Blood Vessels Flashcards
pulse amplitude
force - created 0 (absent) to 4 (bounding)
Seven locations for palpation of arterial pulses
• Carotid: below mandible; best for evaluating heart function
o Can have patient turn head to side begin examined to relax sternocleidomastoid muscle
• Brachial: medial side of inner elbow
• Radial: radial side of wrist
• Femoral: inguinal area
• Popliteal: behind knee
• Dorsalis pedis: top of foot b/t 1st and 2nd metatarsals
• Posterior tibial: inner ankle inferior and posterior to ankle bone
bruit
murmur or unexpected sound; use bell since low-pitched
- Locations: carotid, subclavian, abdominal aorta, renal, iliac, and femoral arteries
- during carotid, ask patient to hold breath to distinguish breath and pulse sounds
audible bruit lt of umbilicus
abdominal aortic aneurysm
claudication
pain that results from muscle ischemia (loss of blood flow); can indicate peripheral artery disease; subsides with stop in activity
ways to assess arterial insufficiency
o Elevation of limb (suspected slight pallor) followed by lowering below heart (expected blood return within seconds)
o Capillary refill time: occluding blood flow by putting pressure on capillary beds in fingernail or toenail
- normal - less than 2 seconds
jugular venous pressure
vertical distance of the meniscus above the level of the heart (cm of water)
o Value less than 9 cm H2O = expected
jugular pulse
can only be visualized; not palpated
taking JVP
• Need two pocket rulers, patient lies supine, tangential light over rt side of neck
ways to confirm JVP
hepatojugular reflux (JVP observed in neck elevated with abdominal pressure) and venous engorgement of hands at levels above heart
signs of venous obstruction
pain with
o Swelling and tenderness over muscles
o Engorgement of superficial veins
o Erythema and / or cyanosis
NOTE: can only confirm thrombosis (clot) with ultrasound!!
signs of venous insufficiency
thrombosis, varicose veins, edema
Homan Sign
flex patient’s knee slightly with 1 hand and dorsiflex the foot = pain is a positive sign of venous thrombosis
pitting edema
sign of venous obstruction and insufficiency
NOTE: cannot be used to determine!!
o Severity measured by grading 1+ (slight pitting, disappears rapidly) to 4+ (very deep; lasts 2-5 minutes)
pulses in infants
Infants: brachial, radial, and femoral pulses easily palpated
• Bounding pulse = patent ductus ateriosus
• Difference in amplitude b/t upper extremity pulses or b/t femoral and radial or lack of femoral = coarctation (narrowing) of aorta
• Capillary refill time rapid – expect less than 1 second
