During the COVID-19 pandemic, up to twice as many fires and explosions related to the occurrence of dangerous oxygen concentrations in hospitals were recorded compared to non-pandemic times. This was probably due to the lack of preparedness of hospitals for the sharp increase in the use of ventilators during oxygen therapy in seriously ill patients with COVID-19. The pandemic thus showed that it is necessary to consider departments working with medical oxygen as potentially dangerous and to introduce systemic measures that can eliminate these risks threatening human lives. A possible solution to prevent fires related to the occurrence of dangerous oxygen concentrations is the use of a smart measuring system designed by us, which can accurately and promptly detect increased oxygen concentrations. The wireless device is based on Internet of Things technology and meets the requirements for long-term monitoring within the hospital environment. The oxygen concentration is measured at regular intervals and the data is wirelessly transmitted to a database storage. If the set oxygen concentration value is exceeded, hospital staff is notified via SMS and email.

Keywords: COVID-19, Measurement system, IoT, Oxygen Concentration Measurement, ICU, Gas Detection, IQRF.
