Systems and methods for providing respiratory therapy overcome various effects of transport delay within tubing of a respiratory therapy device by virtue of estimating and compensating for, e.g., a pressure drop in such tubing.

Adaptive patient circuit compensation with pressure sensor at mask apparatus

An improved patient interface assembly and pressure support system integrate a pressure sensor and a valve into the patient interface assembly and employs closed loop control between the sensor and the valve in order to limit delay between the time at which a condition indicative of abnormal breathing or flow load during normal breathing is experienced by a patient and the time at which altered pressure support is received by the patient.

Sensor and valve integrated into a patient interface

Feedback information is provided to a subject regarding reception of pressure support therapy, and/or other respiratory support therapy. The feedback information may indicate compliance to a respiratory therapy regimen. The feedback information is provided to the subject by transmitting the feedback information through a communication network to a client device associated with the subject. The feedback information may include a characterization of the therapy received by the subject with respect to a usage goal.

System and method of providing feedback to a subject receiving respiratory therapy via a client device associated with the subject

The lung compliance of a subject that is at least partially self-ventilating is determined. The quantification of lung compliance may be an estimation, a measurement, and/or an approximate measurement. The quantification of lung compliance may be enhanced over conventional techniques and/or systems for quantifying lung compliance of self-ventilating subjects in the lung compliance may be quantified relatively accurately without an effort belt or other external sensing device that directly measures diaphragmatic muscle pressure, and without requiring the subject to manually control diaphragmatic muscle pressure. Quantification of lung compliance may be a useful tool in evaluating the health of the subject, including detection of fluid retention associated with developing acute congestive heart failure.
