Characteristics of Stage 1 pressure injury
Non blanchable erythema
In darker skin it could look taut and shiny
Characteristics of Stage 2 pressure injury
Grapefruit comparison-peel worn and under side of peel exposed
Pink and red wound bed
Could be blister
Characteristics of Stage 3 pressure injury
Grapefruit comparison-peel gone and white pith exposed
Sub-Q fat exposed
3 skin layers involved. Epi, dermis, sub q
Full thickness
Slough, tunneling or undermining may be present
Characteristics of Stage 4 Pressure injury
Grapefruit- meat of fruit exposed
Tendon, bone, muscle exposed
Full thickness
Tunneling and undermining often present
Risk of osteomyelitis (bone infection)
Unstageable pressure injury
Eschar or slough present that prevents seeing wound depth
Must be debrided before staged correctly
Deep tissue injury
Will be purple or maroon vs the red of stage 1 pressure
May feel different than surrounding tissue
Hydrocolloid dressing facts
Autolytically debrides necrotic wounds
Can stay in place for up to 7 days
Keeps moist
Prevents infection-but does NOT treat an infected wound
Absorbent layer of gel on semi permeable film
Pressure injury stages 1-3
Hydrogel dressing facts
Contributes moisture to wound
Protects and seal
Absorbs small amounts of exudate
Swells as absorbs exudate
Foam and alginate dressing facts
Highly absorbent
Providescompression, padding and protection
No moisture provided
