Virtual Lung

Mechanical ventilation for patients suffering from lung diseases can lead to severe complications. Although it is known that the unnatural loading of diseased lungs during ventilation is responsible for an overstraining of the tissue, the specific processes cannot be captured even with the most modern imaging techniques. Therefore, computer simulations can substantially contribute to gaining new insights into these so called ventilation-induced lung injuries.

At the Institute for Computational Mechanics (TUM), scientists have developed a ‘virtual lung’, enabling the detailed investigation of important phenomena such as air flow from the windpipe to the smallest airways and the resulting local straining of the tissue. Information obtained from these very complex simulations at the GCS can help physicians predict the effect of different interventions and develop improved patient-specific treatments in the future.
