This thesis, a collaboration between Getinge and KTH, aims to develop an advanced CFD model to investigate and optimize a High Frequency Oscillation Ventilator (HFOV). The HFOV delivers very small tidal volumes at frequencies of 5–20 Hz, creating time-varying flow in the complex, compliant geometry of the lung. Current evaluation methods, mainly based on tidal volume, are too limited to capture gas exchange dynamics. The project will model CO2 elimination for varying flow/pressure profiles, patient lung characteristics, and ventilator breathing system (VBS) designs. Work includes literature review, lung geometry modeling, ventilator flow/pressure data analysis, VBS modeling, and validation against Getinge's lab setup. Sensitivity analyses will support performance optimization. The student will gain advanced skills in CFD, biomedical engineering, and data-driven modeling, experience valuable for research careers and roles in medical technology innovation.

Background 

High frequency oscillation (HFO) is a special mode of ventilation where very small tidal volumes are delivered at breathing frequencies far beyond what a breathing person can achieve (in the range of 5-20Hz).

The HFO mode is characterized by a time-varying flow with a wide frequency spectrum that is applied to a complex branching geometry (patient's lung). The lung is compliant where the pressure affects the models' geometrical boundaries.

Today, much of the evaluation of performance is made using the tidal volume (integrated flow pattern over an inspiration), which most likely is too blunt of an instrument to optimize the performance of the HFO.

There is a challenge related to the determination and evaluation of the performance and efficacy of this therapeutic modality and there is a need to investigate how the current state-of-the-art in CFD modeling would be able to describe and optimize this ventilation mode.
