摘要： A pressurized flow of breathable gas is delivered to the airway of a subject in accordance with a therapy regimen. The therapy regimen may be designed to maintain oxygenation of the subject. The therapy regimen dictates levels of fraction of inspired oxygen and/or positive end expiratory pressure to maintain a therapeutically beneficial level of oxygenation in a feedback manner. Within the therapy regimen, changes made to fraction of inspired oxygen and/or positive end expiratory pressure automatically and dynamically are constrained by user configured constraints such as the maximum incremental change, amount of time between adjustments, or the maximum rate of change This may provide a level of customization of the automated control of the therapy regime for individual subjects.

摘要： A method for signaling a failure condition of a bearing of a turbocharger that includes a sensor configured for sensing information on off-axis rotor motion. The method entails receiving a stream of information from the sensor, decomposing the stream of information into a set of components representing different frequencies, using a subset of components that represent a range of frequencies known to be indicative of bearing failure to calculate a probability of failure of the bearing, signaling a failure condition of the bearing if the probability of failure exceeds a critical threshold, and if the present indicia of off-axis rotor motion does not indicate a complete failure condition has occurred, determining a time interval until another probability of failure of the bearing will be calculated. The time interval can vary based upon the rate that the probability of failure has changed over multiple time intervals.

摘要： Determining the lung compliance and lung resistance of a subject undergoing respiratory therapy using non-invasive ventilation requires taking the presence of leaks into account. In particular, variable and unintentional leaks at or near a subject interface appliance may be dynamically determined based on an average resistance of the leak orifice of the subject.

摘要： A secondary line purging system (40) having a blower (22) for pressurizing a flow of gas and a first pressure sensor (28) for measuring a first pressure of the flow of gas at or near the blower. The system also includes a secondary line (36) communicating with the blower and a subject circuit (32). The system further includes a second pressure sensor (30) for measuring a second pressure of the flow of gas within the secondary line. A valve system (42) is operable in 1) a first mode of operation to isolate the blower from the secondary line and 2) a second mode of operation to permit communication between the blower to the secondary line to purge the secondary line of obstructions with the pressurized flow of gas. A controller (16) switches operation of the valve system between the first mode of operation and the second mode of operation, based on the first pressure and the second pressure.
