A method and system for diagnosing, treating, and ameliorating sleep bruxism events using a positive airway pressure (PAP) system for treating obstructive sleep apnea to concurrently recognize bruxism events. At least one sensor is integrated into a therapy interface and/or headgear to detect physiological signals indicative of bruxism. In some exemplary embodiments, a loudspeaker and microphone are integrated into the interface, either near the nose or near the mouth of the patient. When integrated near the nose, the pair is used for acoustical rhinometry, and when integrated near the mouth, the pair is used for acoustical pharyngometry. In other exemplary embodiments, sound or vibration sensors are used to detect signals indicative of teeth grinding. In response to sensor detection of bruxism activity, the PAP system controller adjusts the PAP therapy settings or proposes alternative treatment modalities in order to stop or prevent bruxism events.

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

A humidification control system comprises a ventilation therapy apparatus main body, a respiratory humidifier, a heating pipeline and a nasal oxygen cannula, wherein the ventilation therapy apparatus main body comprises a fan and a first controller, the respiratory humidifier comprises a water tank, a heating plate, a water tank air inlet temperature sensor and a heating plate temperature sensor, an air outlet of the fan is connected to an air inlet of the water tank; an air outlet of the water tank is connected to an air inlet of the heating pipeline; an air outlet of the water tank is connected to an input port of the nasal oxygen cannula; the heating pipeline comprises a heating pipeline air inlet temperature sensor and a heating pipeline heating control module; and the first controller makes the relative humidity of the current first mixed airflow.

The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

A therapeutic vaporizer inhalation bag attachment system with an integrated valve is disclosed. The attachment system includes a body having a lumen extending between the two openings of the body, a bag coupling, and a valve positioned within the lumen. A method of using the inhalation bag attachment system is also disclosed.

A method includes receiving physiological data associated with a user during a sleep session. The method also includes determining a sleep-wake signal for the user during the sleep session based at least in part on the received physiological data. The method also includes determining one or more sleep-related parameters for the user during the sleep session based at least in part on the sleep-wake signal. The method also includes determining that the user experienced insomnia during the sleep session based at least in part on at least one of the one or more sleep-related parameters. The method also includes identifying a type for the insomnia experienced by the user based at least in part on the one or more sleep-related parameters.

Algorithms for detecting endotracheal intubation and/or misplacement of endotracheal tubes in child patients during anesthesia for use with anesthesia machines, mechanical ventilators, and/or respiratory function monitors. An algorithm uses end-tidal carbon dioxide (EtCO.sub.2), and tidal volume (TV) or peak inspiratory pressure (PIP) to detect exact intubation time. Another algorithm uses respiratory parameters to identify and/or confirm the type of airway device used during mechanical ventilation, and to detect if and when an issue has arisen with use of a specific airway device to provide real-time decision support to attending medical care professionals.

An endotracheal tube to bag valve device connecting assembly for quick access to an endotracheal tube for suctioning includes a first tube and a second tube that are coupled to a hinge so that the first tube is positioned to be swiveled relative to the second tube to align the first tube with the second tube, wherein the first tube and the second tube define a pipe. A first end of the pipe is configured to selectively couple to a patient valve of a bag valve device. A second end of the pipe is configured to selectively couple to an endotracheal tube. The pipe is configured to allow flow of gas from the bag valve device to the endotracheal tube. The first tube is positioned to be swiveled on the hinge so that the second tube is configured to insert a suction tube into the endotracheal tube to clear an airway.

Devices for delivering a controlled concentration of an agent are provided. The device includes a reservoir for the agent and a flow control portion operably connected to the reservoir. The device also includes a valve for releasing the agent from the flow control portion and a pump for flowing air to mix with the agent released by the valve and for flowing the agent and air mixture out of the device. Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.

Apparatus is disclosed for ventilation using an airbag, which may also be operable manually. The apparatus comprises: means providing or penetrable to form an aperture in the airbag; retractable means provided separately from the airbag, for extending in the airbag; fixing means for fixing, by an operator, an end of the retractable means to the airbag via the aperture; actuation means, for repeatedly retracting the retractable means at least partially through the aperture in the airbag to collapse the airbag, and for enabling expansion of the airbag to an expanded state; and connecting means for connecting the actuation means to the airbag and for preventing environment egress of gas from within the airbag between the aperture and the actuation means.
