Flagship 1: Model-based diagnostics & therapeutics in pulmonary medicine


Our Flagship is creating a data-driven and validated ‘virtual lung’, as an enabling technology for patient-specific treatment in a range of areas. The virtual lung spans from the nasal and oral airways to the deepest smallest parts of the lung, connects to the circulatory system, exchanges respiratory gases, and interacts with models for central and peripheral respiratory control. A lean version of the model provides rapid analysis of breath-by-breath data at the bedside, and higher fidelity versions of the model provide deep analysis of patient response to treatment. Inclusion of imaging and pulmonary function data from hundreds of normal healthy subjects means that the model appropriately represents structure-function relationships over the full adult lifespan. The overall goal is to provide a comprehensive tool that can be used to predictively test interventional approaches and therapies, both well in advance and at the bedside, to develop and optimise new and current treatments for the individual, as well as to identify and stratify patients into risk groups and groups in need of more targeted, personalised therapies.
