    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: 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: In a method for continuous and non-invasive determination of the effective lung volume, the cardiac output, and/or the carbon dioxide content of venous blood of a subject during a sequence of respiratory cycles, the inspiratory and expiratory flow, and the carbon dioxide content of at least the expiration gas are measured. In each respiratory cycle, a first parameter related to the subject's fraction of alveolar carbon dioxide, a second parameter related to the carbon dioxide content of the subject's arterial blood, and a third parameter related to the subject's carbon dioxide elimination are determined based on the measured inspiratory flow, expiratory flow and carbon dioxide content. The effective lung volume, the cardiac output, and/or the carbon dioxide content of venous blood of the subject is determined based on the correlation of the first, second and third parameters.

    摘要: An anaesthetic delivery system has a ventilation arrangement with an inspiration gas pathway for conducting inspiration gas to a patient and an expiration gas pathway for conducting expiration gas away from the patient, and a filter element serially connected to both the inspiration and the expiration gas pathways. The filter element retains anaesthetic from expiration gas passing therethrough and releases the retained anaesthetic into inspiration gas passing therethrough. A supply of flushing gas is communicable with the filter element to flush the retained anaesthetic from the system without passing to the patient.

    摘要: An apparatus front panel has a mechanical user interface in the form of a mechanically controllable regulation and setting elements on the face of the front panel. The front panel is manufactured at least in part from a transparent material in which electrical conductors and components are arranged in order to electrically connect the controllable regulation and setting elements from the face of the front panel with the electrical equipment present in the apparatus via a front panel connection. The front panel is constructed so that it can be attached at least in part to a substantially flat indicia-bearing element such as in front of a screen, in front of a display, or over a printed base or the like.

    摘要: A breathing apparatus has a first delivery device for adding a volume of a substance to a gas flow, the delivery device having a gas inlet and a gas outlet. A unit monitors a presence of the substance in a gas downstream the delivery device using a first sensor unit at the gas outlet that provides a first measurement value based on an acoustic property of a gas in a first conduit. A second sensor unit at the gas inlet provides a second measurement value based on an acoustic property of a gas present in the second conduit. A control unit determines the presence of the substance based on the first measurement value or based on a comparison of the first measurement value and the second measurement value.
