Q

What is the composition of lymph?

A

The composition of lymph is fairly similar to that of blood plasma, with the majority of the volume (around 95%) comprised of water. The remaining 5% is composed of proteins, lipids, carbohydrates (mainly glucose), various ions and some cells (mainly lymphocytes).

  8. Osteomyelitis
  9. DVT
  10. Compartment syndrome
  11. If the patient is using anticoagulants (To prevent blood clots)
  12. Uncontrolled high blood pressure
  13. Unstable cardiac conditions/angina
36
Q

The pedal pump technique uses what mechanism?

Explain how this mechanism works?

A

Calf pump mechanism

Dorsiflexion of the foot, the lymphatic vessels are compressed between the soleus and gastrocnemius muscles.

Encouraging the flow of lymph towards the heart.

37
Q

Whilst performing the pedal pump technique, the recoil of the foot creates what type of pressure?

A

Negative pressure, assisting with the movement of lymph towards the heart.

38
Q

Name 5 contraindications to the pedal pump

A
  1. DVT
  2. Compartment syndrome
  3. Ankle Sprain
  4. Achillies strain
  5. Recent fracture/Inversion sprain
39
Q
  1. Knee drainage technique, collects lymph from? (3)
  2. How does this technique help promote the flow of lymph?
  3. Lymph is drained into what nodes?
A
  1. Lower extremity

Knee, calf, foot, ankle

  1. Gravity

Movement of joints

Removes fascial restrictions

  1. Deep and superfical popliteal nodes
40
Q

Name the boundaries of the popliteal fossa?

Contents? Lateal to medial

A

Tibial nerve, popliteal artery, vein

41
Q
  1. Explain the mechanism behind thigh twists.
  2. Thigh twists help to promote the movement of lymph from the popliteal nodes towards?
A

The twisting motion of the thigh, creates a localised suction effect.

What contraindications could prevent the application of the inguinal pump.

A

Knee, hip pathology

44
Q

What is the mechanism behind the inguinal pump?

A

Circumduction of the hip with overpressure over the roof of the femoral triangle helps to promote the flow of lymph towards the heart.

Gravity/compression

45
Q

The deep and superficial lymphatic nodes drain into?

A

Superficial and deep illiac nodes

Where is it located?

Where does it drain lymph from?

47
Q

The cysterna chyli is an extension of what duct?

What is the mechanism behind cysterna chyli

A

Traction with left rotation over the hip influences the pumping motion of the cysterna chyli between the vertebrae and the crus of the diaphragm.

49
Q
A
50
Q

The cysterna chyi travels through which aperture of the diaphragm?

A

Aortic hiatus

51
Q

Sibsons facia is also known as?

52
Q

What are the boundaries of sibons fascia

A

inner border of the first rib and costal cartilage anteriorly, C7 transverse process posteriorly and to the mediastinal pleura medially.

53
Q

What is the function of sibsons fascia?

A

provide rigidity to the thoracic inlet that prevents distortion due to changes in intrathoracic pressure during respiration

54
Q

Adhesive capsilitis

Rotator cuff strain

Ligament sprain

Recent history of A/C or S/C joint sprain/dislocation

56

A

Metastaric cancer

Costocondritis

Angina

Heart condition

Recent rib fracture

Osteoporosis etc

58
Q

Explain the mechanism behind the thoraic pump technique

A

Inspiration released created a sudden negative intrathoraic pressure, creating a suction effect opening the thoracic ducts

59
Q

What is lymph?

What is its composition?

A

Derived from interstitial fluid

Similar composition to plasma but contains a high concentration of protein, lipids, water, lymphocytes

60
Q

What fluid acts as the lympahtic system of the brain

A

CSF

61
Q

How is lymph formed?

A

Plasma is filtered by blood capillaries to form interstitial fluid

Received by blind ended capillaries which enters into the lymphatic vessels

62
Q

What is the function of lymph

A

Plays a key role in the bodys immune defense

Helps to drain interstitial fluid

Helps to drain fluid from the periphery and areas of inflammation
