Red = healthy regeneration
Yellow = presence of purulent drainage
Black = presence of eschar that hinders healing and requires removal
```
Red--cover
Yellow--clean
Black--debride, remove necrotic tissue
43
for drainage from a wound, what should you document and look for?

Composition is mostly water, gels after contact with exudate, promoting autolytic debridement and cooling
Rehydrates and fills dead space
Might require secondary occlusive dressing
For infected, deep wounds or necrotic tissue
Provides moist wound bed
Not for moderate to heavy draining wounds
Soothing and can reduce wound pain
Prevents skin breakdown (sacrum)

Hydrocolloid dressing
Nutritional supps
Admin analgesics
--Stage 3: Full thickness skin loss
Visible adipose tissue with poss granulation tissue and epibole (wound edges appear rolled under), some slough and eschar
No exposed underlying tissue
Some undermining or tunnel possible
Treatment
clean/debride wound
Use Prescribed dressing, surgical intervention, proteolytic enzymes
Nutrition supps
Admin analgesics
Admin antimicrobials (topical or systemic)
--Stage 4: Full thickness skin and tissue loss
Skin and tissue loss with cartilage, bone, fascia, muscle, ligaments or tendon exposed in the wound
