invacare mattress
MUST fit firmly against the bed frame AND bed
side rails to prevent patient entrapment. Follow
the manufacturer's instructions. Monitor patient
frequently. Read and understand the User Manual
prior to using this equipment. Invacare manuals are
available at www.invacare.com or your dealer.
– An increased risk of patient entrapment may occur
over time due to mattress compression. Periodically
monitor gaps between the bed, mattress, and/or bed
rail. Where gaps occur, patient entrapment is possible
and the mattress should be replaced.

1. Remove all bedding from the mattress.
2. Measure the thickness of the mattress (mattressdepth) in an
uncompressed area.
3. Lay a straight edge over the compressed area of the mattress so
each end is roughly at the same height.
4. Measure from the bottom of the straight edge to the lowest point
of the compressed area to find the depth of the compressed
area (compressiondepth).
5. Put the measurements you have obtained into following formula
(compressiondepth divided by mattressdepth multipled by 100)
to determine the amount of compression (compresspercentage):
