A device and method for treating high-altitude sickness can include a handheld device, and can deliver a therapeutic amount of nitric oxide to an individual's lungs in order to minimize or treat high-altitude sickness. The device is self-contained and portable, which allows an individual to carry and use the device in high-altitude or other low-oxygen environments.

A system includes a control unit configured to be worn by a subject, and having a wireless transceiver configured to receive and transmit signals and a processor coupled to a memory, at least one respiratory volume sensor mountable to the chest or abdomen of the subject and at least one secondary sensor mountable relative to the subject. The respiratory volume sensor is configured to operably generate one or more volumetric signals representative of a respiratory volume of the subject and communicate the one or more volumetric signals to the wireless transceiver of the control unit. The at least one secondary sensor is configured to operably generate one or more secondary signals and representative of at least one of a physiological, a cardiopulmonary or a metabolic condition of the subject, and communicate the one or more secondary signals to the wireless transceiver of the control unit.

Breathable medical circuit components and materials and methods for forming these components incorporate breathable foamed materials that are permeable to water vapor and substantially impermeable to liquid water and the bulk flow of gases. The materials and methods can be incorporated into a variety of components, including tubes, Y-connectors, catheter mounts, and patient interfaces and are suitable for use in a variety of medical circuits, including insufflation, anesthesia, and breathing circuits.

Systems and methods regarding ventilation of a patient, such as a victim at the scene of an emergency are described herein.

A system is disclosed that includes a breathing apparatus, a touch screen unit and a processing unit. A first content (30) is displayed at a first screen location (30) of the touch screen. Upon a user input, comprising a gesture (35) of one or more gestures, at the first screen location (31), a second content related to the first content (30) is selected and displayed in dependence of the gesture (35) and the first content (30). The first content (30) is free of an indication of the second content, such as an indication comprised in the list of an icon, soft-button or a menu configured to activate the second content upon user selection on the touch screen.

Apparatus and methods automate selection of patient interface(s) according to their size, such as with processing in a processor(s) or in a server(s). Image data captured by an image sensor may be received. The captured image data may contain facial feature(s) of an intended user of the patient interface. The facial features may be captured in association with a predetermined reference feature of known dimension(s). The user's facial feature(s) and the reference feature may be detected in the captured image data. Image pixel data of the image may be processed to measure an aspect of the detected facial feature(s) based on the reference feature. A patient interface size may be detected from standard patient interface sizes based on a comparison between the measured aspect of the facial feature(s) and a data record relating sizing information of the standard patient interface sizes and the measured aspect of the facial feature(s).

There is provided system for monitoring spontaneous breathing of a mechanically ventilated target individual, comprising: a feeding tube for insertion into a distal end of an esophagus of the individual, sensor(s) disposed on the feeding tube at a location such that the sensor(s) is located at the distal end of the esophagus of the individual when the feeding tube is in use, wherein the sensor(s) is positioned for sensing values by contact with the tissue of the esophagus including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, and code for computing an indication of a frequency band of diaphragm movement of the individual according to an analysis of values sensed by the sensor(s), and for adjustment of parameter(s) of a mechanical ventilator for mechanically ventilating the individual, wherein the instructions for adjustment are computed while the feeding tube is in use.

The invention relates to a modular, portable, air purifier device capable of supplying filtered or otherwise conditioned airflow to an individual. More specifically, the present invention provides an air purification system that allows for the remote detection and analysis of local ambient air quality and transmit that information to wirelessly connected devices.

A ventilator (100), includes a basic unit (1) with a cover plate (10). Patient ports (4) are arranged at the basic unit (1) and a user interface (2) is arranged at the cover plate (10). The cover plate (10) can be arranged at the basic unit (1) at different angles in relation to a vertical axis

A respiratory system includes a gas supply unit and a heating and humidifying unit. The gas supply unit includes a gas supply port; the heating and humidifying unit is detachably combined with the gas supply unit. The heating and humidifying unit includes a base, an adapter and a water tank. The base includes a control element, and the adapter is combined with the base and can rotate at least 90 degrees relative to the base. The water tank is detachably combined with the base, and the water tank includes a gas inlet and a gas outlet, wherein when the water tank is combined with the base, the gas inlet penetrates through an aperture of the base to be fluidly connected to the gas supply port, and the gas outlet is fluidly connected to the adapter.
