摘要： A patient ventilation system has a flow regulating and gas mixing arrangement connected to an inspiratory channel of the system from which a gas mixture containing oxygen and at least a second gas is delivered to the system's proximal tubing. The proximal tubing further is connected to an expiratory channel and is connectable to a patient. The system further has at least two gas inlets connected to the flow regulating and mixing arrangement, and a gas identification unit in which the at least second gas supplied to the system via one of the gas inlets can be identified. By actively measuring a value that is dependent on the characteristics of the delivered gas, and by correcting the calibration of the flow regulating and gas mixing arrangement and/or the flow meter(s) based on this value, both safety and flow regulation in the system are enhanced.

摘要： 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.

摘要： In a method and breathing apparatus for providing support ventilation to a spontaneously breathing patient a pressure and/or a flow is monitored based on pressure and/or flow measurements, and efforts to inhale or exhale by the patient are detected based on changes in the monitored pressure and/or flow. When a change in the monitored pressure and/or flow indicating an effort to inhale or exhale is detected, the rate of that change is determined and used to calculate a suitable rate of change of pressure applied to the airways of the patient. By changing the applied pressure in accordance with the so determined suitable rate of change, the pressure rise time during inspiration and/or the pressure fall time during expiration can be adjusted to the needs of the patient to ensure efficient and comfortable ventilation.
