Flashcards in Chapter 13 - Lymphatics Deck (11):
1

What drains into the R thoracic duct?

R head and neck
R arm
Heart
Lungs (except L upper lobe)

2

Where does the Left (major) duct drain into the venous system?

Junction of L subclavian and L internal jugular

3

What is the thoracic duct?

At what level does it turn around and go down?

The lymphatic duct that comes up from the thorax and drains into the left (major) lymphatic duct

C7

4

Describe the path of the thoracic duct

Cisterna chyli (L2) --> aortic hiatus (T12) --> neck

5

Extrinsic forces on the lymphatic flow

OMT
Exercise
Contraction of muscles
Pulsation of adjacent arteries
Respiratory movement (negative pressure)

6

Intrinsic forces on lymphatic flow

Smooth muscle contraction (SNS)
Interstitial fluid pressure

7

Factors that cause interstitial pressure to increase above 0 mmHg such that the lymphatic capillaries collapse (4)

All 4 result in what?

- Systemic HTN
- Cirrhosis
- Hypoalbuminemia (starvation, kidney damage)
- Toxins (rattlesnake poison)

Increased fluid flow into the interstitium from the blood capillaries

8

Thoracic pump - function

Increase rib cage motion
Mobilize lymphatic fluid

9

Pedal pump - function

Encourage lymphatic movement, especially in CHILD

10

Basic treatment protocol for lymphatics (4)

1. Thoracic inlet
2. Rib raising or paraspinal inhibition
3. Redome the thoracoabdominal diaphragm
4. Lymphatic pump techniques

11

Relative contraindications to lymphatic treatment (4)

Osseous fractures
Bacterial infections w/ FEVER
Abscess or localized infection
Carcinomas (especially late)
