Methods and apparatus provide communications among respiratory therapy device ('TD'), server and intermediary (e.g., a control device (“CTLD”) for the therapy device) to improve security. More secure communication channel(s) may be established using shared secrets derived with different channels. The communications may include transmitting therapy data from TD to server for authentication. The CTLD may receive the data and a nonce from a server. The CTLD receives from the TD a signing key dependent on the nonce and a secret shared by TD and server. The CTLD generates an authorisation code with received therapy data and the key for authentication of the data by the server upon its receipt of the code and data. The server computes (1) a key from the nonce and the secret known to TD, and (2) another authorisation code from received therapy data and the key. Data authentication may involve comparing received and computed codes.

Secure networked respiratory therapy systems

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

Remote respiratory therapy device management

A server is provided and is programmed to automatically determine, based on the identification data that uniquely identifies a patient device, whether there is an upgrade to the code or data (e.g., software or firmware) stored in the electronic memory of the patient device that can be applied thereto. In response to determination that there is an upgrade that can be applied, a data package is delivered to the patient device via the first wireless transceiver, the data package to be automatically applied to the electronic memory of the patient device.

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

Remote diagnostics of respiratory therapy devices

A system for providing continuous positive air pressure therapy is provided. The system includes a patient interface, a flow generator, a sensor, and a computing device. Wireless transceivers allow wireless communication between the computing device and the flow generator and/or patient interface. Sensor data is communicated to the computing device and a leak determination is made by the computing device based on the sensor data. If a leak is detected, then troubleshooting options for correcting the leak are displayed to the patient on a display of the computing device. The troubleshooting options may be selected based on the sensed data, the type of patient interface, the type of flow generator, or characteristics of the patient using the device.

Systems and methods for setup of CPAP systems

In a respiratory apparatus for treatment of sleep apnea and other disorders associated with an obstruction of a patient's airway and which uses an airflow signal, an obstruction index is generated which detects the flattening of the inspiratory portion of the airflow. The flattening index serves as an obstruction index used to differentiate normal and obstructed breathing. The obstruction index is based upon comparison of values of airflow in different sectors of the inspiratory peak of the wave function and is particularly suitable for distinguishing M shaped or square shaped respiratory patters patterns indicative of partially obstructed airways.

Method and apparatus for improved flow limitation detection of obstructive sleep apnea

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. The discrete modules of the medical treatment apparatus may include tamper resistant locking mechanisms to impede unauthorized separation of some modules.

CPAP treatment apparatus is disclosed having a controllable positive airway pressure device. A sensor generates a signal representative of patient respiratory flow that is provided to a controller. The controller is operable to determine the occurrence of an apnea from a reduction in respiratory airflow below a threshold determined from long term ventilation. When an apnea or hypopnea has occurred the calculation of the threshold is suspended until the end of that event.
