Support Surface Selection

Question 1

Active support surface

Answer 1

Powered
Changes distribution automatically
High-risk patients
When manual repositioning NOT possible
*Alternating pressure mattress

Question 2

Reactive support surface

Answer 2

Powered or non-powered
Changes distribution in response to pt body
When manual repositioning IS possible
*Foam, air, gel

Question 3

Closed cell foam

Answer 3

Non-permeable
0 gas/liquids pass through foam (pro)
> skin temp = dissipation of body heat (con)

Question 4

Open cell foam: elastic

Answer 4

Permeable
> density = durability
Single use (0 use if incontinence issues)
Should be 3 in thick

Question 5

Fluid support surface

Answer 5

Air, H2O, viscous fluid
No shape
Yields to external pressure

Question 6

Air Fluidized (AF) support surface

Answer 6

High air loss
> immersion & envelopment
Good for pt w/ flap

Question 7

Alternating Pressure (AP) support surface

Answer 7

Redistribution via cyclic changes

Active support surface

Question 8

Low Air Loss (LAL)

Answer 8

Flow of air to manage heat & humidity of skin

Question 9

Existing ulcer support choice

Answer 9

Stage II - IV = Active support surface w/ AP feature or reactive support surface w/ LAL or AF
