1. Parameter identification of the cardiovascular system model using computer

Given) Presure(mmHg) Volume(L)
sa 100 1 Cardiac Output
sv 2 3.5 = 5.6 L
pa 15 0.1
pv 5 0.4

Sol) Csa= Vsa/Psa= 0.01 L/mmHg
Csv= Vsv/Psv= 1.75 L/mmHg
Cpa= Vpa/Ppa= 0.0067 L/mmHg
Cpv= Vpv/Ppv= 0.08 L/mmHg

KR= Q/Psv= 2.80 L/min mmHg
KL= Q/Ppv= 1.120 L/min mmHg
RS= (1/Q)*(Psa-Psv)= 17.50 min mmHg/L
RP= (1/Q)*(Ppa-Ppv)= 1.785714286 min mmHg/L
V0= Vsa+Vsv+Vpa+Vpv= 5.00 L

2. Solve the model for the dependent variables using computer
-(dependent cariables : Vsa, Vsv, Vpa, Vpv; Psa, Psv, Ppa, Ppv; Q)

Given) KR= 2.80 KL= 1.12
RS= 17.50 RP= 1.79
Csa= 0.01 Cpa= 0.0067
Csv= 1.75 Cpv= 0.08
Vt= 5.00

Sol)
Tsv= Csv/KR= 0.625 min
Tpv= Cpv/KL= 0.071428571 min
Tsa= (Csa/KR)+(Csa*Rs)= 0.178571429 min
Tpa= (Cpa/KL)+(Cpa*Rp)= 0.017894657 min
Q= V/(Tsv+Tpv+Tsa+Tpa)= 5.59976472 L/min
Psv= Q/KR= 1.999915972 mmHg
Ppv= Q/KL= 4.999789929 mmHg
