Devices and methods provide system characterization, such as for operation of a respiratory therapy device. Pressure and flow signals from a therapy session may be analyzed to determine a profile representing pressure and flow characteristics of the system, such as where the system includes a delivery catheter and a patient interface having a vent. A pressure drop parameter may be derived based on a first function characterizing the curve and a second function characterizing a curve representing pressure and flow characteristics of a component of the system such that the parameter is characteristic of a pressure drop from a sensor in the therapy generator to the patient interface. The parameter may be derived from a difference between the first function and the second function. A signal for controlling the therapy generator may be generated to adjust a characteristic of the supplied airflow based on the pressure drop parameter. 设备和方法提供诸如用于呼吸治疗设备的操作的系统表征。可以分析来自疗法会话的压力和流量信号以确定表示系统的压力和流量特征的曲线，诸如在该系统包括递送导管和具有通气口的
