摘要：
We provide a respiratory therapy system comprising:
a flow generator;
a humidifier;
a respiratory conduit
a patient interface coupled to the respiratory conduit to deliver a gases flow to a patient;
a sensor configured to determine pressure or flow of the gases flow;
a controller configured to control the flow generator to generate the gases flow; and the controller configured to:
a) retrieve at least one first signal associated with or indicative of a gases flow and/or pressure in the respiratory conduit;
b) determine a measure of at least one first parameter associated with gases flow perturbations and/or pressure perturbations for at least one portion of the retrieved at least one first signal; and
c) determine the presence of liquid in the respiratory conduit based at least in part on the measure(s) of the at least one first parameter meeting a first threshold.
The system can be used to reduce or alleviate condensation in a respiratory gas deliver conduit.
