Described are methods for improving oxygen saturation in patients suffering from hypoxemia, wherein said patients are receiving a continuous flow of oxygen at 10 L/min and exhibit an initial oxygen saturation of at least about 88%, comprising administering inhaled nitric oxide to said patients in an outpatient setting. Methods for improving quality of life for a hospitalized patient, reducing patient hospitalization time, and reducing costs associated with patient hospitalization are also described.

An inhaler configured and adapted for inhaling an inhalation medium, enriched with active ingredients and/or flavouring substances, includes a cartridge carrier, a storage tank which contains the inhalation medium, a mouthpiece which is associated with the cartridge carrier, and an actuating mechanism for releasing the inhalation medium out of the storage tank in the direction of the mouthpiece. The inhaler has at least one sensor associated with the mouthpiece. The sensor is configured and adapted to detect characteristics of lips of the person using the inhaler and to provide a data signal formed from the characteristics. The sensor is connected to an electronic control unit associated with the inhaler, to which the actuating mechanism is also connected, in such a manner that the inhalation medium is released on the basis of the data signal. A corresponding arrangement and a corresponding method are disclosed.

The present disclosure relates to use of pulsed dose inhaled nitric oxide for treatment of infection, including infection with SARS-CoV2 and the disease state COVID-19.

Systems and methods are provided related to signal conditioning and analysis methods for detecting respiratory events of a human or an animal. Respiratory events detected can either serve as input to a drug delivery system or be a stand-alone breath detection device. Various methods for sensing respiratory events, processing respiratory signals, and analyzing respiratory signals are provided with the goal of enabling accurate and reliable detection of specific types of events in a respiratory cycle.

A medical gas delivery system and a ventilator system are provided. The medical gas delivery system includes an electrolytic gas generation device, a delivery device, and a control unit. The electrolytic gas generation device is used to generate a first gas and a second gas. The delivery device is in fluid communication with the electrolytic gas generation device, and is used to transport a medical gas. The medical gas includes at least one of the first gas and the second gas. The control unit is electrically connected with the electrolytic gas generation device and the delivery device, so as to control a component ratio of the medical gas.

An is an aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.

An apparatus for sensing, the apparatus comprising: a plurality of genetically modified sensors and a transducer array. The plurality of genetically modified sensors comprise a plurality of subsets of sensors wherein the sensors are genetically modified so as to provide an output in response to one or more chemicals. The plurality of genetically modified sensors are genetically modified in a non-correlated manner so that different subsets of sensors are configured to provide a different affinity to different chemicals. The transducer array, comprises a plurality of pixels, wherein different subsets of the plurality of genetically modified sensors are coupled to different pixels so as to cause the pixels to provide outputs dependent upon the genetic modification of the subset of sensors coupled to the pixel. Detection of one or more chemicals by one or more of the genetically modified sensors causes an identifiable output signal to be provided by the transducer array.

Introduced here is a self-contained face mask system with an automated liquid-droplet dispensing mechanism (ADM) for humidification. The enclosure of the self-contained mask system can be comprised of one or more layers of breathable fabric adapted to flexibly conform to the face of a user when worn to form a cavity that is adjacent the nostrils and mouth. The ADM of the face mask system can be comprised of a reservoir in which liquid is stored, a respiratory cycle detector, a timer and controller, and a droplet dispenser that controllably dispenses droplets of the liquid from the reservoir into the cavity for inhalation by the user. The ADM can be contained entirely within the face mask enclosure or supported on the surface of the face mask enclosure such that the self-contained mask system, when worn by a user, can be supported entirely by the head and neck of the user.

Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user. The device may suggest a corrective action based on the type of off-target ventilation detected. The device may also continuously analyze ventilation to determine changes in lung compliance over time and to identify pathological changes over time. The device may work within a network of devices and user interfaces via wired or wireless communication, and is not restricted to or dependent on the type of ventilatory device with which a patient is being supported.
