46 - Skin integrity/Wound Care Flashcards
Blanching
skin turns lighter colour when pressured then reutrns to normal colour
hyperemia
an excess of blood in the vessels supplying an organ or other part of the body.
Pressure intensity
amount of pressure needed to close capillary, especially susceptibility if reduce sensation and can’t shift to offload pressure, tissue death may occur
Tissue tolerance
ability of tissue to support pressure
Pressure duration
assess amount of pressure and how long the pressure occurs
Shear
force exerted parallel to skin. Skin adheres to surface and muscle/bone slide across the surface
Shear causes DEEP tissue damage, friction causes surface damage
Tissue perfusion
amount of O2 reaching tissue cells (diabetes is a risk factor)
Granulated tissue
red/moist shows that it’s healing
Slough
stringly and yellow/white, attached to wound bed needs to be removed
Eschar
brown/black necrotic tissue, must be removed
Periwound
the whole area outside of the wound, is dry and clean.
raditionally limited to 4 cm outside the wound’s edge but can extend beyond this limit if outward damage to the skin is present
Wound
A disruption of the integrity and function of tissues in the body
Acute
caused by surgical incision. Heal in orderly manner
Chronic
caused by vascular compromise and fail to heal properly
Primary intention
wound that’s closed with sutures/staples, minimal scarring
Secondary intention
wound edges don’t approximate (not pulled together), ex in pressure injury or when tissue is removed. Healed by filling in with scar tissue. Increased risk of injection since its open
