摘要： A method (200) for determining compliance of a connecting circuit in a non-invasive ventilator system. The method includes the steps of: (i) providing (210) a non-invasive ventilator system, the system having a flow or pressure controller; (ii) generating (220) a test signal for the flow or pressure controller; (iii) exciting (230) the flow or pressure controller with the generated test signal for a predetermined time period; (iv) obtaining (240), during the excitation of the flow or pressure controller, one or more measurements of the non-invasive ventilator system; (v) determining (250) a vector of the obtained measurements; and (vi) processing (260) the vector to determine an estimate of a physical parameter of the circuit.

摘要： A method (600) for detecting disconnect in a patient care system comprising a conductive circuit (200, 400) formed at least in part by tubing (102/104, 320) between a patient care device (106) and a patient (108). The method includes the steps of: inputting (620), by a signal generation circuit (116) of the patient care device, an excitation signal to the conductive circuit; detecting (630), by a monitoring circuit (118) of the patient care device, a responding signal; comparing (640) the detected responding signal to a predetermined threshold or impedance signature to determine whether a disconnect of the tubing exists; and generating (650), if a disconnect of the tubing exists, an alarm by an alarm circuit (120) of the patient care device.

摘要： A method (800) for estimating patient airway flow in a non-invasive ventilator system includes: (i) determining (830) an estimated gas flow; (ii) determining (840) a proximal pressure error value; (iii) compensating (850) for the determined proximal pressure estimate error value; (iv) compensating (854) for an error in the estimated gas flow; (v) determining (856) an estimated gas flow leak; (vi) monitoring (860) on a breath to breath basis for a leak; (vii) determining (870) a gas flow leak factor; (viii) adjusting (880) the estimated gas flow leak; (ix) detecting (872) a bias on the airway flow estimate; (x) determining (874) that the system is within a quiescent state of a breath; (xi) de -biasing (976) the estimated gas flow to drive the bias to near zero; and (xii) suspending (878) breath to breath bias correction on an immediately subsequent breath.
