Distributed model for the O2-CO2 transport and exchange in the arterial portion of the vasculature.

Description

  Alternate model name: RBC_plasma_exch_O2_CO2_

  Distributed model for the O2-CO2 transport and exchange in the arterial
  portion of the vasculature.  The input partial pressures of O2 and CO2 in
  plasma and RBCs and plasma pH are specified by the external functions, 
  pO2plin, pO2rbcin, pCO2plin, pCO2rbcin and pHplin. The instantaneous 
  equilibrium bindings of O2 and CO2 with hemoglobin are characterized by 
  the invertible Hill-type equations developed by Dash and Bassingthwaighte
  (Ann Biomed Eng 32:1676-1693, 2004.)  Transport and exchange between the 
  plasma and the RBCs exists along the length of the vessel with none 
  thorugh the vessel wall into the surrounding interstitial and cellular 
  region.

  This code is strongly based on the blood-tissue exchange (BTEX) model code
  developed by Ranjan Dash, Assistant Professor, Compuational Bioengineering 
  Group, Medical College of Wisconsin.  Modifications to this code were made
  by Gary Raymond and Brian Carlson, National Simulations Resource, 
  Department of Bioengineering, University of Washington.

Equations

The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual. Additional documentation for MML can be found by using the search option at the Physiome home page.
