Symbols | Variables/parameters | Symbols | Variables/parameters |
|---|---|---|---|
Pla (Pra) | Left (Right) atrial pressure | Rpar(Rpc) | Pulmonary arteriole (capillary) resistance |
Plv (Prv) | Left (Right) ventricular pressure | Rvp | Pulmonary venous resistance |
Pvs | Systemic venous pressure | Ras | Systemic peripheral arterial resistance |
Ppam | Main pulmonary artery pressure | Cvs(Cvp) | Systemic (Pulmonary) venous compliance |
Ppas | Small pulmonary artery pressure | Cpam(Cpas) | Main (Small) pulmonary artery compliance |
Pvp | Pulmonary venous pressure | LTALin, LTALala, LTALan | The three inductances model the inertia in the grafts. They depend by the blood density, the graft radius and the graft length |
Pt | Mean intrathoracic pressure | Lpam(Lpas) | Inertance of main (small) pulmonary artery |
Qlia(Qria) | Left (Right) atrial input flow | Cvs(Cvp) | Systemic (Pulmonary) venous compliance |
Qli(Qri) | Left (Right)ventricular input flow | CTALad(CTALap) | Compliance of the TAL inlet (outlet) chamber |
Qlo(Qro) | Left (Right) ventricular output flow | CTALin | Inlet graft compliance to the TAL |
Rli(Rri) | Left (Right) input valve resistance | RTALin | Inlet graft resistance to the TAL |
Rlo(Rro) | Left (Right) output valve resistance | RTALpab (RTALala) | Resistance used to divide the flow between pulmonary artery (RTALpab) and left atrium (RTALala) |
Rvs | Systemic venous resistance | RTALad(RTALap) | Flow dependent inlet (outlet) resistance |
Rpam(Rpas) | Main (Small) pulmonary artery resistance | RTALan | Outlet graft resistance to the pulmonary artery |
