A vaporizer arrangement for a breathing apparatus serves the double purpose of vaporizer and pressurized supply of vapor-containing gas for direct delivery to a patient. The vaporizer arrangement has at least a first gas inlet channel for conveying a flow of a carrier gas into a vaporization chamber, a vaporizer for vaporizing a liquid into the carrier gas in the vaporization chamber, and a gas outlet channel for conveying a flow of vapor-containing carrier gas out of the vaporization chamber and toward the patient. The vaporizer arrangement further has a gas flow regulator that maintains the carrier gas within the vaporization chamber at an overpressure, and that controls the flow of vapor-containing carrier gas out of the vaporization chamber in a variable manner.

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.

Abstract to be published with FIG. 4C

A gas tank arrangement for a breathing apparatus, including: a gas tank; an inlet valve configured to control a flow of gas into said gas tank; an outlet valve configured to control a flow of gas out of said gas tank and towards a patient; and a controller configured to control said inlet and outlet valves to maintain the gas within said gas tank at an overpressure for subsequent delivery to the patient, to control the outlet valve based on a parameter that is indicative of pressure within the gas tank, and to control the inlet and outlet valves to always maintain the pressure in the gas tank between a minimum pressure threshold value and a maximum pressure threshold value, wherein the minimum or maximum pressure threshold value is determined based on preset parameters relating to the dynamics of said outlet valve, or a desired minimum or maximum flow of gas out of the gas tank.

A system for controlling patient sedation and spontaneous breathing intensity includes a ventilator system that delivers ventilation to the patient. The system further includes a spontaneous breathing control module configured to determine a first spontaneous breathing intensity at a first sedative status of the patient, and a second spontaneous breathing intensity at a second sedative status of the patient. A sedation/breathing relationship is then defined between spontaneous breathing intensity and sedative status for the patient based on the first and second sedative statuses and the first and second spontaneous breathing intensities. The spontaneous breathing control module then receives a desired spontaneous breathing intensity for the patient and determines a desired sedative status that achieves that desired spontaneous breathing intensity based on the sedation/breathing relationship.

A system includes a breathing apparatus, a touch screen unit and a processing unit. A first content is displayed at a first screen location of the touch screen. Upon a user input, comprising a gesture of one or more gestures, at the first screen location, a second content related to the first content is selected and displayed in dependence of the gesture and the first content. 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.

A method of controlling a flow rate of gases supplied to a patient by a respiratory assistance device includes controlling the supply gases flow rate so as to deliver gases to the patient according to a predetermined gases pressure/flow rate profile for at least a portion of the breathing cycle. A profile may be achieved that provides the patient with a particular benefit or therapy.

An anesthesia system includes a volume reflector, a breathing circuit, a processing unit, and a display operatively connected to the processing unit. The processing unit is configured to provide a status indicator on the display for gas in the volume reflector, the status indicator including a graphical representation of an extent of a driving gas of the volume reflector and/or a patient gas in the volume reflector, and/or a flow of gas and a direction of the flow in the volume reflector, and/or a waste gas flow out of the volume reflector relative a fresh gas flow in the system, and/or a re-breathing fraction (RBF), and/or a balance between the fresh gas flow and patient uptake and/or leakage of gas from the breathing circuit.

A system includes a patient support unit having an enclosed patient environment, a heating module, a skin temperature sensor module, an environmental sensor module, and a control system. The control system is configured to selectively operate the system in a pre-programmed weaning mode configured to gradually wean the patient from the warmed patient environment series of stepped air temperature decreases performed over a series of stepped time durations achieves a goal air temperature while maintaining a goal skin temperature within a weaning abort deviation.

An anesthetic breathing apparatus has a processing unit, a breathing circuit for providing an inspiratory patient gas mixture of re-breathed gas and/or fresh gas to a patient fluidly connected to the breathing circuit, and a fresh gas supply controllable by the processing unit for supplying a flow of the fresh gas to the breathing circuit in a composition including oxygen and at least one anesthetic agent (AA). A user interface includes a first user input element for receiving operator input for an anesthetic target value including an end expiratory concentration of the AA (EtAA) target value and/or an end expiratory minimum alveolar concentration (EtMAC) target value of an end expiratory MAC value of the patient, and a second user input element for receiving operator input for a desired control profile for the fresh gas supply for obtaining at least the anesthetic target value. The inspiratory patient gas mixture is controlled based on at least the anesthetic target value, the oxygen target value, and the desired control profile.
