Component of bandages - Coggle Diagram

- - - - allow desiccation
      - adherence of exudate, necrotic tissue and wound debris
    - - often painful to remove
      - used when there is enough drainage to soak through tertiary layer
        
        environmental bacteria to wick through and contaminate the wound
      - delay fibroplasia and epithelization
        
        should not be used for prolonged period of time
    - - Wounds that have copious amount of low viscosity exudate, loose necrotic tissue or foreign debris
      - Technique
        
        Place a dry gauze square over the wound, followed by the secondary and tertiary layer
      - How it works
        
        Allows necrotic tissue and foreign debris to adhere to the gauze
        
        while allowing wound drainage to pass through to the secondary layer
    - - higher viscosity exudate and loose debris requiring debridement
      - common in vet med
      - Technique
        
        gauze is applied wet, moistened with
        
        sterile saline, OR
        
        sterile water containing a dilute antiseptic solution, such as 0.05% chlorhexidine diacetate
        
        Dressing allowed to dry before removal
