Cardio & Lymphatic Systems and Lymphatic Facilitation Flashcards
Which vessel has higher elastic and contractile elements?
Arteries
What is vasoconstriction and vasodialation?
Vasoconstriction (increase sympathetic) - narrowing of the vessel
Vasodilation (Decreased sympathetic) - widening of the vessel
What is diffusion, osmosis, and filtration?
Diffusion - Passive transport based on concentration gradients
Osmosis - only water molecules move through osmotic pressure
Filtration - passive transport based on differences in pressure
What are the 4 starling forces causing fluid movement in the capillaries?
Capillary fluid pressure (CFP) - filtration
Interstitial fluid pressure (IFP) - reabsorbtion
Plasma oncotic pressure (POP) - reabsorbtion
Interstitial oncotic pressure (IOP) -filtration
How much movement of the fluid in our body does the lymphatic system aid in?
10%
What can bilateral edema be indicative of?
Heart problem
What’s the function of the lymphatic system?
Fluid return (open system) immunity
What are the components of the lymphatic system?
Lymph nodes (afferent-carry lymph into nodes, efferent-prevents backflow) Catchment (collects lymph from specific region, several nodes clustered together)
When does fluid become lymph?
When interstitial fluid enters lymphatic vessels
What are the 2 types of lymph capillaries?
Initial vessel - first capillary, more absorbant
Collection capillary - collects from multiple initial’s
What are the 2 lymphatic ducts?
Right - collects from upper right quadrant
Thoracic - everywhere else
Where does the fluid return to circulation?
Lymphatic Terminus
What are the types of edema?
Circulatory edema-avoid/extreme caution with lymphatic facilitation
Lymph edema- Primary: congenital or genetic defect, Secondary: when nodes or damaged
Traumatic edema- localized temporary swelling
What are the benefits of lymphatic facilitation?
Lowers secondary edema formation via protein removal
Limit hematoma organization to damage tissue
Lower pain via gate control and reduced pressure on nociceptors
What are some absolute contraindications for lymphatic?
Current infection Kidney dysfunction Active tuberculosis Thrombosis, ebolism, phlebitis Congestive heart failure
What are some relative contraindications for lymphatic facilitation?
Malignant disease
Monitor closely if hypotensive
Don’t work over: thyroid if hyperactive, sternum if asthmatic, or open wounds
Do you use emollient with lymphatic facilitation?
NO
How does the stationary circle stroke work?
“L” pattern: 1st go across line of lymph flow, then in line with lymph flow
What does the respiratory pump with lymphatic facilitation do?
Enhance lymph flow through deep structures by using breaths
Where is the external pressure placed during inhalation for the respiratory pump?
cisterna chili
What are the 3 stages of lymphatic facilitation?
- Start siphon - get things moving toward cachment (fill terminus, empty terminus)
- Clear the way - stationary strokes over catchment
- Promote edema uptake
What’s the treatment sequence of upper extremity?
- Fill terminus
- Empty terminus
- Axilla
- Upper arm
- Lower arm
- Axilla
- Empty Terminus
What’s the treatment sequence for the lower extremity?
- Fill terminus
- Empty terminus
3-7. Respiratory pump - Inguinal catchment
- upper leg (long stroke)
- popliteal
- lower leg
- popliteal
- upper leg
- inguinal
- respiratory pump
- empty terminus
