1

Effects of External Compression

1. Improves venous and lymphatic circulation
2. Limits the shape and size of tissue
3. increases tissue temperature

2

Indications for Compression

1. Edema Control
2. Prevention of DVT
3. Venous Stasis Ulcers

3

How does compression reduce edema?

Increases extravascular hydrostatic pressure and promotes circulation

4

Contraindications

1. Heart Failure
2. Pulmonary edema
3. Recent or acute DVT/thrombophlebitis/ pulmonary embolism
4. Obstructed lymphatic or venous return
5. Severe peripheral artery disease
6. Acute local skin infection
7. Hypoproteinemia (

5

Precautions

1. Impaired sensation/mentation
2. Uncontrolled hypertension
3. Cancer
4. Stroke or cerebrovascular insufficiency
5. Superficial peripheral nerves

6

Adverse Effects

1. Aggravating a conditions that causes edema
2. Impairing circulation with excessive pressure

7

Application Techniques

1. Compression bandages
2. Compression garments
3. Velcro-closure devices
4. Intermittent pneumatic pumps

8

Parameters for intermittent pneumatic pumps

1. Inflation Time
2. Inflation Pressure
3. Treatment time

9

Inflation Time for pneumatic pumps

DVT Prevention -- 80-100 seconds with a deflation time of 25-50 seconds
Residual limb reduction -- 40-60 seconds with deflation time of 10-15 seconds
Usually inflation to deflation ratio is 3:1

10

Inflation Pressure for pneumatic pumps

Generally between 30 and 80 mmHg
For upper extremities -- 30-60 mmHg
For lower extremities -- 40-80 mmHg

11

Treatment Time for pneumatic Pumps

1-4 hours per treatment 3 to 4 times per day

12

Types of compression bandages

1. Short stretch
2. Long Stretch
3. Multilayer

13

Long-stretch Bandage

Elastic bandage that extends by 100-200% and provides high resting pressure

14

Short-stretch bandage

Low elasticity bandage with 30-90% extension that provides low resting pressure but a high working pressure during muscle activity
Most useful during exercise

15

Multilayered Bandage

Use of both elastic and inelastic layers to apply moderate to high resting pressure through multiple layers of bandages

16

How does compression prevent DVT?

Increases circulation, DVT is caused by reduced circulation

17

How does compression improve venous stasis ulcers?

Improves circulation
Improves rate of healing through multilayered compression and high pressure
