This model was described by Dalla Man et al. in [3, 4]. Its equations are also the basis of the UVA/PADOVA Type 1 Diabetes Simulator (T1DMS).
Specifics and deviations
- For the digestion rate (kempt), different models are described in [3,4]. For simplicity, an average of maximum and minimum digestion rates was provisionally used instead of the complex calculation rules.
- Hepatic gluconeogenesis (, Eq. (4)) was limited to avoid singularity (, Eq. (5)) at high insulin concentrations.
- Subcutaneous insulin kinetics included in T1DMS  are not described in ; they were taken from , including the associated parameters
The default values of the parameters are taken from the “Normal Value” column in [3, Table 1] and describe the behavior of a healthy person.
The following scheme visualizes the state variables included in the model and the interactions between them:
It must be expressly pointed out that this is only a mathematical model which can at most describe the real processes in the human body approximately and in parts. Therefore, although the simulation results qualitatively resemble clinical curves, they must be interpreted with caution and are not suitable for deriving individual treatment strategies from them (see disclaimer). We do not assume any responsibility for the correctness of the results or damages of any kind resulting from the use of the simulator (see license).
