Many smartphone apps work in conjunction with inhalation or measurement devices. A position paper presented in November 2019 by the German Respiratory League, the German Society for Pneumology and Respiratory Medicine and the Association of Pneumological Clinics refers to these as eDevices. These include smart add-ons – hardware that can be connected to an existing inhalation device – on the one hand, and smart devices on the other. These are integrated solutions in which the electronic components are built into the inhalation device. In the app, the collected data and measured values can be made visible to the patient and made available to the attending physician. Furthermore, there is supplementary hardware for the mobile application, which primarily serves to monitor progress and activity. These include peak-flow meters, spirometers, FeNO meters, and activity and sleep trackers. The data can be transmitted to the smartphone via Bluetooth.
With Vivatmo me, Bosch has developed the first FeNO meter for the home. "Users simply exhale into the hand-held device as steadily as possible for just a few seconds. The exhaled breath is analyzed with the device measuring the so-called FeNO value, a measurement of fractional exhaled nitric oxide (NO). This is a marker that indicates the degree of airway inflammation due to an allergic reaction," explains Dr. Stefan Gebauer of Bosch Healthcare Solutions GmbH in an interview. Vivatmo me can be connected to the associated smartphone app, a digital asthma diary in which information on medication, personal condition, additional values from peak-flow meters, for example, or asthma attacks can be entered. "It allows the user to better navigate his disease and detect correlations – and spot allergy triggers that can cause an inflammatory response.," Gebauer says. Based on the final report, the therapy can be adjusted with the doctor.
