Patients experiencing a severe course of COVID-19 often require ventilation, some of them with a non-invasive method, others in an intensive care unit. In either case, the patient's lung function and respiratory parameters have to be monitored. Patients and also the health-care staff should be provided with the best possible protection from a viral infection. An intelligent viral filter for use with both non-invasive and invasive ventilation is aimed at enabling this high level of protection. In the project Filter4Flow, Fraunhofer scientists are collaborating with the companies Aircontrols, ELK and MT-Consult to develop such a smart viral filter – a novel combination of fast sensor elements for measuring the flow rate, pressure and inhaled gas and a viral filter. The signals are digitized and transmitted quickly and wirelessly to a ventilation or patient monitoring system (e.g. an app). The intelligent viral filter allows precise, reliable and at the same time cost-effective breath monitoring in numerous patients, while also providing a filter function that protects both patients and staff from infection. This can help prevent the dreaded shortage of ventilation resources.
