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： An acoustic gas analyzer for gas mixture has an acoustic velocity meter that provides a first output dependent on a detected transmission of acoustic energy through a gas to be analyzed, a temperature probe having a probe time constant that provides a second output indicative of a measured temperature of the gas, and a calculation unit that receives the first and the second outputs and determines compositional information of the gas therefrom. A signal processor is connected between the acoustic velocity meter and the calculation unit and temporally adapts the amplitude of the first output from the meter in a manner dependent on the probe time constant and provides a temporally adapted first output for use as the first output within the calculation unit.

摘要： A mechanical breathing aid has first and second inlets respectively connectable to a source of air and a source of oxygen. A mixing location is in gaseous communication with the first and second inlets, at which controlled amounts of air and oxygen from the respective inlets are mixed. An acoustic analyzer operates during a measurement procedure to access a moisture content value for air from the source of air, to generate acoustic velocity-related information from acoustic energy interaction with the breathing gas, and to determine therefrom an oxygen content. The analyzer operates during a calibration procedure to generate acoustic velocity-related information from acoustic energy interaction with air from the source of air, and to determine therefrom an oxygen content value for the air from which is determined a moisture content value for air.
