摘要： A controller or processor for a respiratory pressure treatment device determines an estimate of patient respiratory flow based on a measure of pressure associated with flow generated by a flow generator and a measure of frequency of the flow generator, such as a rotational velocity of a servo-controlled blower motor. The estimate can be made without data from a flow sensor. The measure of frequency may be converted to an expected pressure based on characteristics of the flow generator and subtracted from the measured pressure to determine the flow estimate. The flow estimate can be implemented in the provision of respiratory pressure treatment with the flow generator. For example, the flow estimate may be utilized to trigger expiratory pressure relief during a patient's expiration as detected with the estimated flow signal.

摘要： A CPAP system includes a flow generator (10), a patient interface (50), an air delivery conduit (20) that interconnects the flow generator and the patient interface, wherein the air delivery conduit has an internal diameter of less than 19 mm. Preferably the air delivery conduit has an internal diameter of between about 10 mm and about 18 mm. The CPAP system may also include a controller for compensating for pressure swings and/or increased impedance within the system. Preferably the blower includes a low inertia blower.

摘要： Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14,16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.

摘要： A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.

摘要： A flow generator for delivering breathable gas to a patient includes a processor coupled with operation sensors and a user interface. The processor is programmed to generate at least one of time-based or event-based messages relating to at least one of flow generator operation, flow generator service, flow generator use, patient health, peripheral devices and services, patient treatment, and reminders. Time-based messages are generated at predetermined time intervals based on either time of use or elapsed time. The event-based messages are generated based on signals from the operation sensors. The user interface is configured to deliver the messages to at least one of a display, a flow generator service provider, the patient and a physician. By this system, operation of the flow generator is facilitated and enhanced.
