A respiratory therapy (RT) system may be configured for acoustic operations. Such a system may include one or more acoustic generators to produce an inaudible acoustic signal that may be implemented for different uses. The acoustic generator(s), such as when coupled to a patient interface or air circuit of a respiratory therapy device, may provide inaudible acoustic signals whereby data concerning respiratory therapy may be collected at low cost, reducing cost of care in providing respiratory therapy. For example, the acoustic generator(s) may be configured to generate an acoustic signal indicative of one or more parameters, such as a flow rate or a pressure of the flow of air, or a type of or useable life of a component (e.g. patient interface). The system may have an acoustic receiver that may detect one or more acoustic signals from the acoustic generator, the RT system, the patient or the environment.
A system for treating a respiratory disorder in a patient, the system comprising a patient interface, a pressure generator configured to generate, for treating the respiratory disorder, a downstream air flow having a flow rate and a pressure, and an air flow path in fluid communication with an air outlet of the pressure generator and an air inlet of the patient interface, the system comprising a sensor for measuring a gas characteristic of a flow of breathable gas being directed to a patient interface for treatment of a respiratory disorder, said sensor comprising:
A method for measuring a gas flow rate of a flow of breathable gas directed to a patient interface in a system for treating a respiratory disorder in a patient, the system comprising the patient interface, a pressure generator configured to generate, for treating the respiratory disorder, a downstream air flow having a flow rate and a pressure, and an air flow path in fluid communication with an air outlet of the pressure generator and an air inlet of the patient interface,
