Modelling of Tracheal Gas Insufflation Effect

Popis výsledku v původním jazyce

The aim of this work was to find out the effect of tracheal gas insufflation during conventional and high frequency artificial lung ventilation upon arterial blood gases. The complicated lung structure does not allow an exact modelling according to the anatomical lung structure. Therefore, the respiration system is modelled as an axial symmetrical straight pipe with a growing radius. A base of the model is convention-diffusion equation, which is solved by numerical simulation. After that, the TGI catheter was added into the model for description of tracheal gas insufflation effect. The TGI catheter was modelled as an additional source of ventilation gas mixture. The outputs of the final model were compared not only with an animal experiment but also with another model derived from the electro-acoustic analogy. The acquired results are useful and directly applicable in TGI effect investigation and will contribute to the fast TGI introduction into the clinical practice.
