Abstract
Systems and methods for delivering therapy and/or medicament to a subject use one or more sensors to generate signals that represent characteristics of ultrasonic energy emitted during the use of respiratory medicament delivery devices. Parameters based on these signals indicate energy amplitude in one or more frequency ranges. Such parameters can be used to characterize the emitted ultrasonic energy and control and/or monitor device operation and/or patient adherence.
Claims9
A system configured to provide respiratory therapy to a subject, the system comprising:
- a respiratory therapy delivery device configured to deliver breathable gas to an airway of a subject during inhalation;
- an ultrasonic sensor for detecting ultrasonic energy, the ultrasonic sensor configured to generate output signals conveying information related to ultrasonic energy emitted by the airway of the subject;
- and
- one or more processors configured to execute computer program modules, the computer program modules comprising:
- a parameter determination module configured to determine, based on the generated output signals, a first parameter that indicates energy amplitude of the emitted ultrasonic energy;
- and
- a characterization module configured to determine a characterization of the emitted ultrasonic energy, wherein the characterization is based on the first parameter, and wherein the characterization includes one or more respiratory parameters of the subject.
A method of providing respiratory therapy to a subject, the method comprising;
- delivering, by a respiratory therapy delivery device, breathable gas to an airway of a subject during inhalation;
- generating, by an ultrasonic sensor, output signals representing one or more characteristics of the ultrasonic energy emitted by the airway of the subject;
- determining a first parameter that indicates energy amplitude of the emitted ultrasonic energy based on the generated output signals;
- and
- determining a characterization of the emitted ultrasonic energy, wherein the characterization is based on the first parameter, and wherein determining the characterization includes determining one or more respiratory parameters of the subject.
