Non-blanchable erythema of intact skin
Clear, thin, watery drainage
Watery drainage with small amounts of blood
Force that occurs when layers of tissue slide over each other
WBC enter the blood stream and begin the wound cleaning process
Collagen meshwork continues to strengthen the wound
Death of cells or tissue
Begins shortly after the initial injury where epithelization and collagen form
Force that occurs when two surfaces rub against each other
Partial-thickness skin loss involving the epidermis or dermis
Lack of blood supply to a tissue
Full-thickness skin loss involving damage to or necrosis of subcutaneous tissue
Thick and opaque drainage
Platelets release growth factors which alert cells to begin to repair process
Damage to the skin and underlying tissue due to prolonged pressure
Fresh bleeding
