|---|---|---|---|---|---|
| a protein substance that adds strength to a healing wound | show 🗑
|
||||
| show | Pressure Ulcer(decubitus ulcers, pressure sores, and bedsores)
🗑
|
||||
| to lose color (test the skin integrity of the circulation performed by applying and then quickly releasing pressure. The "blanched" area should regain pink color quickly OR failure to do so suggest impaired blood flow to area). | show 🗑
|
||||
| inadequate blood supply to tissue | show 🗑
|
||||
| show | tissue hypoxia
🗑
|
||||
| show | induration
🗑
|
||||
| skin flushes bright red when pressure to area is relieved; extra blood rushes to area to compensates for ischemic period | show 🗑
|
||||
| show | abnormal reactive hyperemia
🗑
|
||||
| show | eschar
🗑
|
||||
| removal of devitalized tissue; allows wound to heal and removes the medium for bacterial growth; 4 types: sharp, mechanical, enzymatic and autolytic | show 🗑
|
||||
| show | cause of pressure ulcer
🗑
|
||||
| alter skin characteristics or O2 delivery capabilities: nutrition, age, circulation, underlying health status(mobility, impaired sensation( spinal cord injury, coma, stroke), malnutrition, aging...) | show 🗑
|
||||
| mechanical force from dragging across coarse surface | show 🗑
|
||||
| show | shearing
🗑
|
||||
| macerates (soften by sleeping in fluid) the skin ( often, urine and feces and MOISTURE decreases amt. of pressure required to produce ulceration. | show 🗑
|
||||
| extensive tissue loss edges not approximated; heal from inner layer to outer layer by granulation; ( ex. pressure ulcer, infected wound). | show 🗑
|
||||
| show | tertiary intention
🗑
|
||||
| show | inflammatory
🗑
|
||||
| "regeneration"- ( day 5-21); fill defect and resurface skin; collagen forms; granulation occurs. | show 🗑
|
||||
| show | maturation
🗑
|
||||
| show | nutritional needs for preventing impaired skin integrity
🗑
|
||||
| show | skin care needed for impaired skin integrity
🗑
|
||||
| show | frequent positioning turn Q 2 hrs ( for impaired skin integrity)
🗑
|
||||

|
||||
| show | transparent films
🗑
|
||||
| show | absorption dressings
🗑
|
||||
| show | hydrogels
🗑
|
||||
| localized injury to the skin and/or underlying tissue usually over a bony prominence | show 🗑
|
||||
| show | two types of pressure ulcers
🗑
|
||||
| show | pelvis and heels
🗑
|
||||
| pressure blocks blood flow leads to inflammation leads to tissue death leads to tissue necrosis | show 🗑
|
||||
| intact skin with non-blanchable redness of localized area usually over a bony prominence dark pigmented skin may not have visible blanching; its color may differ from the surrounding area | show 🗑
|
||||
| show | stage2
🗑
|
||||
| full thickness tissue loss, subcutaneous fat may be visible but bone, tendon or muscle are not exposed slough may be present but does not obscure the depth of tissue lossmay include undermining and tunneling | show 🗑
|
||||
| show | stage 4
🗑
|
||||
| cannot see the base of the wound full thickness tissue loss in which the base of the ulcer is covered by: slough(yellow, tan, gray, green, or brown) and/or eschar(tan, brown, or black) | show 🗑
|
||||
| purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue from pressure and/or shear | show 🗑
|
||||
| show | primary intention
🗑
