An apparatus for humidifying a flow of breathable gas includes a water reservoir and a water reservoir dock forming a cavity structured and arranged to receive the water reservoir in an operative position. The water reservoir comprises a reservoir base including a cavity structured to hold a volume of water, the reservoir base including a main body and a thermally conductive portion provided to the main body. The thermally conductive portion comprises a combined layered arrangement including a metal plate and a thin film, the thin film comprising a non-metallic material and including a wall thickness of less than about 1 mm. The thin film is adapted to form at least a bottom interior surface of the water reservoir exposed to the volume of water, and the metal plate is adapted to form a bottom exterior surface of the water reservoir.

A ventilator analysis unit (100) detects a disconnection of a pneumatic connection to a ventilated patient. A data acquisition module (110) receives gas flow data (112) indicating gas flow at the transition to the patient and gas pressure data (114) indicating a transition gas pressure. The memory module (120) provides a disconnection value function (122) describing the transition gas flow transition gas pressure association with a disconnection value (132). The calculation module (130) calculates a disconnection value based on the gas flow data and the gas pressure data via the current disconnection value function and determines a disconnection number (134) from a chronological sequence of correspondingly calculated, current disconnection values. The calculation module further indicates a presence of a disconnection of the pneumatic connection via a corresponding output (140) if the disconnection number reaches a predefined threshold value or is above the predefined threshold value over a predefined time period.

Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or. The ventilator system allows for independent titration of PEEP, pCO.sub.2 and pO.sub.2 with no need for permissive hypercapnia.

A respiratory therapy system for providing continuous positive air pressure (CPAP) to a patient may include a flow generator for generating a supply of breathable gas, a sensor to measure a physical quantity while the breathable gas is supplied, and a computing device. The computing device may be configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control the flow generator to adjust a property of the supply of breathable gas; display a question and a plurality of selectable responses; receive a first input selecting one of the selectable responses; and display a coaching response corresponding to the selected response.

Condensation or “rain-out” is a problem in breathing circuits and especially neonatal breathing circuits. The subject patent provides an improved breathing tube component for managing rain-out particularly in neonatal applications. In particular the breathing tube has a smooth inner bore, and an outer insulating layer containing stagnant gas and a heater wire.

An apparatus for delivering a flow of gas has a housing and a humidifier. The housing has a recess for a motor and/or sensor module, an outlet port for a flow of gas, and a removable elbow for a flow of gas. The humidifier has a heater, a chamber bay for receipt of a liquid chamber, and a lever and/or detent(s) for assisting with insertion and/or retention and/or removal of the liquid chamber in and/or from the chamber bay.

An air delivery tube for a CPAP system includes a first end configured to connect to a flow generator of the CPAP system and a second end configured to connect to a patient interface of the CPAP system. The air delivery tube also includes a central lumen that is formed by an inner wall of the air delivery tube and is configured to convey pressurized breathable gas from the first end to the second end. In addition, a circumferential chamber surrounds the central lumen and is configured to retain a supply of water. A wick is located within the central lumen and is connected to the inner wall.

Humidifier apparatus for a respiratory apparatus includes a housing providing a gas flow path, a heater apparatus, and a water supply distribution member configured and arranged to deliver water vapour to the gas flow path. The water distribution member is provided to the housing and in thermal communication with the heater apparatus.

This invention relates to a patient interface, a system and/or method for providing a dedicated or sole inspiratory line or conduit for provision of inspiratory gases to a patient, and a dedicated sole expiratory line or conduit for provision of expiratory gases to a downstream device, where the inspiratory line or conduit is sealing engageable with first of a user's nares and the expiratory line or conduit is sealing engageable with the second of a user's nares.

A system may limit the number of times an inhalation device transmits inhalation data to a single time to reduce the battery usage of the inhalation device. The system may include an inhalation device that has medicament and an electronics module. The system may limit the number of times the inhalation device transmits new inhalation data to any mobile device to a single time by causing the server to receive the new inhalation data from one of the mobile devices and causing the server to transmit the new inhalation data to other of the mobile devices prior to the other mobile devices transmitting a request for the new inhalation data to the inhalation device. The inhalation device may include a Quick Response (QR) code, and a mobile application may determine at least one of a medication type or a number of doses of the inhalation device from the QR code.
