|
Mechanical force that increases external pressure on the body to improve fluid balance and circulation or to modify scar tissue formation |
Compression |
|
|
You improve fluid balance by increasing this in the interstitial space |
Hydrostatic pressure |
|
|
This type of compression maay improve circulation more effectively |
Intermittent compression |
|
|
This pushes fluid out of blood vessels |
Hydrostatic pressure |
|
|
This keeps fluid inside the blood vessels |
osmotic pressure |
|
|
Fluid rich in protein, water, and macrophages that is pushed out of veins into the interstitial space |
Lymphatic fluid |
|
|
mechanical obstruction of the veins by a tumor or inflammation can result in |
venous insufficiency (peeripheral edema) |
|
|
Most common cause of venous insufficiency; inflammation of veins |
phlebitis |
|
|
Acts as accessory channel; returns the fluids to the blood circulation |
Lymphatic system |
|
|
Low albumin, lymphatic obstruction, abnormal vessel distribution, and reduced activity can cause |
lymphedema |
|
|
Blood clot in the deep veins |
Deep venous thrombosis |
|
|
Cornerstone of treatment of venous statis ulcers |
Compression therapy |
|
|
Areas of tissue breakdown and necrosis that occur in areas of impaired venous circulation |
Venous statis ulcers |
|
|
Common complication of deep burns and otheer extensive skin and soft tissue injuries |
Hypertrophic scarring |
|
|
Compression should not be applied if the ABI is less than |
0.8 |
|
|
(static/intermittent) can be applied immediately after trauma |
static |
|
|
exerted when it is put on a stretch |
Resting pressure |
|
|
Produceed by active muscles pusing against an inelastic bandage and is only produced when pt moves their musclees |
Working pressure |
|
|
Bandages that provide the greatest resting pressure as they exert the greatest restoring force |
Long-stretch bandage |
|
|
Bandages that are useful during exercise when the activity of the musclees results in high working pressure; do not control edema effectively or improve circulation |
Short-stretch bandages |
|
|
Bandage that uses a combination of elastic and inelastic layers to apply moderate to high resting pressure |
Multilayered bandage systems |
|
|
A semirigid bandage formed of zinc oxide-impregnated gauze used to exert working pressure; applied to the lower extremity; used for venous statis ulcers |
Unna's boot |
|
|
Compression should be greatest (proximally/distally) and gradually decrease (proximally/distally) |
distally, proximally |
|
|
provide low compression force of 16 to 18 mmHg to prevent DVT's in bedridden patients |
Antiembolism stockings |
|
|
How many mmHg to use for scar tisssue control? |
20 to 30 mmHg |
|
|
HOw many mmHg to use for edema control? |
30-40 mmHg |
