deep veins carry __ % of blood volume 85%
from the adductor canal to the CFV Femoral Vein
paired veins that lie along the intermuscular septum posterior tibial veins
peripheral resistance in cap beds may __ in response to heat, inflammation, and infection Decrease
what is the distal venous pressure when lying down 10mmHg
paired veins that lie close to the medial aspect of the fibula peroneal veins
cleopatra's eye GSV
T/F a high to low pressure gradient must exist for perfusion to occur True
paired veins that lie above the interosseous membrane ATVs
what is the distal venous pressure when standing and can cause what if standing to long 80mmHg, decrease in CO/Hypotension
most common perforator in the calf Cocketts
unilateral continuous venous flow is suggestive of ilsilateral thrombosis in the Iliac or extrinsic compression
during inhalation the venous outflow is reduce- due to increase in intra-abd pressure collapsing the IVC
Name the 3 pump sysems foot pump, calf pump, thigh pump
varicose veins, claudication, stasis dermatitis, stasis ulceration are symptoms of DVT or Insufficiency? Venous Insufficiency
pulsatile flow in the CFV- bilaterally suggest CHF
bilateral continuous waveform suggest PE, supine position, shallow breathing, or IVC obstruction
T/F no muscle contraction, no pump action True
T/F dysfunctional valves are Primary insufficiency False: Primary- congenital absence of valves. Secondary- dysfunctional, damaged valves
