A system is for alarm management in connection with a lung recruitment manoeuvre performed by a breathing apparatus on a mechanically ventilated patient. The system is configured to obtain information on at least one optimized ventilation setting for the patient, determined during the lung recruitment manoeuvre, and to automatically initiate at least one alarm setting for a period of ventilation following the recruitment manoeuvre, based on the optimized ventilation setting.

A respiratory valve, such as a positive end expiratory pressure valve, permits pressure control for respiratory apparatus such as a ventilator or positive airway pressure device. The valve may include a flexible gas passage cover. The cover may be configured with a first side surface to operatively block and open an aperture of the gas passage at a valve seat to respectively prevent and permit gas flow through the aperture defined by the valve seat. The cover may include a second side surface opposite the first surface. The second surface may include at least one drop section forming a reduction in thickness of the cover between the first surface and the second surface. The first surface may include a coating to reduce friction of a membrane material of the first surface. The rim of the valve seat may comprise a variation in height relative the flexible cover.

A breathing assistance device includes a gas regulating valve. The gas regulating valve is operated by a linear actuator. The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.

A mask device which can appropriately detect exhalation of a patient is provided with a mask body installed on the patient, an exhalation tube having an exhalation flow path through which the exhalation of the patient runs and used for detecting the exhalation, and an oxygen tube used for supplying oxygen to the patient; the mask body is provided with an oxygen supply port to which the oxygen tube is connected and an exhalation tube support part which can support the exhalation tube; and the exhalation tube support part is structured so as to support the exhalation tube with changing at least one distance of a distance between a tip end of the exhalation tube and a nose part of the patient or a distance between the tip end of the exhalation tube and the mouth part of the patient.

Various methods and systems are provided for determining a quality of a medical gas flow. In one example, a method for a medical gas quality monitoring system includes obtaining measurements of a medical gas via a plurality of sensors, the plurality of sensors including at least one of a humidity sensor, a particulate matter sensor, a carbon dioxide sensor, and a total volatile organic compound (tVOC) sensor, determining a gas quality index of the medical gas based on the obtained measurements, and outputting the determined gas quality index.

Disclosed is a ventilator with an apparatus input and an apparatus output and with an airway between the apparatus input and the apparatus output. A breathing gas drive, a non-return valve and a switching valve are arranged in the airway. The non-return valve prevents a flow of breathing gas in a direction from the apparatus output to the apparatus input and the switching valve enables at least temporarily a flow of breathing gas in a direction from the apparatus output to the apparatus input.

A breathing apparatus includes a control unit configured to control operation of the breathing apparatus based on at least a first input value and a second input value. The breathing apparatus also includes a graphical user interface connected to the control unit. The control unit is configured to display a visual output on the graphical user interface including an area defined by a first axis and a second axis. In addition, the breathing apparatus includes an input unit configured to provide selection of a portion of the area. The control unit is configured to set the first input value in response to the position of the selected portion relative the first axis and to set the second input value in response to the position of the selected portion relative the second axis.

Systems and methods for monitoring pulmonary edema and/or pulmonary congestion are based on changes in impedance parameters that are indicative of lung impedance of a patient. Early detection of changes in the status of a patient pertaining to pulmonary edema and/or pulmonary congestion may be especially beneficial for heart failure patients. Quantification is based on differentials, e.g. within a span of 24 hours, of one or more lung impedance parameters.

A device, a process and a computer program influence the breathing of a person. The device (10) for influencing the inspiratory muscles of a person (20) includes a detection device (12) for detecting an electromyographic signal of the person; a breathing influencing device (14) and a control device (16) for controlling the detection device (12) and the breathing influencing device (14). The control device (16) is configured to determine information on a muscle state of an inspiratory muscle of the person (20) on the basis of the electromyographic signal. The control device (16) is further configured to operate the breathing influencing device (14) as a function of the information on the muscle state in a training mode, which is limited in time, with a training intensity.

A diagnostic tool can include a face mask, a casing, a plurality of sensors, and processing circuitry. The face mask can include an air-intake port, a first check valve integrated into the air-intake port, an air-exhaust port, and a second check valve integrated into the air-exhaust port. The casing can be coupled to the face mask having an air-intake chamber coupled to the air-intake port and an air-exhaust chamber coupled to the air-exhaust port. The processing circuitry can be communicatively coupled to the plurality of sensors. The processing circuitry can include computing logic for handling information detected by the plurality of sensors.
