Why Is ABI Effective in Detecting Vascular Stenosis? Investigation Based on Multibranch Hemodynamic Model
Figure 2
The electric analog circuit model of the entire cardiovascular system. Each component is comprised of a compliance variable , a resistance , and an inductance (1: aorta (a); 2: thoracic and abdominal aortae (l); 3/7: left/right femoral artery (afl/afr); 4/8: left/right popliteal artery (apl/apr); 5/9: left/right posterior tibial artery (atl/atr); 6/10: other left/right lower limb arteries (all/alr); 11/14: left/right brachial artery (abl/abr); 12/15: left/right radial artery (arl/arr); 13/16: left/right ulnar arteries (aul/aur); 17: carotid artery (ac); 18/19: left/right lower limb capillaries (alpl/alpr); 20/21: left/right upper limb capillaries (aupl/aupr); 22: brain (acp); 23/24: left/right lower limb veins (vll/vlr); 25/26: left/right upper limb veins (vul/vur); 27: jugular veins (vc); 28: system vena (ve); 29: Clv represents the compliance of the left ventricular). The effects of inertia for veins are not considered in this model.
