Abstract: A system and method is disclosed for performing diagnostics on patient devices (720). The patient devices (720) may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server (710) may maintain a database of diagnostic data (718) indicating faults in one or more of a plurality of patient devices (720). The server (710) may transmit this diagnostic data (718) to one or more computing devices (760), including identification of faults that have occurred. The server (710) may also transmit service data to the plurality of patient devices (720) in order to address the identified faults.

Abstract: A system and method for updating patient devices is disclosed. The patient devices (720, 730, 740) may include respiratory therapy devices (4000) that operate in accordance with instruction sets (726), such as software or firmware. A server (710) may maintain a database of configuration data (718) indicating the versions of the software and firmware that is currently installed on the patient devices (720, 730, 740). The server (710) may also transmit updated instructions (716) from over a network (4282), including a wireless network. Particular patient devices (720, 730, 740) may be selected for updating based on the configuration data (718). Upon performing an update a patient device (720, 730, 740) may transmit configuration data (728) to the server (710).

Abstract: A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments.

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: An over-pressure control device prevents over-pressure conditions during the delivery of pressure treatment therapy to a patient with a respiratory treatment apparatus. The device may prevent delivered pressure from exceeding a first maximum pressure threshold. The device may also prevent the delivered pressure from exceeding a second maximum pressure threshold when the delivered pressure exceeds another pressure threshold for a period of time. In some embodiments, the second maximum pressure threshold may be lower than the first maximum pressure threshold. In an example embodiment, a set of comparators are configured to compare pressure with a maximum pressure threshold and to control a reduction in the pressure if the pressure exceeds the maximum pressure threshold. The set may also be configured to compare the pressure with a pressure threshold and to control reduction in the maximum pressure threshold if the pressure exceeds the pressure threshold for a period of time.
