    摘要： In a method, ventilator and ventilator control unit for determining an end-expertorial lung volume (EELV) for a mechanically ventilated patient, a breathing gas is provided to the patient that has a first fixed N2/O2 gas composition, at least until the N2/O2 gas composition in air expired from the patient is constant. At least once, at a first predetermined point in time, the N2/O2 gas composition in the breathing gas is changed to a second fixed composition. The change in the N2/O2 gas composition exhaled by the patient for each breath is measured until a second point in time at which the level of expired O2 in at least two subsequent breadths is substantially stable. The measurement is made downstream of the expiratory tube of the ventilator. The total gas volume is determined for each breath, and the EELV of the patient's lungs is determined based on the change in O2 level between the first and second points in time.

    摘要： An anesthetic delivery system has a delivery unit containing a carbon dioxide retaining element and a reversible action anesthetic absorber/desorber for releasably retaining therein at least a portion of a charge of anesthetic agent. An externally accessible first internal flow section in the delivery unit directs gas through the delivery unit first through the anesthetic absorber/desorber and then through the carbon dioxide retaining element, sequentially. An externally accessible second internal flow section directs gas through the delivery unit via the anesthetic absorber/desorber and bypassing the carbon dioxide retaining element.

    摘要： An anaesthetic device has a manual ventilation bag, a mechanical ventilator and a user interface for setting an operating mode, including mechanical ventilation via the mechanical ventilator and manual ventilation via the manual ventilation bag, and for setting parameter values for the operating mode that has been set. The anaesthetic device further has a remote control for wireless transmission of commands to the user interface. The user interface is adapted to carry out the commands from the remote control only when the anaesthetic device is set for manual ventilation.

    摘要： A flexible patient cassette that can be optimized for different types of breathing circuits, different drive circuits and different patient categories has a first inlet arranged to be connected to a drive circuit, and at least a second inlet arranged to be connected to a patient connector, the first and second inlets being pneumatically connected with each other through a gas conducting passage constituting a patient circuit having a certain volume. The patient cassette has a volume-varying arrangement for varying the patient circuit volume to allow that volume to be varied in dependence of at least one of the type of breathing circuit in which the patient cassette is used, the type of drive circuit to which the patient cassette is connected, and the tidal volume of a patient connected to the patient connector.

    摘要： A delivery apparatus for pressurized medical liquids has a primary reservoir that pressurizes a medical liquid therein to a driving pressure, a second reservoir having an inlet connected to receive pressurized liquid from the primary reservoir via a controllable intermediate valve, and an outlet for discharge of the received medical liquid via a controllable dosing valve. A pressure measuring unit measures the pressure in the secondary reservoir and a control unit controls the intermediate valve and the dosing valve by monitoring the operation of the intermediate valve and the dosing valve dependent on the measured pressure value from the pressure measuring unit. The control unit generates a status signal dependent on predetermined rules for measured pressure changes compared with calculated pressure changes.

    摘要： The invention relates to an arrangement in connection with a feedback control system, the arrangement comprising a controllable device (10), a measuring device (7), a controlling device (9) and a user interface by which the controlling device (9) can be monitored by means of set values. The measuring device (7) is adapted to measure a measuring value (8) from a measuring point, which measuring value is dependent on the operation of the controllable device and the controlling device (9) is adapted to monitor the controllable device (10) on the basis of the measuring value and set values. To improve safety, the arrangement comprises means (15a, 15b, 15c) adapted to feed a reference signal (16) to the measuring device (7) periodically. The controlling device (9) is adapted to compare a measuring value (18) obtained from the reference signal with the real reference value (17) of the reference signal and adapted to take a safety measure when the measuring value (18) and the real reference value (17) differ substantially from each other.
