What are seat cushions indicated for?
Accomodate impaired sensation
Presence of decubitus ulcers
Stabilize and or accommodate pelvic malalignment
Increase pressure distribution
What must you consider when choosing a seat cushion?
Sensation and mobility (ability to independently reposition
4 different types of cushions
Foam
Gel
Air
Honeycomb (cellular structure)
Advantage of foam
Inexpensive
Light weight
Disadvantage of foam
Decreased pressure relief
Decreased durability
Not washable
Advantage of gel cushion
Low maintenance
Good pressure relif
Washable
Disadvantage of gel cushion
Weight of cushion (car transfer)
Advantage of air cushion (roho)
Superb pressure relief
Washable
Disadvantage of air cushion
High maintenance
Decreased stability
Susceptible to changes in altitude
Advantage of honeycomb (cellular structure)
Pressure relief plus positioning Provides uniform load Perforated for air circulation and moisture evaporation Shear force reduction Washable
Advantage of tilt-in space
Recline and rest Pressure relief (full relief for dependent and independent
Disadvantage of tilt-in space
More complex components and requires head rest
Increased cost
Advantage of reclining back and elevating leg rests
Recline and rest
Provides change in pressure distribution
Disadvantage of reclining back and elevating leg rests
Recline and rest Pressure relief (full relief for dependent and independent
Recline vs tilt-in-space (advantage)
Recline has repositioning for clothing/catheter and head positioning
Disadvantage of Recline vs tilt-in-space
Shear force of recline leads to skin breakdown
Lose posture when turned from reclined position
Why would you use a front strap for tibia on the foot rest?
