Q

Your patient comes in with what looks like bilateral swollen legs. You are able to pinch the skin on the top of the foot. What is your hypothesis?

A

Lipedema: Abnormal accumulation of adipose tissue in the LE, can be mistaken for lymphedema, dorsum of the feet are spared

Q

Your patient is able to walk around in their bandage…what type of compression bandage would you use?

A

Inelastic (short stretch) bandage b/c pressure increases when the patient moves. This bandage doesn’t apply compression, doesn’t expand when the muscle contracts and is able to conform to the extremity. At rest pressure is 28 mmHg ( medium compression)

Q

What type of compression is 40-<60 mmHg

A

Strong Compression

13
Q

This type of compression provides grades compression from the ankle to below the knee.

A

Compression Stocking

14
Q

Define the classes of compression stockings

A

Class 1: 14-19 mmHg
Class 2: 19-24 mmHg
Class 3: 25-35 mmHg
Class 4: 40-50 mmHg

15
Q

Provide examples of single layer elastic compression bandages

A

-Ace Wrap
-Coban
(Provide mild compression)

16
Q

These bandages are 2-4 layers and provide moderate to high compression

A

Multilateral elastic compression bandages

17
Q

With this type of bandage pressure will decrease with movement, and example is the Unna Boot. Certain amount of pressure is applied to the extremity (ideal is 35-45 mmHg)

A

Long Stretch Compression Bandages

18
Q

What is the purpose of using compression devices for edema reduction?

A

-Improves healing environment
-Reduces neuromuscular inhibition
-Improves ROM
-Decreases pain
Also, helps prevents DVT by increasing venous flow which prevents clots

19
Q

This type of compression device inflates as a unit

A

Circumferntial Unit

20
Q

If you want to inflate the compression unit and have it remain inflated…what would you call this

A

Constant Unit

21
Q

Name at least 8 contraindications for use of a compression device

A
  1. ) Acute or unhealed fracture
  2. ) Uncontrolled Hypertension
  3. ) Compartment Syndrome
  4. ) Current PVD
  5. ) Arteriosclerosis
  6. ) Edema secondary to CHF
  7. ) Ischemic vascular disease
  8. ) Pulmonary edema
  9. ) Gangrene
  10. ) Dermatitis
  11. ) DVT
  12. Thrombophlebitits
22
Q

When the unit milks from distal to proximal, chambers inflate individually

A

Sequential Unit

23
Q

Air (pneumatic) or chilled water (hydraulic) are what type of unit?

A

Media Unit

24
Q

Name the physiological effects of compression devices

A
  • Mechanical pressure reduces edema
  • Forces venous fluids proximally
  • Decrease capillary filtration pressure, limiting formation of edema
  • Increased lymphatic uptake
  • Improved absorption and removal of solid wastes
  • Increase ROM
  • Decrease Pain
25
Q

What are some things that can be done with compression therapy?

A
  • Elevation of limb (gravity assists in venous and lymphatic return
  • Electrical Stimulation: Motor level stimulation provides muscle pump
26
Q

What step is out of order for Termination of the Treatment?

  1. ) Reduce the ON time or select the DRAIN mode to remove the air or fluid from the appliance
  2. ) Allow the appliance to deflate
  3. ) Remove body part
  4. ) Apply a compression wrap and any appropriate supportive device
  5. ) Re-measure circumference of extremity and determine amount of edema reduction
  6. ) Encourage patient to keep the limb elevated whenever possible between treatments
A

Step #5 is wrong, it should be step #4

  1. ) Reduce the ON time or select the DRAIN mode to remove the air or fluid from the appliance
  2. ) Allow the appliance to deflate
  3. ) Remove body part
  4. ) Re-measure circumference of extremity and determine amount of edema reduction
  5. ) Apply a compression wrap and any appropriate supportive device
  6. ) Encourage patient to keep the limb elevated whenever possible between treatments
27
Q

What are the steps for initiation of compression therapy?

A
  1. ) Set TEMP between 50-55 F
  2. ) Select the MAX PRESSURE for tx.
    - 30-60 mm Hg for UE and 60-80 for LE
  3. ) Select the ON-OFF times
    - 3:1 duty cycle is often used
  4. ) Select TREATMENT TIME
    - Post-traumatic edema: 20-30 minutes
    - Lymphedema: Several hours
28
Q

What things should you be instructing the patient on during/before the compression device starts?

A
  • Inform pt about sensations to be expected
  • Instruct pt to perform ROM exercises during the off cycle
  • If sessions are longer then 60 minutes you must stop session and inspect extremity for proper capillary refill and sensation or the presence of unusual marking or unexpected pitting edema
29
Q

Maintenance of the machine after each treatment includes what….

A
  • Check for leaks/tears, if found repair with an approved patch kit or return to manufacture
  • Clean the appliance using an approved cleaner
  • If machine washable, turn them inside out and close them
30
Q

Quarterly maintenance includes…

A

-Check air/water hoses, clean external unit, check plugs, cables and cords for frays etc

31
Q

Annually or as required maintenance includles

A

A qualified technician should perform an inspection and calibration and perform any needed maintenance

32
Q

Application of compression therapy includes

A
  • Distal to Proximal
  • Wrap medial to lateral with an initial figure 8
  • Decrease tension moving proximally
  • Avoid circumferential and spiral wrapping
  • Assess capillary refill post application
