    摘要: A device is directly or indirectly connectable to a patient for determining a volume related to the lungs of the patient. The device has an inspiration part through which a breathing gas passes towards the patient, and an expiration part through which the breathing gas passes away from the patient. The inspiration part has a mouthpiece for introducing a change of the gas composition in the breathing gas. The device implements a method for determining the volume with a detector being arranged in the expiration part that measures a measuring parameter which is dependent on the change in the gas composition, and with a calculation unit connected to the detector unit that determines the variation in the measuring parameter, and determines the volume from the determined variation.

    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.

    摘要: In a method and apparatus for monitoring the composition of a breathing gas mixture having a first gaseous component and a second gaseous component, a data processor is supplied, either as an input value or as a measured value from associated humidity sensors with an indication of a moisture content value (RHComp1) for the first gaseous component and a moisture content value (RHComp2) second gaseous component before mixing. An indication of the moisture content value for the mixture (RHMix) is measured and provided to the data processor. From these inputs the data processor determines a value indicative of the amount (x,y) of one or both of the first gaseous component and the second gaseous component in the mixture according to the relationship: RHComp1·x+RHComp2·y=RHMix.

    摘要: A breathing apparatus has an expiratory flow sensor unit, an expiratory pressure sensor unit, an expiratory pressure regulator, and an expiratory control unit operatively connected to the expiratory pressure sensor unit for a feedback control of an expiratory pressure during an expiratory phase of a breathing cycle. The expiratory control unit is adapted to provide a real time target pressure value during the expiratory phase to the expiratory pressure regulator for adjusting a desired positive end expiratory pressure (PEEP) level (PEEPset) based on an inspiratory tidal volume of an inspiratory phase of the same breathing cycle and a currently accumulated expiratory tidal volume measured by the expiratory flow sensor unit. In this manner advantageous regulation of PEEP with minimized work of breathing is obtained.

    摘要: An acoustic gas monitor has a measurement chamber into which a reference gas of known composition is received and is provided with a wall section for the selective transmission of a gaseous substance to be monitored between the reference gas internal the chamber and a host gas externally of the chamber. An acoustic velocity meter is arranged to supply to an analyzer a signal indicative of an acoustic velocity within the mixture of reference gas and gaseous substance in the chamber. The analyzer being programmed to derive, from the velocity measurement made within the single chamber, information relating to the level of the gaseous substance to be monitored.
