Air flow meters in ventilators are used to control the airflow, which is an important factor. Adults, for example, have different breathing volumes than younger persons, including children. As an alternative, temperature sensors have been used in ventilators to perform a simple air flow measurement, but they have a relatively large thermal mass. An IST flow sensor enables the possibility to have a better and more accurate adjustment through a higher sensor sensitivity, which results in better user experience while reducing the occurrence of drying out the patient’s nose, nose bleeding over time or even a lung injury from overventilation.  Considering a possible breathing cycle between 300 ms to 3 seconds, the faster response time on our SFS flow sensors down to a T63 of 5 ms, allows one to perform a detailed breathing profile while opening the possibility to detect very fine and subtle breathing disorders. Both sensors, the SFS and the FS2, are suitable to detect inhalation and exhalation with a single sensor, through a clear flow direction detection.
