Transcript of A Computational Model of Cardiopulmonary Resuscitation

A Computational Model of Cardiopulmonary Resuscitation Problem - CPR is not effective Survival rate for reported cardiac arrests: 1% - 30% (American Heart Association, 2007)
With defibrillation

Solution - Computational Modeling Blood Volume

Blood Pressure

Blood Flow

Blood viscosity

Blood inertia

Vessel wall elasticity

Valves

Collapse Electrons

Voltage

Current

Resistance - R

Inductance - L

Capacitance - C

Diodes

Variable L,C, and R Put them together! Math Kick In! Cook the equations in Matlab %% Volume-defined pressure
p600(n+1) = V60(n+1)/C60+p_e;
p700(n+1) = V70(n+1)/C70+p_e;
p800(n+1) = V80(n+1)/C80+p_e;

p850(n+1) = (QV85(n+1)*t_inc+Ptr850(n)*arrayC85(n+1))/(2*arrayC85(n+1)-arrayC85(n))+p_e;

p1100(n+1) = V110(n+1)/C110+(p_e+1/5*p1000(n+1)); % 7/2 EAS p_e added as requested by AN
p1200(n+1) = V120(n+1)/C120+p_e;

p1350(n+1) = V135(n+1)/C135;
p1400(n+1) = V140(n+1)/C140; % 7/2 EAS p_e removed as requested by AN
% p1500(n+1) = p_e+V150(n+1)/C150;
p1500(n+1) = (QV150(n+1)*t_inc+Ptr1500(n)*arrayC150(n+1))/(2*arrayC150(n+1)-arrayC150(n))+p_e; Animal Experiments - not accurate Human Experiments - unethical Results - Textbook Realistic & Clinically Sound Heng 'Marshall' Yang 24Marshall@gmail.com Future Reference Blood distribution in the body American Heart Association, I.

Greater Cardiac output

Maintain vessel diameter

Time dependent Find a better CPR technique
Find the Difference! Round one Round two In CPR Major thoracic veins collapse

Occlude blood flow Certain signals open the veins People Supervisor: Abraham Noordergraaf
