Equations and Data for O2 and CO2 solubility in water, normal saline, human & Ox plasma. This model uses individual fit data to express the O2 and CO2 solubility in various biological solutions. Please refer to the Notes tab for further details on the model and files.
Calculates the oxygen and carbon dioxide solubility across a physiolgical range of temperatures through various media (water, 155 mM normal saline, human & Ox plasma. O2 = AO2 *exp(-O2k1 *t) + BO2 *exp(-O2k2 *t). CO2= ACO2*exp(-CO2k1*t) + BCO2*exp(-CO2k2*t).
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.
