peripheral vascular exam Flashcards
What do you inspect overall for in the peripheral vascular exam?
Colour
Hair distrobution
Skin thickness
Scars
Ulcerations
Variscosities
Edema
Muscle Wasting
Between Toes
-important to look for fungal infections and broken down skin between toes
Nail growth and appearance
What do you palpate for in the peripheral vascular exam?
Temperature-> over both legs with the backs of your hands simultaneously
Capillary refil time–> < 3 sec normal
Edema–> press and look for pitting/ non pitting edema.
-non pitting edema is likely from lymphedema
Remember, if they are bed ridded they will likely have edema on their cocxyx
Calf circumfrence–>5 cm below the tibial tuberosity symmetrically on both sides
>2 cm difference in the calf is abnormal
>1cm difference in the ankles is abnormal
Pulses–>
compare
1) Radial
2) Brachial
for rate, rhythm, symmetry and amplitude
compare
1) Abdominal
2) Femoral
3) Poplitieal
4) Dorsalis Pedis
5) Posterial Tibial
for symmetry and amplitude
Radial Femoral Delay->palpate the radial and femoral arteries looking for the femoral pulse to come before the radial pulse
if femoral pulse comes after radial pulse then think about something blocking off the aorta–> coarctation, aneurysm
What do you ascultate for in the peripheral vascular exam
1)Ausculatory blood pressure
2)Pulsus paradoxus–>
–>deflate the cuff to where you can hear first heart sounds on expiration only
->deflate the cuff to where you can hear the first heart sounds on inspiration and expiration
If there is more than a 10 mmHg difference then there is pulsus paradoxus
-This is common in cardiac tamponade and pericarditis ( inflammation of the heart and surrounding tissues)
3)ascultate the following arteries commenting on bruits
- brachial
- abdominal
- renal
- iliac
- femoral
1)special tests–>
Allens test–> patient clenches fist, holds above head, waiting for it to loose blood
- >lower hand with it still clenched, occluding the radial and ulnar arteries
- > release the ulnar artery and look for blood to return to hand
- >do again and release radial artery first
palm should redden within 5 seconds
if one slower than the other–> the slower of the arteries has an occlusion
if time delayed for both arteries–> proximal blockage
if there is no refil from ulnar then no connection between the deep and superficial palmar arches exists
2)Straight leg raise and refil test
- raise legs to 45-60 degrees for 30 seconds
- patient sits up and holds legs over the side of the bed
- natural pink colour should return to feet within 10 seconds
- if greater than 10 seconds then arterial insufficiency
- if dusky colour exists as well then venous insufficiency–> rubor on dependency test
3)incompetent saphenous vein test
- locate saphenous vein medial thigh down leg
- occlude proximally and distally 15-20cm apart
- tap proximally
- distal hand should not feel tap–> if it does-> incompetent saphenous vein
