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.

A snore blocking helmet for comfortably minimizing snore impact on others includes a helmet body having a front portion, a rear portion, a right portion, a left portion, a top portion and a bottom perimeter forming an inside. The front portion has a visor aperture and a plurality of vent apertures extending through to the inside. A visor is rotatably coupled to the helmet body to cover and alternatively uncover the visor aperture. A plurality of fans is coupled within the inside adjacent the plurality of vent apertures. A control housing is coupled through the front portion. A plurality of controls is coupled to the control housing and is in operational communication with the plurality of fans. A power source is coupled to the control housing and is in operational communication each of the plurality of controls and the plurality of fans.

A seal-forming structure for a patient interface may include a patient-contacting surface configured to engage the patient's facial skin to form a seal; a posterior opening formed in the patient-contacting surface, the posterior opening configured to provide the flow of air at said therapeutic pressure to the patient's nares; and a support structure extending from the patient contacting surface to an interior surface of the seal-forming structure, the support structure and the interior surface forming a continuous loop, wherein the patient interface is configured to allow the patient to breath from ambient through their mouth in the absence of a flow of pressurised air through the plenum chamber inlet port, or the patient interface is configured to leave the patient's mouth uncovered.

A personal breathing apparatus installed in an aircraft that is not fully pressurized, and configured to prevent or treat an adverse physiological event. The personal breathing system is configured so as to prevent, lessen or reverse hypercapnia by (i) facilitating removal of carbon dioxide generated the pilot by controlling pilot ventilation and/or (ii) limiting or decreasing the amount of carbon dioxide generated by the pilot by controlling the amount of oxygen breathed by the pilot.

A method and system to manage a respiratory condition of a patient. An oxygen concentrator is configured to generate and deliver oxygen enriched air to the patient according to a selected dosage. The oxygen concentrator senses and collects physiological data of the patient and collects operational data during the generation and delivery of oxygen enriched air. The oxygen concentrator adjusts the dosage of oxygen enriched air based on the sensed physiological data. The oxygen concentrator transmits operational data and the physiological data to a health data analysis engine. The health data analysis engine collects the data transmitted by the oxygen concentrator. The health analysis engine detects a triggering event based on the collected data and determines an action to resolve the detected triggering event.

Embodiments provide an oxygen supply device having multiple operational states including a first state and a second state. In the first state, the oxygen supply device is controllable to a local control instruction such that the oxygen supply device can be operated by a user physically located within a proximity of the oxygen supply device. In the second state, the oxygen supply device is only controllable to a remote-control instruction such that the oxygen supply device can be operated by a user remote to the oxygen supply device. For example, the user can be located in an office remote to a location of the oxygen supply device, which, for example, may be placed at a patient's home. In the second state, the user is enabled to control the oxygen supply device from a device associated with the user in the remote location.

A portable medical ventilator using pulse flow from an oxygen concentrator to gain higher oxygen concentration includes a positive pressure source to deliver pressurized air to the patient and a negative pressure source to trigger the oxygen concentrator. A patient circuit attached to a patient interface mask connects the ventilator to the patient. The ventilator includes a controller module that is configured to generate a signal to the negative pressure device to trigger the concentrator to initiate one or more pulses of oxygen from the oxygen concentrator. The oxygen pulses are delivered to the patient interface directly through multi-tube or a multi lumen patient circuit. The oxygen does not mix with air in the ventilator or in the patient circuit and bypasses the leaks in the patient circuit and/or patient interface.

A mechanical ventilation device comprising at least one electronic controller is configured to receive images of lungs of a patient undergoing mechanical ventilation therapy with a mechanical ventilator, the images being acquired over time and having timestamps; process the images to generate timeline images at corresponding discrete time points; and display a timeline of the timeline images on a display device.

The present disclosure provides systems and method for electric plasma synthesis of nitric oxide. In particular, the present disclosure provides a nitric oxide (NO) generation system configured to produce a controllable output of therapeutic NO gas at the point of care.

A user interface of a respiratory therapy system includes a strap assembly, a frame, a connector, and a sensor. The strap assembly is positioned about a head of a user when the user wears the user interface. The frame is physically and electrically connected to the strap assembly, and defines an aperture. The connector has a first end portion and second end portion. The first end portion of the connector can be positioned within the aperture of the frame such that the connector is physically and electrically connected to the frame. The sensor is coupled to the strap assembly or the frame such that the sensor abuts a target area of the user when the user wears the user interface.
