Q

exp laplace’s law

A

inc in pressure = pumping effect

tension = pressure x radius of chamber and is inversely prop to thickness of wall

Q

compare SPC to IPC

A

SPC - constant pressure; deprives BF to tissues since artery is compresses

IPC - intermittent; on off time or inflates and deflates; pumping effect = venous and lymph circulation

Q

discuss how IPC improves fluid balance and circulation

A

compressive force facilitates venous BF back to heart and lympahtic drainage to central areas = controls peripheral edema

Q

discuss how IPC prevents DVT

A

if immob - it can provide adequate BF to prevent accumulation of blood components

BUT DONT USE IF MAY DVT NA

Q

discuss how IPC heal venous ulcers

A

can heal grade 1 only - since better BF - better healing

Q

relate hydrostatic pressure in interstitial space and extravascular pressure

A

when hydrostatic psi inc in interstitial space = inc extravascular psi = edema

kaya compression can push back fluid in interstitial space back to BV or lymph veins

Q

when do we use static compression

A

when there is severe edema = since makapal na talaga need ng static to get through; di na ma ccompress arteries since anlaki tlaga ng edema

Q

discuss how IPC inc tissue temp

A

not rlly inc but more of insulator preventing release of heat

or depends on air being pumped if hot or cold

Q

how does IPC control scar formation

A

if heated air is used it can control scar formation - breaks down the collagen

Q

how does edema usually occur

A

either inc vascular hydrostatic or osmotic psi

venous or lymphatic insuff or obstruction

inc capillary permeability

inc plasma volume d/t NA and H2O retention

acute inflammation

airline travel

pregnancy

other medical conditions

18
Q

differentiate pitting vs non-pitting dema

A

pitting - better and more effective to treat with IPC; indentation appears when pressed

non-pitting - indentation does not form since more proteins assoc with formation of fluid; harder to drain

19
Q

how does edema occur d/t vascular hydrostatic or osmotic psi

A

either inc vascular hydrostatic or osmotic psi

high vascular hydrostatic psi = ppunta sa interstitial spaces

more proteins outside the BV = inc osmotic pressure that attracts fluid

20
Q

how does edema usually occur d/t venous or lymphatic insuff or obstruction

A

insuff or blocked vessels = fluid does not flow back properly = accumulation or edema

21
Q

how does edema usually occur d/t inc capillary permeability

A

easier for fluid to go outside

22
Q

how does edema usually occur d/t increased plasma volume due to Na+ and H2O retention

A

inc plasma = inc hydrostatic psi in veins = fluid goes to interstitial space

23
Q

how does edema usually occur d/t acute inflammation

A

could also result to edema

24
Q

how does edema usually occur d/t airline travel

A

prolonged seating in long flights and reduced air psi - may cause DVT or reason why more fluid goes outside

25
Q

how does edema usually occur d/t pregnancy

A

inc blood volume, alteration of smooth muscle tone or inc psi w/in veins

26
Q

how does edema usually occur d/t medical conditions

A

if medical conditions cant be fixed be compression - bcs if inc venous return and compromised yung heart or liver or kidney - more problems

27
Q

what is lymphedema

A

more of swelling cause by lymphatic fluid in interstitial space

28
Q

compare primary to secondary lymphedema

A

primary - congenital probs in lymphatic system; Milroy’s

secondary - other conditions that affects LS; cancer, arthritis, venous insuff, infections

29
Q

causes of lymphedema

A

hypoproteinemia and low serum albumin - attracts fluid to vessels so if low fluid tends to go out; osmotic psi

lymph obstruction

reduced physical activity

30
Q

exp appli of compression to post amputees

A

to prepare stump for prosthesis - prevent change of shape due to edema

31
Q

compare hypertrophic vs keloid scar

A

hypertrophic - raised ridge but does not extend beyond original wound

keloid - extends beyond

but both excessive scarring

32
Q

what type of scar is IPC effective

A

hypertrophic - dec height and vascularity and inc pliability

33
Q

contraindications of IPC

A

Heart failure or pulmonary edema

Recent or acute DVT, thrombophlebitis, or pulmonary embolism

Obstructed lymphatic or venous return

Severe peripheral arterial disease or ulcers d/t arterial insufficiency (ABI <0.8)

Acute local skin infection

Significant hypoproteinemia (protein levels <2 gm/dL)

Acute trauma or fracture

Arterial revascularization

34
Q

precautions of IPC

A

Impaired sensation or mentation

Uncontrolled hypertension

Cancer

Stroke or significant cerebrovascular insufficiency

Superficial peripheral nerves

35
Q

adverse effects if IPC

A

Aggravation of condition if excessive pressure is used

Aggravation of the underlying condition (ie heart, kidney or liver failure)

Too much pressure à impair arterial flow

36
Q

discuss resting vs working pressure in compression bandaging

A

resting - exerted by elastic bandage

working - produced by active muscle pushing against inelastic bandage

37
Q

compression garment for anti embolism

A

16-18 mmHg

38
Q

compression garment for modify scar after burns

A

10-50 mmHg

39
Q

compression garment control scar tissue formation

A

20-30 mmHg

40
Q

compression garment to control edema

A

30-40 mmHg

41
Q

how long should compression garments be worn

A

ALL DAY EVERYDAY and should last for about 6 months or longer
