A dry powder aerosol delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The dry powder aerosol delivery device includes a housing, a cartridge, and a dry powder dispersion mechanism, and at least one differential pressure sensor. The dry powder delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The dry powder aerosol delivery device is then actuated to generate a plume of particles having an average ejected particle diameter within the respirable size range, e.g., less than about 5-6 μm, so as to target the pulmonary system of the user.

A patient interface kit to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to a patients airways including at least the entrance of a patients nares while the patient is sleeping. The patient interface comprising: a nasal cushion having a nasal cushion opening; a mouth cushion having a mouth cushion opening, the mouth cushion including a flexible joint, positioned above the mouth opening, to selectively connect the nasal cushion to the mouth cushion; and a positioning and stabilizing structure to provide a force to hold the nasal and/or mouth seal-forming structures in a therapeutically effective position on a patient's head, the positioning an stabilizing structure including a nasal headgear including upper straps or conduits and a mouth headgear including lower straps, the mouth headgear being selectively connected to the nasal headgear.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

Monitors for evaluating airway procedures, particularly in a pre-hospital environment, are described herein. In an example method, an airway parameter of an individual receiving assisted ventilation is detected by an airway sensor. A monitor determines a metric based on the airway sensor. Further, the monitor performs an action based on the metric.

A system for creating separation between biological surfaces may comprise a hollow body configured for delivery of a fluid to a target location, a fluid supply in fluid-communication with the hollow body, a control element configured to control the delivery of a fluid through the hollow body, at least one first sensor configured to measure at least one parameter of the fluid flowing through the hollow body, at least one second sensor configured to measure at least one parameter of an environment of the hollow body, a feedback control module configured to receive information from one or more of the at least one first sensor or the at least one of the second sensor to control at least one operational function of the system.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.
