摘要
The oxygen therapy monitoring device (105) includes a vibrating chamber (403) included in a gas flow passage (201) configured to pass a gas flow from a source (102) to a breathing interface (106) for a person (101). Include. The oscillating chamber induces gas flow oscillations that vary as a function of gas flow rate. The measuring device (202) measures the vibration induced in the gas flow and determines the flow rate based on the measured vibration. [Selection] Figure 2
