COVID-19 is causing respiratory problems for a multitude of patients and is directly affecting hospitals, especially Intensive Care Units (ICU), where in many cases there are not enough mechanical ventilators to help patients to breathe. DEKRA laboratories are working on various projects of ventilator system manufactures. As these medical devices need to be assessed to assure its safety. In addition to electromagnetic compatibility (EMC) and electrical safety tests, functional tests of the ventilator’s performance are essential. Hence, gas flow analyzers and test lungs are used to test the essential performance of any ventilator – both in manufacturing and during preventive maintenance in hospitals.

Temperature influence in flow and volume measurement
In mechanical ventilators, the inspiratory and expiratory volumes (Vti, Vte) and minute volumes (Vi and Ve) must be precisely checked using gas flow analyzers or
