Blood Flow Restriction (wk6) Flashcards
What is a training method which involves applying tourniquet system to the most proximal region of the UE and/or LE?
Blood Flow restriction therapy
Tourniquet cuff partially restricts what blood flow and fully restricts what blood flow?
Partially - arterial inflow
Full - venous outflow
Compression of arteries results in what within the muscle tissue?
results in inadequate oxygen supply (hypoxia)
Compression of venous outflow results in what within the limb?
results in blood pooling in the capillaries of the limb
T/F BFR can be applied during both voluntary resistance exercise, aerobic exercise, and passively without exercise
True
What type of resistance exercise performed with BFR?
Low load
What is the goal of BFR?
mimic the effects of high intensity exercise by recreating a hypoxic environment using a cuff while performing low intensity exercises
T/F High load resistance exercise is equal to BFR resistance exercise.
False, high load resistance exercise is superior to BFR-resistance exercise, BFR is more effective than low load resistance exercise alone and can be used when high load resistance exercise is not appropriate
BFR-AE occurs with what type of exercise? At what intensity?
- occurs with walking or cycling
2. 45% heart rate reserve or 40% VO2 max
P-BFR (passive) provides benefits to who?
could provide benefits for patients following surgeries, prescribed bed rest, or in intensive care unit if not contraindicated
Safety concerns in regard to BFR are around what 2 things?
- formation of venous thromboembolism (deep vein thrombosis and pulmonary embolism)
- Muscle damage
Contraindications of BFR (10):
- Venous thromboembolism
- Peripheral vascular compromise
- Sickle cell anemia
- Extremity infection
- Lymphadenectomy
- Cancer or tumor
- Extremity with dialysis access (don’t do BP there either)
- Increased intracranial pressure
- Vascular grafts
- Medications known to increase clotting risk
