摘要： A continuous positive airway pressure (CPAP) apparatus for respiratory assistance of a pattern is disclosed. There is a blower having an output connectible to a ventilation mask wearable by the patient. A first pressure sensor measures blower pressure at the output of the blower, and a second pressure sensor that is connectible to the ventilation mask measures mask pressure therein. A pressure controller is connected to the first pressure sensor and the second pressure sensor, and a patient inspiratory phase and a patient expiratory phase is be detectable by the pressure controller to regulate therapeutic pressure at the patient mask, based upon pressure differentials between the mask pressure and the blower pressure.

摘要： Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface.

摘要： A respiratory assistance device is disclosed. There is a patient interface for coupling to a patient respiratory passageway, and a selectively regulated therapeutic gas flow source in pneumatic communication with the patient over the patient interface. A ramping controller is connected to the therapeutic gas flow source and is receptive to inputs of a prescription pressure level, an initial pressure level, a total ramp duration, and a numeric value corresponding to a ramping duration. Therapeutic gas flow at an initial pressure level is regulated for a ramp delay duration reciprocal to the ramping duration relative to the total ramp duration. The ramping controller incrementally increases therapeutic gas flow to the prescription pressure level from a ramp start time to a ramp end time at a delivery pressure increase rate derived from the numeric value of the ramping duration and the total ramp duration.

摘要： A control system for a variable-geometry turbocharger includes a supervisor logic (12) selecting a pulse control output (24) for large variation of desired and previous control signal inputs exceeding a threshold differential and a normal control signal (26) for small control signal input changes. The control system calculates an amplitude and duration for the pulse control output based on input control signal variation or the actual versus desired position of the variable-geometry system in the turbocharger.
