Q

Hydrostatic pressure

A

Pressure exerted by a fluid, for example, in the bv. Determined by the force of the heart and gravity and contributes to movement of fluid into or out of bv and lymphatics.

Q

Hypertrophic scarring

A

Excessive scarring with raised and ridged appearance that does not extend beyond the boundaries of the original site of skin injury. This type of scar has poor flexibility and can result in contract urges or poor cosmesis

Q

Short stretch bandage

A

A bandage w low elasticity and 30-90% extension that provides low resting pressure but high working pressure during muscle activity.aka low stretch bandage

17
Q

Static compression

A

Steady application of pressure

18
Q

Unna’s boot

A

A semirigid bandage made of zinc oxide impregnated gauze that is applied to the lower extremity to exert pressure

19
Q

Venous insufficiency

A

Decreased ability of veins to return blood to the heart

20
Q

Venous stasis ulcer

A

An area of tissue breakdown and necrosis that occurs as a result of impaired venous return

21
Q

Working pressure

A

Pressure produced by active muscles pushing against an inelastic bandage

22
Q

Compression is used to:

A

Control peripheral edema
Prevent deep vein thrombosis
Limit shaping after amputation

23
Q

Compression is not used for

A

Treating pts w ulcers caused by ARTERIAL insufficiency.

24
Q

Correct sequence for lymphatic flow

A

Veins to interstitial space to lymphatic capillaries to subclavian vein back to venous circulation

25
Q

What may result in edema?

A

Increased extravasation of fluid into interstitial space
Reduced venous flow
Reduced flow of lymph back to heart

26
Q

How do healthy lymphatic vessels and veins propel forward fluid flow?

A

By muscle contractions and back flow of fluid is prevented by valves within vessels

27
Q

Adverse consequences of edema include

A

Subcutaneous tissue fibrosis
Contractures and deformities
Increased risk of infection

28
Q

Compression reduces edema by:

A

Increasing hydrostatic pressure into circulation

29
Q

Compression garments used to minimize hypertrophic scarring should provide how much pressure?

A

20-30mm Hg or pressure

30
Q

High extensible bandages have

A

High resting pressure

31
Q

Low stretch bandages have

A

High working pressure

32
Q

Wen applying compression pumps u should

A

Cover open wounds
Measure and record blood pressure
Record limb circumference before and after

33
Q

What are stockings with less than 30mm Hg used for ?

A

Prevention of deep vein thrombosis formation in bed bound patients
