Abstract: A respiratory apparatus evaluates accuracy of a pressure sensor, such as when only a single pressure sensor is provided. The accuracy of the pressure sensor may be assessed based on pressure measurement obtained from the pressure sensor and a subordinate or secondary characteristic of the respiratory device such as altitude or atmospheric pressure. A controller or processor may calculate the altitude of the respiratory device based in part on the pressure measurement. In some embodiments, the assessment of the pressure sensor may involve an evaluation of the calculated altitude. In some cases, the assessment of the pressure sensor may involve determining an estimated pressure based on a calculated altitude, and comparing the pressure measurement obtained from the pressure sensor with the estimated pressure.

Abstract: A method for controlling a humidifier of a CPAP device including a controller, the method including controlling a heating element in the humidifier with command signals from the controller, sensing a temperature of a fluid in the humidifier with a sensor in the humidifier that transmits signals to the controller, establishing an acceptable operating range for the signal transmitted to the controller, determining whether the transmitted signal is within the acceptable operating range, if the signal is within the acceptable operating range treating the signal as being indicative of the temperature of the fluid in the humidifier and using the signal to control the heating element, and if the signal is outside of the acceptable operating range, the controller determines the humidifier to be unavailable.

Abstract: 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.

Abstract translation: 呼吸装置评估压力传感器的精度，例如当仅提供单个压力传感器时。 压力传感器的精度可以基于从压力传感器获得的压力测量值和呼吸装置的从属或次要特性（如高度或大气压力）进行评估。 控制器或处理器可以部分地基于压力测量来计算呼吸装置的高度。 在一些实施例中，压力传感器的评估可以涉及对计算出的高度的评估。 在一些情况下，压力传感器的评估可以包括基于计算出的高度确定估计的压力，并且将从压力传感器获得的压力测量值与估计的压力进行比较。
