摘要：
Airway impedance of a subject using a respiratory treatment device can be measured, in accordance with one or more embodiments. A conduit is configured to communicate a flow of inhaled gas and a flow of exhaled gas to and from an airway of the subject using the respiratory treatment device. A first valve is disposed within the conduit and configured to affect the flow of exhaled gas. One or more sensors are disposed within the conduit and are configured to provide a signal conveying information associated with one or more characteristics of gas exhaled by the subject while the flow of exhaled gas is affected or unaffected by the first valve. An airway impedance monitoring module can be executed by a processor to determine an impedance metric of the airway of the subject based on the information conveyed by the signal provided by the one or more sensors.
